This document discusses various pathologies of intracranial vascular disease including aneurysms, arteriovenous malformations (AVMs), cavernomas, and venous anomalies. It provides details on the presentation, diagnosis, and treatment of each condition. Key points include that aneurysms can cause subarachnoid hemorrhage and have risks of rupture related to size, location, and other factors. AVMs are abnormal connections between arteries and veins without an intervening capillary bed that can cause hemorrhage. Cavernomas are venous malformations that can cause seizures or hemorrhage. Venous anomalies are the most common type and appear as thickened veins on imaging.

“Vein of galen Malformation” ppt
This document discusses a case of an 8-hour-old male infant presenting with breathlessness, abdominal distension, and swelling in the lower limbs and sacral area, who was diagnosed with a vein of Galen malformation. Vein of Galen malformations are congenital abnormalities that develop during weeks 6-11 of fetal development. They can cause congestive heart failure, hydrocephalus, and developmental delays. Investigation with cranial ultrasound, MRI/CT, and angiography are used for diagnosis. Treatment involves a multidisciplinary team and endovascular embolization of the abnormal vessels, though care must be taken with neonates. Prognosis has improved with advances in minimally invasive treatments.
Paediatric Neurovascular Malformations
This document discusses differences in pediatric vascular malformations compared to adults. Key differences include more difficult cerebral eloquence assessment, multifocality, involvement of the entire venous system, and different anatomical and physiological characteristics in children. It covers various types of pediatric vascular malformations like pial AVMs, vein of Galen malformations, pial arteriovenous fistulas, dural arteriovenous shunts, proliferative angiopathy, cavernous malformations, developmental venous anomalies, sinus pericranii, and capillary telangiectasia. For each type, it discusses presentation, imaging findings, classification, treatment options and considerations for pediatric patients. Endovascular embolization is a mainstay treatment, but

The most common cerebral vascular malformations are venous angiomas, which are usually asymptomatic. Arteriovenous malformations (AVMs) are the most common symptomatic cerebral vascular malformations, presenting most often with hemorrhage or seizures in individuals between 20-40 years of age. A vein of Galen malformation is a rare type seen in neonates presenting with high-output heart failure or older individuals with subarachnoid hemorrhage.
Dural arteriovenous fistula & AVM
This document discusses various types of vascular malformations of the brain. It describes arteriovenous malformations (AVMs), dural arteriovenous fistulas (DAVFs), developmental venous anomalies (DVAs), cavernous malformations, and capillary telangiectasias. It provides details on imaging with angiography, CT, and MRI to identify these conditions. It also discusses treatments and classifications like the Borden system for DAVFs. Common locations are the transverse/sigmoid sinus for DAVFs and presentation can include pulsatile tinnitus, cranial nerve palsies, and hemorrhage.
Vein of Galen Malformation
Vein of Galen malformations are rare congenital vascular anomalies that develop between weeks 6-11 of fetal development. They present as an aneurysmally dilated midline deep venous structure fed by abnormal arteriovenous communications. In neonates, they can cause high-output cardiac failure. Older children and adults may present with hydrocephalus, neurological deficits, or seizures. Diagnosis is made through imaging like CT, MRI, and angiography. Treatment involves endovascular embolization of the arteriovenous shunts to reduce cardiac overload and improve neurological outcomes. With advances in interventional neuroradiology, vein of Galen malformations can now be successfully treated with low complication rates.
Cerebral AVM
- Cerebral arteriovenous malformations (AVMs) are vascular abnormalities consisting of a tangled web of arteries and veins with an intervening abnormal capillary bed (nidus).
- They most commonly present in young adults between 30-40 years of age through hemorrhage, seizures, or headaches. The annual risk of hemorrhage is around 2-4% and declines over 5 years for those who have already hemorrhaged.
- Diagnosis involves CT, MRI, and cerebral angiography. Angiography provides the most detailed information about the arterial feeders, nidus, draining veins, and flow dynamics needed for treatment planning. The Spetzler-Martin grading system is commonly used
Avm.23.11
This document describes a case of a 9-year-old female patient diagnosed with seizures who was found to have an arteriovenous malformation (AVM). Imaging including CT, MRI, and DSA confirmed the presence of an AVM. The patient underwent embolization to treat the AVM. AVMs are abnormal tangled collections of blood vessels consisting of arteries and veins without a capillary bed. They can cause seizures, hemorrhage, and neurological deficits. Treatment options include observation, surgery, embolization, radiosurgery, or a combination depending on the size, location, and severity of the AVM.

Cerebral/Pial Arteriovenous Malformation (AVM)
This document discusses cerebrovascular malformations (CVMs) of the brain. It describes that CVMs are disorders representing morphogenetic errors affecting brain arteries, capillaries or veins. It classifies CVMs into two main groups - vascular malformations and hemangiomas. Pial arteriovenous malformations (AVMs) are specifically discussed. Pial AVMs have direct connections between arteries and veins without an intervening capillary bed. They contain enlarged feeding arteries, a nidus of tangled vascular channels, and dilated draining veins. Imaging findings on CT, MRI and cerebral angiography are provided to identify the key components of pial AVMs. Differential diagnoses and clinical management are also reviewed.
Arteriovenous Malformation (AVM) of Brain
Arteriovenous malformations (AVMs) of the brain are abnormal connections between arteries and veins in the brain that bypass the normal circulation. The cause of AVMs is unknown, though they are usually congenital. Symptoms vary depending on the location of the AVM and include brain hemorrhage in over 50% of cases, seizures in 20-25% of cases, and other neurological issues. Diagnosis involves CT, MRI, and cerebral angiogram imaging. Treatment options include surgery for accessible and smaller AVMs, stereotactic radiosurgery for smaller inaccessible ones, and endovascular procedures like using coils for parts of larger AVMs. Outcomes depend on the treatment, with surgery offering up to
Cerebral avm-treatment-modalities.dr tomasz skaba
1. Arteriovenous malformations (AVMs) are congenital abnormalities of blood vessels that create direct connections between arteries and veins in the brain.
2. They most commonly occur in the cerebral hemispheres, particularly in the territory of the middle cerebral artery.
3. Treatment options include surgery, which eliminates the risk of bleeding but carries surgical risks, stereotactic radiosurgery which is non-invasive but takes 1-2 years to work, and embolization which facilitates other treatments but is generally not effective alone. Treatment is tailored based on the size, location, and grade of the AVM.
Brain avm
Brain arteriovenous malformations (AVMs) are abnormal clusters of blood vessels in the brain. They can cause bleeding in the brain or seizures. AVMs are typically treated through surgery to remove the abnormal vessels, procedures to block the blood vessels using embolization, or radiation therapy to damage the vessels. Each treatment has risks of complications like bleeding in the brain, infections, or neurological deficits. The best treatment depends on the size and location of the AVM. Conservative management without intervention may be appropriate for some patients as well.
Vascular malformations
This document discusses various types of vascular malformations. It begins by describing malformations with arteriovenous shunts, including arteriovenous malformations (AVMs), dural arteriovenous fistulas (DAVF), and pial arteriovenous fistulas. It then discusses malformations without shunts such as cavernous malformations, venous malformations, capillary telangiectasia, and Moyamoya disease. The document provides details on the characteristics, presentation, evaluation and treatment of different types of vascular malformations.
Cavernous malformations
Cavernous malformations are vascular lesions composed of thin-walled, blood-filled sinusoids known as caverns. They are angiographically occult and low-pressure. These lesions are caused by mutations in CCM genes that result in abnormal angiogenesis and vascular integrity. This leads to immature and fragile vasculature that is prone to hemorrhage, further activating lesion growth. Histologically, they appear as lobulated reddish lesions containing blood-filled caverns surrounded by hemosiderin staining from previous hemorrhages.
Vascular brain lesions for radiology by Dr Soumitra Halder
- The document discusses various brain vascular lesions including aneurysms, vascular malformations, dural arteriovenous fistulas, and more.
- Aneurysms are abnormal bulges in arterial walls that can rupture and cause subarachnoid hemorrhage. Imaging like CTA can detect aneurysms with over 90% sensitivity. Treatment options include observation, surgical clipping, or endovascular coiling.
- Arteriovenous malformations are tangled masses of abnormal vessels that shunt blood from arteries to veins without an intervening capillary bed. They can cause headaches or neurological deficits. Treatment involves surgical excision, stereotactic radiosurgery, or endovascular embolization.

Cerebral venous thrombosis
This document discusses cerebral venous thrombosis (CVT), including its history, major venous drainage pathways of the cranium, aetiology, neurological features, frequency of sinus involvement, and investigations. It provides details on the dural sinuses, superficial and deep cerebral veins, dural veins, scalp veins, and cervical veins that drain the brain. Common causes of CVT include oral contraceptives, pregnancy, hematological/immunological abnormalities, infections, and malignancy. Headache and focal neurological deficits are frequent symptoms, while impaired consciousness and seizures also occur. Imaging studies like CT, MRI, and angiography along with lumbar puncture are used to diagnose CVT.
Imaging: AV Malformation
1. A 41-year-old man presented with vomiting, altered mental status, and difficulty walking. On examination, he showed signs of brainstem involvement including nystagmus and facial weakness.
2. Imaging and lab tests did not reveal any coagulation abnormalities or structural causes like tumors. A slight elevation in homocysteine levels was found.
3. Cerebral angiography confirmed an arteriovenous malformation (AVM), which are congenital lesions caused by a failure of the embryonic vasculature to fully develop. The Spetzler-Martin grading system was then used to assess the AVM based on its size, location, and venous drainage patterns.
Brain aneurysm
The document discusses brain aneurysms, which are bulging, weak areas in arteries supplying blood to the brain. A brain aneurysm can rupture, causing bleeding in the skull and potentially brain damage or death. While they affect about 1% of the population overall, brain aneurysms are more common in women than men. The most common location for brain aneurysms is at the base of the brain. Risk factors include family history, previous aneurysms, gender, race, high blood pressure, and smoking. Potential symptoms include sudden, severe headaches and neck pain. Diagnosis involves CT, CTA, MRA, or cerebral angiogram scans. Treatment options are surgical clipping or endovascular coiling to prevent blood flow into the aneurys
BRAIN ARTERIOVENOUS MALFORMATION
Brain arteriovenous malformations (bAVM) are abnormal connections of arteries and veins in the brain, forming a tangled web of vessels instead of a normal capillary network treated with multimodalities including, SRS, embolisation and Microneurosurgery.
This slides updates the management of AVM highlighting the importance of SM grading, Pollock radiation grading etc.
Cerebral venous thrombosis
Cerebral venous sinus thrombosis involves blood clots forming in the dural venous sinuses, which drain blood from the brain. It most often affects younger adults and is more common in women. Common risk factors include genetic or acquired prothrombotic conditions, oral contraceptive use, pregnancy, infections, and cancers. Symptoms vary depending on the involved sinus but often include headaches, focal neurological deficits, seizures, and altered mental status. MRI and CT imaging can detect clots and brain abnormalities, while treatment focuses on underlying causes, seizure control, reducing intracranial pressure, and anticoagulation therapy.
CEREBRAL ARTERIO VENOUS MALFORMATIONS
This document provides an overview of cerebral arteriovenous malformations (AVMs). It defines a cerebral AVM as a vascular malformation with direct connections between arteries and veins, without an intervening capillary bed. The key characteristics of AVMs are described, including their demographics, clinical presentations such as hemorrhage and seizures, evaluation with imaging and angiography, grading systems like the Spetzler-Martin scale, and treatment options including surgery, embolization, and radiosurgery. Guidelines for treatment are outlined based on the grade of the AVM, with lower grade AVMs more amenable to aggressive treatment aiming for cure.
Thyroid ppt
This document provides information about arteriovenous malformations (AVMs). It defines AVMs as tangles of abnormal blood vessels that can form wherever arteries and veins exist in the brain or spinal cord. The causes are unknown. Risk factors include family history and history of bleeding. Symptoms vary depending on the location of the AVM and can include seizures, headaches, weakness, and sensory or cognitive changes. Diagnosis involves angiography, CT scans, MRI, or MRA. Treatment options include microsurgery, radiosurgery, and embolization to destroy the AVM.
Cvt
Cerebral venous thrombosis is an underdiagnosed cause of neurological deterioration where imaging plays a key role. It involves clot formation in the dural sinuses or cerebral veins. On CT, a direct visualization of clot appears as a "dense clot sign" seen in one third of cases. MRI is now often used and can show thrombus as absent flow voids on spin echo sequences or hyperintense on T1-weighted imaging in later stages. CT or MR venography can clearly depict thrombosed vessels but artifacts must be considered. Angiography remains the reference standard for severe cases where intervention is planned.

It provides details on the prevalence, types, clinical presentation, imaging findings, and treatment of different conditions. In particular, it notes that brain aneurysms are abnormal bulges in brain arteries that can rupture and cause life-threatening bleeding. Imaging tools like CT, MRI, and DSA are used to detect aneurysms and other vascular abnormalities. Moyamoya disease involves progressive stenosis of carotid arteries and formation of collateral vessels visible on angiography.
357 Cerebral venous and sinus thrombosis
This document summarizes cerebral venous and sinus thrombosis. It discusses the pathogenesis, which can involve thrombosis in cerebral veins leading to venous hypertension and hypoxia. Risk factors include trauma, hypercoagulable states, infections, oral contraceptive use, and idiopathic causes. Clinical findings often include headache, seizures, neurological deficits, and features depending on the site of thrombosis. Diagnosis involves CT, MRI, MRA and MRV to detect thrombus. Treatment involves anticoagulants like heparin and warfarin, thrombolytics through interventional radiology, and occasionally surgery for complications. Outcomes depend on factors like coma, site of thrombosis, and degree of intracranial pressure.

Ventricular septal defects (VSDs) are one of the most common types of congenital heart defects. They occur when there is an abnormal opening in the dividing wall between the lower chambers of the heart (the ventricular septum). VSDs can vary in size and location. Small, restrictive VSDs may close on their own, while larger defects can cause increased blood flow to the lungs which can lead to pulmonary hypertension if left untreated. VSDs are typically diagnosed and monitored using echocardiography. Treatment options range from observation for small defects to surgical closure for larger VSDs.

Complete Information on Cerebral Aneurysm or Brain Aneurysm
A cerebral aneurysm is a bulging, weak spot on a blood vessel in the brain that can fill with blood and put pressure on surrounding tissues. It may also leak or rupture, spilling blood into the brain. Cerebral aneurysms most often occur along arteries at the base of the skull. They can be present from birth or develop later due to injury. Symptoms may include headaches, double vision, or eye pain if the aneurysm pushes on brain structures. Tests like CT scans, MRIs, eye exams, and angiograms can diagnose cerebral aneurysms and detect any bleeding in the brain.

Classic sign crbral aneurysm pbl
This document classifies cerebral aneurysms into three cases: ruptured, leaking, and unruptured. [1] A ruptured aneurysm causes a sudden, extremely severe headache described as the "worst headache ever" along with nausea, vomiting, neck stiffness, vision changes, sensitivity to light, seizures, drooping eyelid, loss of consciousness, or confusion. [2] A leaking aneurysm may cause a mild headache and will likely rupture fully. [3] An unruptured aneurysm may be asymptomatic, but a large one could press on brain tissue and cause eye or facial pain, vision changes, numbness, or weakness. The defining symptom of an aneurysm is the extreme rapid onset of

Finally, it notes some potential etiologies of intracranial aneurysms such as being idiopathic, traumatic, infectious, or radiation-induced.
Presentation1.pptx, radiological imaging of brain av malformation.
This document discusses arteriovenous malformations (AVMs) of the brain. It begins by defining AVMs and describing their three types. It then discusses the epidemiology of AVMs, noting they are usually congenital but develop over time, and are typically diagnosed around age 31. Clinical presentations of AVMs include being asymptomatic, seizures, headaches, ischemic events, and hemorrhaging. The pathology section describes the components of an AVM including feeding arteries, nidus, draining veins. Location is typically supratentorial. Radiographic features on CT, MRI, MRA, and DSA are discussed. In summary, this document provides an overview of brain AVMs, including their definition, epidemiology, clinical
Cerebral Hemorrhage By Arlyn M. Valencia, M.D. Associate Professor, Universit...
The document discusses different types of hemorrhagic stroke including primary intracerebral hemorrhage, subarachnoid hemorrhage, and hemorrhage from cerebral amyloid angiopathy. Risk factors for hemorrhagic stroke include hypertension, aging, cigarette smoking, and alcoholism. Management of hemorrhagic stroke focuses on controlling bleeding, removing blood from the brain, managing increased intracranial pressure, and treating any underlying correctable causes.
brain AVMs
Microsurgery, embolization, and radiosurgery are the main treatment options for cerebral arteriovenous malformations (AVMs). Microsurgery allows for immediate treatment but risks are higher for deep or complex AVMs. Embolization has delayed effects and risks bleeding during the latency period. Radiosurgery requires 2 years for effects but has risks of radiation side effects. For low grade AVMs, microsurgery provides nearly 100% obliteration rates and best seizure and rebleeding outcomes, though risks are higher for complex cases. Unruptured AVMs may be initially managed medically but ruptured AVMs generally warrant treatment due to increasing rebleeding risks. A multidisciplinary approach is typically

vascular anomalies.pptx
Virchow and Wegener were the first to classify vascular anomalies in 1880, dividing them into angiomas and lymphangiomas. Mulliken and Glowacki later proposed a biological classification based on endothelial cell characteristics and clinical behavior, distinguishing hemangiomas from vascular malformations. The 2014 ISSVA classification further standardized terminology and divided lesions into hemangiomas, slow flow vascular malformations, fast flow vascular malformations, and complex combined malformations. The key differences are that hemangiomas are true tumors involving endothelial cell proliferation, while vascular malformations are malformed vessels present at birth that grow proportionately with the patient.
Vascular Lesions of the Brain

Hemorrhagic strokes ,Subarachnoid and Intrracerebral
CT and MRI are useful in detecting subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH). CT can detect SAH within 72 hours and locate the aneurysm. MRI is sensitive to subarachnoid blood within 12 hours. Fundus examination may reveal sub-hyaloid hemorrhage in 11-33% of SAH cases. ECG changes in SAH include prolonged QRS and T waves similar to cardiac ischemia. ICH causes include hypertension, anticoagulation, and vascular abnormalities. CT and MRI are used to diagnose ICH. Treatment depends on size and location but may include surgery or medical management.
Non traumatic haemorrhage
Intracranial haemorrhage can be intraaxial (within the brain substance) or extraaxial (outside the brain substance). Common causes of intraaxial haemorrhage include hypertension, amyloid angiopathy, cavernous angiomas, and tumours. Extraaxial haemorrhages include subdural, subarachnoid and epidural haemorrhages. MRI appearance of haemorrhage depends on the breakdown products of haemoglobin at different stages. Imaging helps to characterise the haemorrhage and identify its cause.
Sub-Arachnoid Hemorrhage
Subarachnoid hemorrhage is caused most commonly by the rupture of a saccular aneurysm. The rupture causes blood to fill the subarachnoid space, which can lead to neurological deficits or death. Treatment involves securing the aneurysm through surgical clipping or endovascular coiling to prevent rebleeding, as well as managing complications like vasospasm, hydrocephalus, and seizures. Outcomes depend on the grade and location of the initial bleed and development of delayed cerebral ischemia.
Vascular malformations of brain.pptx
This document discusses various types of vascular malformations of the brain. It begins by describing the histopathology and classification of arteriovenous malformations (AVMs), venous angiomas, capillary telangiectasias, and cavernous malformations. It then covers the pathology, clinical features, diagnosis using angiography, and treatment options for AVMs including surgery, radiosurgery, and endovascular embolization. It also discusses dural arteriovenous fistulas, carotid cavernous fistulas, vein of Galen malformations, developmental venous anomalies, cavernous malformations, capillary telangiectasias, and sinus pericranii.
Cardiac tumors
1. Myxomas are the most common primary cardiac tumor, usually occurring in the left atrium and presenting with signs and symptoms similar to mitral valve disease like dyspnea and murmurs.
2. Other common benign tumors include rhabdomyomas in children and lipomas, while sarcomas are the most common malignant cardiac tumors in adults presenting with rapid progression.
3. Metastatic tumors to the heart are more common than primary cardiac tumors, usually from melanoma and lung/breast cancers through hematogenous spread.

ich.pptx
This document discusses the imaging approach for acute non-traumatic intracranial hemorrhage. It describes two main types: subarachnoid hemorrhage and intraparenchymal hemorrhage. For subarachnoid hemorrhage, CT is the best initial test and can identify over 98% of cases by detecting blood in the subarachnoid spaces. Aneurysms are the most common cause, found in 85% of cases using CTA. Intraparenchymal hemorrhages are most often due to hypertension but can also be caused by amyloid angiopathy, vascular malformations, tumors, or coagulopathies. CT and MRI are used to diagnose and identify
Intracranial vascular malformations
This document discusses imaging findings and classifications of various types of intra-cranial vascular malformations. It describes key features of arteriovenous malformations (AVMs), cerebral proliferative angiopathy, and dural arteriovenous fistulas (dAVFs). AVMs appear on imaging as a tightly packed tangle of vessels with early draining veins. Cerebral proliferative angiopathy presents as a diffuse network of vessels interspersed with normal brain tissue. DAVFs involve abnormal shunting between meningeal arteries and dural venous sinuses.
Arteriovenous Malformations
1. Arteriovenous malformations are congenital vascular anomalies resulting from arrested development between the arterial and venous systems, commonly presenting as masses, birthmarks, or limb swelling.
2. They are classified by the International Society for Vascular Anomalies into several types including venous, arteriovenous, arterial and lymphatic malformations.
3. Clinical presentation and management varies depending on the type of malformation, with venous malformations being the most common and arteriovenous malformations potentially the most serious if left untreated due to risks of bleeding, ischemia and high output heart failure.
