Infective Endocarditis- surgical indication & principle of surgery
this presentation is to give idea about surgical indication for Infective Endocarditis and what are the principle of surgery for infective endocarditis.
complications fess
This document discusses potential complications from functional endoscopic sinus surgery (FESS) and their management. Some common complications include orbital injuries such as damage to the lamina papyracea or periorbita, periorbital emphysema, intraorbital hematoma, damage to nerves or muscles. Risk factors include dehiscence of the lamina papyracea, revision surgery, extensive disease, and distorted anatomy. Management depends on the specific complication but may include observation, antibiotics, steroids, repair, decompression, or intervention from an ophthalmologist. Preventing complications requires careful preoperative planning including CT scans, optimal surgical field preparation, identifying landmarks properly, and being meticulous during surgery
Surgery for atrial fibrillation abhijit presentation
this presentation starts with the description of atrial fibrillation and goes on to describe the basis of it's surgical cure, viz. The Maze procedure. I then describe the technical aspects of Maze 1,2,3,4...
Brachiocephalic fistula
1. The document describes the procedure for creating a brachiocephalic fistula, which involves using the cephalic vein in the arm to access the brachial artery for hemodialysis access.
2. Key steps include identifying a suitable vein and artery via preoperative imaging and dissection, creating a longitudinal arteriotomy in the brachial artery, and performing a running anastomosis between the artery and vein using 6-0 suture.
3. Postoperatively, the fistula is examined for a thrill and hand ischemia before closure of the wound.
"How I Do It" Thoracoabdominal Aneurysm Repair
This document outlines the surgical plan and procedure for replacing the descending thoracic aorta with a graft. Key steps include: preoperative localization of an important artery; preparing the patient with blood products, lines, and antibiotics; making an incision and removing a rib for exposure; dividing surrounding tissues to access the aorta; clamping and replacing the aorta with a graft from the subclavian artery down; reattaching arteries along the new graft; and closing the chest and monitoring the patient in recovery.
A v fistula in heamodialysis
The document summarizes techniques and complications of arteriovenous (A-V) fistulas used for hemodialysis. It discusses types of fistulas including autogenous and graft fistulas. It describes surgical techniques for creating different types of fistulas such as side-to-side, end-to-side, and end-to-end anastomoses. Common complications include early failure from thrombosis, aneurysm formation, infection, ischemic changes causing steal syndrome, and venous hypertension. Care of the fistula involves exercises and avoiding blood pressure checks or intravenous lines in the fistula arm.
Fistula (Arteriovenous fistula -AVF)
An arteriovenous fistula (AVF) is created by surgically connecting an artery directly to a vein, allowing blood to flow from the artery to the vein. This creates a continuous circuit from the heart. The most common sites for AVFs are the wrist, elbow, and upper arm.
Cannulation of the AVF is important to maintain patency and prevent complications. It can be done using either a rope ladder technique, which rotates sites, or a buttonhole technique, which uses the same site. Proper needle size, angle, and hemostasis are important to prevent issues like infiltration or bleeding.
Frontal venography
Frontal venography is a technique where contrast dye is injected into the frontal vein or its tributaries to visualize the orbital veins. Radiographs are then taken to determine if there is an orbital space-occupying lesion in patients with unilateral exophthalmos. It can help diagnose the nature, site and size of orbital lesions when other imaging fails. The technique involves injecting contrast into the frontal vein to outline the venous drainage from the superior ophthalmic vein to the internal jugular vein. Proper positioning and subtraction techniques are important to clearly visualize the cavernous sinuses.

AV FISTULA A PROCEDURE FOR HAEMODIALYSIS HAS MANY COMPLICATIONS AND LEADS TO FAILURE OF FISTULA AND NEED FOR NEW SITE
Aortic repair ppt
This document describes procedures for aortic valve replacement and repair. It discusses excising the native aortic valve and implanting a prosthetic valve using sutures placed around the annulus. For small annuli, the aortic root can be enlarged using techniques like the Nicks-Nunez or Konno-Rastan methods which involve patching the aortic wall. The document also outlines techniques for reconstructing valves, including patching leaflet perforations or tears.
REBOA
This document discusses resuscitative endovascular balloon occlusion of the aorta (REBOA), which involves placing a balloon catheter in the aorta to control hemorrhage and increase blood pressure in cases of traumatic cardiac arrest or hemorrhagic shock. REBOA can occlude the aorta at different levels depending on the clinical need and is used as a bridging technique to allow time for definitive repair, not as a definitive solution. The document outlines the anatomy, indications, contraindications and steps for performing REBOA, including arterial access, balloon selection and positioning, inflation, deflation, and removal. It emphasizes that REBOA requires maintenance and is not a definitive solution, advising to think carefully
Av fistula examination - dr. tarek fayez
Physical examination is an important tool for evaluating arteriovenous fistulas (AVFs) used for hemodialysis access. The summary examines key aspects of physically examining an AVF:
1) Inspection of the AVF and arm includes examining the skin, cannulation sites, and checking for aneurysms. The size, length, and branches are also evaluated.
2) Techniques like arm elevation, pulse examination, thrill assessment, and pulse augmentation help detect stenosis or other problems like vascular steal syndrome.
3) Accessory veins can be identified by looking for multiple veins or palpating branches, and evaluating flow changes when compressing sections of the access.
Conduits used in CABG.
The document discusses conduits used in coronary artery bypass grafting (CABG). It describes the history of CABG, beginning with Alexis Carrel's description in the early 1900s. It outlines the three eras of CABG and discusses key pioneers like Michael DeBakey and Rene Favaloro. The document then describes the different types of arterial and venous conduits used in CABG, focusing on the internal thoracic artery and radial artery. It discusses the anatomy, histology, harvesting techniques, and patency rates of different conduits.
Shunt Surgery
Dr. Yashveer Singh discusses the history and techniques of shunt surgery. Key points include:
- Shunt surgery diverts cerebrospinal fluid (CSF) from the brain ventricles to another site to treat hydrocephalus. It has evolved from early 20th century drainage techniques to modern shunt systems using silicone catheters and programmable valves.
- Careful planning is required to determine the optimal insertion sites for ventricular and distal catheters based on patient history and anatomy. Meticulous surgical technique and attention to details can reduce complications like infection and blockage.
- The goals of shunt surgery are to achieve normal intracranial pressure and neurological function while
Vascular access in pediatrics
Central venous catheters can be inserted via the internal or external jugular veins using the Seldinger or cutdown techniques. The Seldinger technique involves inserting a needle and guidewire, then dilating and inserting the catheter under fluoroscopy guidance. The cutdown technique requires making an incision to directly access and puncture the vein. Port catheters involve inserting a catheter and subcutaneous reservoir, while Broviac/Hickman catheters have a Dacron cuff. Complications can include pneumothorax, hemothorax, malposition, or arterial puncture.
Vascular access in neonates small children dr. rasha helmy
This document discusses vascular access options for hemodialysis in neonates and small children. Peritoneal dialysis is generally preferred but is not always feasible or effective. Central venous catheters provide adequate flow for dialysis but have high failure and complication rates. Arteriovenous fistulas, the preferred access for adults, are not usually possible in small children. Alternative options discussed include peripherally inserted central catheters and umbilical venous catheters. The risks and benefits of different vascular access sites like internal jugular, subclavian and femoral veins are also reviewed.
Angiography and Angioplasty
This document discusses angiography and angioplasty procedures. It explains that angiography uses imaging techniques to visualize blood vessels, while angioplasty widens narrowed vessels. The document outlines different types of each procedure and describes how they are performed. It also discusses stents, which are used to prop open vessels after angioplasty and discusses advantages and disadvantages of various stent materials.
Mitral valve repair
This document provides information on surgical repair of the mitral valve for acquired mitral valve disease. It discusses that mitral valve repair is preferred over replacement when possible as it has lower risks and better preserves heart function. Techniques for repair include annuloplasty to reshape the valve ring, leaflet resection or suturing to address prolapse, and creation of artificial chordae to improve leaflet coaptation. The quality of repairs must be assessed using techniques like saline testing to ensure adequate valve function is restored.
Internal iliac ligation
Internal iliac artery ligation (IIAL) is a technique to control pelvic hemorrhage by ligating the internal iliac arteries. It preserves fertility and can be life-saving when other options risk compromising the patient. IIAL works by reducing blood flow and pressure in the pelvis, allowing clots to form and stop bleeding. The pelvis has extensive collateral circulation, so ligation does not cause ischemia. IIAL is effective for prophylactic or therapeutic control of hemorrhage from the uterus, cervix, or broad ligament. It carries risks if not performed carefully to avoid injuring nearby structures like veins and ureters.
Seminar valve reconstruction and replacement
Valve reconstruction is a surgical technique used to repair defects in heart valves. It provides an alternative to valve replacement. In the US, about 99,000 heart valve operations are performed each year, most commonly to repair or replace the mitral or aortic valves which are on the left side of the heart. Valve repair techniques include commissurotomy to open narrowed valves, annuloplasty to provide support with a ring, and reshaping, patching or shortening valve leaflets. Conditions requiring surgery include severe valve damage or complications from issues like infection.
Angioplasty & Stents
This document discusses angioplasty, which is a minimally invasive procedure to mechanically widen blocked or narrowed blood vessels caused by conditions like atherosclerosis and hypertension. It describes different types of angioplasty used to treat blockages in coronary arteries, peripheral arteries, carotid arteries, and renal arteries. The procedure involves passing a balloon catheter into the blocked vessel, inflating the balloon to crush blockages, and sometimes implanting a stent to keep the vessel open. Risks include reaction to contrast dye, bleeding, heart attack, and infection. Most patients are monitored after angioplasty and prescribed anti-clotting drugs during recovery.
Av fistula 3 al mansoura aldawly - nephrolody day dr aboelfotoh
This document provides guidance on using color Doppler ultrasound to assess arteriovenous (AV) fistulas in hemodialysis patients. It outlines the objectives of teamwork, patient respect, and basic clinical knowledge. It describes the strategy for color Doppler exams in three stages: preoperative mapping, postoperative assessment of maturity and function, and assessment of complications. The basics of Doppler are reviewed, and the normal and abnormal ultrasound findings for each stage are presented, including criteria for fistula maturity. Complications such as stenosis, thrombosis, aneurysm, steal syndrome, and high output cardiac failure are described. The importance of clinical findings and interdisciplinary teamwork to prevent, predict, and early manage fistula complications is emphasized.
Acs0612 Aortoiliac Reconstruction
1) Aortoiliac occlusive disease is caused by atherosclerosis and impairs blood flow to the lower body, causing symptoms ranging from claudication to gangrene.
2) Surgical options for revascularization include aortoiliac endarterectomy, iliofemoral bypass, and aortofemoral bypass.
3) Aortoiliac endarterectomy involves exposing the aorta and iliac arteries through a transperitoneal incision, performing a longitudinal arteriotomy, and removing the atherosclerotic plaque. Short graft interposition may be needed if the vessel wall is too thin.
Principles of vascular anastomosis
The principles of vascular repair with sutures were established in the first decade of the 20th century by Alexis Carrel, who in 1912 was awarded the Nobel Prize for medicine for his work .Since then, technical refinements of suture materials have made possible surgical reconstruction of most arteries from the root of the aorta to microvascular anastomosis or repair of the smallest vessels, e.g., digital arteries or those on the surface of the brain.
Cerebral angiography technique
Digital subtraction angiography (DSA) is the gold standard for evaluating the cerebral vasculature. It involves injecting iodinated contrast material into arteries and using subtraction techniques to visualize vessels. The normal anatomy includes the circle of Willis and branches of major arteries. Variants are common. DSA is used to diagnose conditions like aneurysms and arteriovenous malformations. Newer digital systems provide 3D reconstruction and less radiation exposure compared to older techniques. DSA remains an important tool for interventional procedures and treatment planning of complex vascular lesions of the brain.
Aortoiliac occlusion rx
A 79-year-old woman presented with severe leg pain and acute renal failure. Examination showed absent leg pulses. Imaging showed aortoiliac occlusions. The next step was a CT angiogram, which confirmed aortoiliac occlusions. Percutaneous revascularization was then performed by obtaining femoral access and crossing the occlusion with guidewires. Angioplasty and stenting of the aortoiliac bifurcation and infrarenal aorta were performed, resulting in excellent blood flow.
Radial artery pseudoaneurysm
1) A 74-year-old male developed a large radial artery pseudoaneurysm following transradial coronary angiography. Ultrasound-guided compression was unsuccessful in treating the pseudoaneurysm.
2) Due to the large size of the pseudoaneurysm and failure of conservative treatment, the patient underwent surgical repair.
3) At one month follow up after surgical repair, the radial artery patency was restored with complete healing of the access site and no recurrence of the pseudoaneurysm.

Vertebral artery pseudo-aneurysms and dissections are known to occur as a result of mechanical
manipulations of the cervical region, traumatic injury, spontaneously and iatrogenic injury because of central
venous catheterization. Central venous lines have become an integral part of patient care, but they are
not without complications. Vertebral artery injury (leading to pseudo-aneurysm and dissection) is one of
the rarer complications of central venous catheter placement. We report a case of inadvertent vertebral
artery catheterization during a dialysis catheter placement which subsequently demonstrated arterial
blood. Duplex ultrasound and computed tomographic (CT) scan confirmed vertebral artery catheterization.
It was successfully treated with open surgical technique by the vascular surgeon because of the size of
catheter and subsequent requirement of artery repair. There were no neurological sequelae. Open surgical
repair remains the gold standard of treatment. Endovascular repair of vertebral artery pseudo-aneurysms
has been described with promising outcomes, but long-term results are lacking. This case report describes
the rare iatrogenic event of vertebral artery injury and reviews its etiology, diagnosis, complications, and management.

EXTREMITY_VASCULAR_TRAUMA.pptx
Professor Abdulsalam Y Taha presents several cases of extremity vascular injuries managed at his medical unit to emphasize principles for proper care of such patients. Limb salvage rates of 70-95% are reported in major centers for patients with limb arterial trauma when prompt diagnosis, resuscitation, hemorrhage control, and revascularization are achieved. However, primary amputation may be necessary for limbs that are too severely damaged or when prolonged ischemia time makes salvage unlikely to succeed. The goal of vascular trauma management is to save both the patient's life and limb through early recognition, exploration, and appropriate repair or reconstruction of injured blood vessels.
Aortic Valve Sparring Root Replacement David vs yacoub
The document discusses different techniques for aortic valve-sparing operations, including the remodeling technique developed by Yacoub and the reimplantation technique developed by David. It describes the technical steps for each procedure and compares their early mortality rates and long-term outcomes. While both techniques can successfully preserve native valve function, the reimplantation technique may be preferable to remodeling for certain patient anatomies or pathologies like bicuspid valves, Marfan syndrome, or acute aortic dissection. Intraoperative imaging is important for assessing valve competence after repair.
David vs yacoubf
The document discusses different techniques for aortic valve-sparing operations, including the remodeling technique and the reimplantation technique. It provides details on how each technique is performed surgically and discusses findings from studies comparing the techniques. The main points are:
1) The remodeling technique preserves some aortic root distensibility but the reimplantation technique causes higher pressure gradients due to a more rigid fixation of the valve.
2) Bending deformation of the valve leaflets is higher for both techniques compared to native aortic roots, due to the use of synthetic graft material.
3) Aortic root distensibility decreases for both techniques compared to native roots, with less distensibility observed with
Spectrum Of Ct Findings In Rupture And Impendinging Rupture Of AAA
This document discusses CT imaging findings of ruptured and impending rupture of abdominal aortic aneurysms. CT is the preferred imaging method for evaluating acute aortic syndrome due to its speed and availability. Findings indicative of rupture include retroperitoneal hematoma adjacent to the AAA and active extravasation of contrast. Findings predictive of impending rupture are large aneurysm size, lack of circumferential thrombus, discontinuity of wall calcifications, and the hyperattenuating crescent sign. Infected, inflammatory, and fistula-related aneurysms are also described.
Posterior approach aortic root enlargement in redo aortic
This document discusses aortic root enlargement using a posterior approach for redo aortic valve replacement. It provides details on the surgical technique used, which involves extending the aortotomy incision along the commissure between the left coronary and noncoronary sinuses across the anterior mitral leaflet and using a Dacron patch to enlarge the annulus. Results from a study of 25 patients found a hospital mortality rate of 8% due to low cardiac output, with 3 patients requiring reexploration for bleeding. The conclusion is that aortic root enlargement using this posterior approach can be done safely and does not increase surgical risk. However, the main limitation is the small number of patients and lack of long-term follow-
Aortic Valve Sparring Root Replacement
Both the remodeling and reimplantation techniques aim to preserve the native aortic valve in patients with aortic root aneurysms. The remodeling technique involves excising the diseased sinuses and reattaching the valve within a graft, reconstructing the sinuses. The reimplantation technique reimplants the valve within a graft anchored at the aortoventricular junction. Studies have found slightly better long-term outcomes with reimplantation, especially in conditions like Marfan syndrome or dissection, though both techniques have good results. Neither technique fully restores the normal biomechanics and stress patterns of the native aortic root.
Resection of a large carotid
This case report describes the resection of a large carotid artery aneurysm under cervical epidural anesthesia in a 22-year-old woman. Cervical blockade was not possible due to the location and size of the aneurysm. The patient underwent cervical epidural anesthesia, which allowed for continuous neurological monitoring during the surgery and early detection of any brain ischemia when the carotid artery was clamped. The large aneurysm was successfully resected over the course of a two hour surgery. The patient recovered well with no neurological defects. The report concludes that cervical epidural anesthesia performed by an experienced anesthetist provides safe neurological monitoring and is an acceptable approach for resecting carotid artery aneurysms when other methods are not possible.

This document discusses vascular anomalies, which are soft tissue lesions caused by aberrant blood vessel growth. It focuses on arteriovenous malformations (AVMs), which are high-flow vascular malformations. The case report describes a 30-year old female patient with a maxillary AVM that caused swelling. Diagnostic angiography revealed the AVM was supplied by the internal maxillary artery. To treat the AVM, interventional radiography was performed using selective transarterial embolization of the maxillary artery with polyvinyl alcohol particles. This successfully occluded the vessels feeding the AVM with no complications for the patient.
Anevrisme suprarenale
This document describes the surgical technique for repairing type IV thoracoabdominal aortic aneurysms and suprarenal abdominal aortic aneurysms. The technique involves a retroperitoneal approach with suprarenal or supravisceral aortic clamping. Renal and intestinal arteries are continuously perfused using a passive shunt from the right axillary artery to protect these organs from ischemia during the procedure. The proximal anastomosis is beveled with the tip at the level of the celiac trunk. Patch insertion of visceral artery origins allows implantation into the graft. Renal protection techniques aim to limit ischemia time to less than 45-50 minutes to prevent renal failure, and may include cold perfusion, prostagland
Endovascular repair of thoracic and abdominal aortic aneurysms
Endovascular repair of thoracic and abdominal aortic aneurysms has significantly reduced mortality and morbidity compared to open surgery. It involves placing stent grafts using catheters to exclude aneurysms from blood flow. Proper patient selection based on aneurysm anatomy and vessel access is important for success. Follow up imaging is needed to monitor for complications like endoleaks. Mid-term results show endovascular repair provides good outcomes with 85% survival at 18-24 months for thoracic aneurysms. It has emerged as an alternative to open surgical repair for properly selected abdominal aortic aneurysm cases.

Caseof wide QRS tachycarfdia ablation
A 17-year-old male presented with recurrent episodes of rapid heart palpitations. During an episode, electrocardiography (ECG) showed a wide complex tachycardia. An electrophysiology study was performed, which induced the clinical tachycardia and identified it as an atrial flutter conducting with 2:1 block to the ventricles. Linear radiofrequency ablation of the cavo-tricuspid isthmus was performed to cut the reentry circuit, requiring 8 applications to achieve bidirectional block and render the tachycardia non-inducible.

Coronary artery dilatation is an uncommon finding and is incidentally found during diagnostic coronary angiography or at necropsy.
The pathogenesis of dilatation of coronary arteries is still not very
well understood and therapeutic strategies are not clear. It is useful to know the difference between aneurysm and ectasia. In this
report we demonstrate the diagnostic workup of an asymptomatic
patient with a remarkable snakelike dilatation of the right coronary
artery with unique convolute. For the first time we used intracoronary injection and simultaneous echocardiographic visualization
of contrast agent (Sonovue) to proof a fistula to the coronary sinus.
Like our patient, most of the patients are asymptomatic in absence
of coronary artery disease and we decided on a conservative approach because of his very complex anatomy

This document describes a rare case of a patient with both total anomalous pulmonary venous connection (TAPVC) and cor triatriatum. A pre-operative cineangiocardiogram ruptured the membrane dividing the left atrium in cor triatriatum, improving hemodynamics. Successful corrective surgery was then performed, involving resection of the cor triatriatum membrane and anastomosis of the left atrium to the pulmonary veins. At a six month follow up, the patient was doing well with mild residual effects.
Case report iliac aneurysm
This case report describes a 69-year-old male patient who presented with an isolated right common iliac artery aneurysm measuring 8 cm in diameter. During pre-operative workup for planned open surgical repair, the patient's condition deteriorated and imaging showed rupture of the aneurysm. The patient underwent an emergency retroperitoneal surgical procedure to ligate the right iliac artery, perform an extra-anatomic femorofemoral bypass, and repair the ruptured aneurysm. Post-operatively, the patient recovered well with all pulses intact. Isolated iliac artery aneurysms are rare but can rupture with high mortality if not repaired. Both open surgical and endovascular techniques are used for treatment.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

- 5. Methods 33 years old gentleman came to our hospital with ruptured non-coronary sinus of valsalva into right atrium. Operation was done on 15.11.12. Non coronary sinus was hugely dilated with a perforation at apex . Double ended pledgeted horizontal mattress suture was applied to aneurismal area around the perforation in normal healthy tissue. Right atrium was opened , about 4cm long vegetation was found, it was excised .Double ended pledgeted horizontal mattress suture was applied around the perforation site in Right atrium. PTFE patch closure of aneurismal part of Non coronary sinus of aorta was done,sutures were passed through normal healthy sinus tissue. Now aortic cusp coaptation was checked by saline test –found good coaptation. Cross clamp was removed .Weaning from CPB was done uneventfully .TEE was done after weaning from CPB—no leakage was found through the patch are and no aortic regurgitation was present.
