This document provides information on abdominal paracentesis including:
1. It defines paracentesis as a procedure where a needle is inserted into the peritoneal cavity to obtain ascitic fluid for diagnostic or therapeutic purposes.
2. The indications for paracentesis include diagnostic testing of new ascites, suspected infections, and therapeutic removal of over 5 liters of fluid for relief of symptoms.
3. Potential complications include failed fluid collection, persistent leaks, infections, hematomas, organ perforation, and hypotension. Proper technique and monitoring can help reduce risks.
Venous thromboembolism (VTE) can be the first sign of an underlying occult or undiagnosed cancer. The risk of occult cancer is higher in patients with unprovoked VTE compared to those with VTE from a provoking factor. Limited screening is recommended for patients over age 40 presenting with unprovoked VTE, including a complete blood count, basic metabolic panel, chest imaging, and consideration of tumor markers based on risk factors. More extensive screening with CT scans is not supported by evidence of improved outcomes and poses risks of unnecessary anticoagulation withdrawal or additional testing. Ongoing surveillance beyond initial screening may be warranted in certain high risk cases such as recurrent unprovoked VTE

This document discusses the prevalence of carotid artery atherosclerosis and stenosis in patients with peripheral arterial disease (PAD). The main points are:
1) Over 85% of patients with PAD also had carotid plaques, indicating a high rate of co-occurrence of carotid and peripheral atherosclerosis.
2) 11.68% of patients with symptomatic PAD had significant carotid stenosis (>50%), compared to 4% of patients without PAD, showing PAD patients have an increased risk of carotid stenosis.
3) Screening for asymptomatic carotid stenosis is important for PAD patients, especially those with an ankle-brachial index <0.7, as the prevalence of asymptomatic carotid stenosis increases with lower ABI values.
1. Pulsatile venous flow in the legs can occur in certain abnormal conditions such as heart disease, severe chronic venous insufficiency, and arteriovenous fistulas.
2. The document describes a case of a 57-year-old man with severe left leg chronic venous insufficiency and refractory leg edema and thrombophlebitis who was found to have a congenital femoral arteriovenous fistula causing high venous pressures.
3. Pulsatile venous flow was detected throughout the deep and superficial venous systems of the left leg in this case and was attributed to the presence of the arteriovenous fistula as the underlying cause of the patient's chronic venous ins
This document discusses methods for evaluating venous reflux disease, including air plethysmography (APG), photo plethysmography (PPG), duplex ultrasound, and their correlations with clinical severity. PPG uses venous refill time (VRT) to identify reflux, with VRT under 10 seconds indicating severe reflux. Duplex ultrasound visually identifies reflux and its pathway. While PPG is cheap and easy, duplex ultrasound provides more detailed anatomy and is needed for more severe disease. Together, PPG and duplex ultrasound provide accurate diagnosis of chronic venous insufficiency prior to potential surgery.
Ultrasonography Doppler is useful in differentiating carotid occlusion from near-occlusion. Near-occlusion is defined as severe stenosis at the bulb followed by collapse of the distal ICA (string sign). Total occlusion is characterized by absence of any flow in the extracranial ICA, while near-occlusion may show variable flow patterns. Doppler criteria for stenosis grading do not apply in near-occlusion/occlusion. CT or MR angiography can help confirm ultrasound findings of total versus near occlusion. Optimizing Doppler parameters is crucial to avoid false positive occlusion diagnoses.
Elastografia is a useful technique for evaluating the age of deep vein thrombosis (DVT) that can complement ultrasound and Doppler examinations. Fresh thrombosis appears green on elastography due to the soft, friable nature of new clots. As clots age and organize, they take on a more blue appearance as fibrosis increases their stiffness. Studies in animals and limited human studies indicate elastography may help distinguish between acute, subacute, and chronic DVT, aiding therapeutic decision making. While more research is still needed, elastography shows potential as a noninvasive method for DVT staging.
The document discusses predictive factors for the development of post-thrombotic syndrome (PTS) following deep vein thrombosis (DVT). Some key points:
- Proximal DVT, ipsilateral DVT recurrence, poor anticoagulation, incomplete DVT resolution, and older age are risk factors for PTS.
- Elevated C-reactive protein levels above 5 mg/L at 12 months post-DVT are strongly associated with PTS development, suggesting persistent inflammation plays an important role.
- Higher D-dimer levels 4 months post-DVT may help predict those at higher risk of PTS who could benefit most from preventive compression stockings.
The document discusses the need for a holistic approach to treating chronic venous disease (CVD). It defines CVD and describes the venous anatomy and physiology. It discusses the pathophysiology of CVD including valve incompetence and reflux. Diagnosis involves physical exam, imaging like duplex ultrasound and treatment options including conservative therapies, interventional procedures like sclerotherapy and ablation, and surgical options like ligation and stripping. The importance of classification systems like CEAP and guidelines in developing a common language for CVD is emphasized.
This document discusses cardiovascular risk and adherence to treatment. It defines key terms like adherence, compliance, persistence, and non-adherence. It notes that poor adherence is a major reason for suboptimal clinical benefits. It also discusses factors that influence adherence like the medication, patient, and healthcare system. Non-adherence can increase risks of stroke, death, hospitalizations and costs. Long-term adherence to medications for conditions like hypertension and statins is often low, around 50%. Improving adherence requires addressing multiple barriers and ensuring patients are involved in treatment decisions.
(1) Inflammation plays a key role in the pathogenesis of acute deep vein thrombosis (DVT). Activation of the endothelium generates signals that recruit leukocytes and induce tissue factor production, initiating the coagulation cascade and thrombus formation.
(2) Chronic inflammatory diseases are associated with an increased risk of DVT due to a proinflammatory and procoagulant state. Patients with inflammatory bowel disease have over a 2-3 times higher risk than the general population.
(3) Inflammation in DVT can be targeted through heparins, statins, sulodexide, and potentially IL-10, which inhibit leukocyte activation and adhesion, reduce cytokine production, and protect the endothe
1. The document discusses reflux in the venous system, including anatomy, physiology, diagnostic methods, and classifications. It notes that reflux can occur in the superficial or deep venous systems or in perforating veins.
2. Duplex ultrasound is a key noninvasive method for evaluating venous reflux, and standardized techniques like patient positioning and provocative maneuvers are important for reliability. Reflux patterns and durations are evaluated.
3. Reflux in the deep venous system and perforating veins is clinically significant as it can contribute to skin changes and ulceration in chronic venous insufficiency. Reflux evaluation over time can identify progression.
1. Continuous peritoneal drainage is an option for refractory ascites in cirrhosis patients. It involves placing a peritoneal drainage catheter to drain 2-4 liters of ascites per day.
2. Complications of drainage include post-paracentesis circulatory dysfunction which can be prevented by administering albumin.
3. Case studies demonstrate effective ascites control with drainage catheters in cirrhosis patients with refractory ascites. Close monitoring is needed to watch for infection risks and electrolyte abnormalities.

MORPHOLOGIC AND FUNCTIONAL MODIFICATIONS OF COMMON CAROTID ARTERIES IN HYPERT...ALEXANDRU ANDRITOIU
This study evaluated morphologic and functional parameters of common carotid arteries in 100 hypertensive patients divided into three age groups. Results showed a significant relationship between age and increases in carotid diameter and wall thickness. Atherosclerosis and plaque formation increased with age, particularly in those over 60. Both aging and hypertension contributed to reduced arterial distensibility and stiffness. In conclusion, aging exacerbates the effects of hypertension on the structure and function of carotid arteries.
