1. Venous malformations: congenital venous anomalies pathologically characterised by anomalous veins (thickened and hyalinised walls) separated by normal brain. These anatomically abnormal veins drain normal brain tissue. It is thought that they result from intrauterine ischemic event occurring during the formation of medullary veins resulting in collateral venous drainage. This is the most com...

PURPOSE To characterize the MR appearance of the common hemangioma of infancy as well as low- and high-flow vascular malformations of the head and neck. PATIENTS AND METHODS Twenty patients with vascular lesions of the head and neck proved either by pathology, angiography, and/or unequivocal clinical diagnosis were included. Vascular lesions included 15 low-flow lesions (four hemangiomas, 10 ...

Nasal arterio-venous malformations (AVM) are uncommon lesions. We present a rare case of huge, long standing AVM in the nasal area which was treated by angioembolization, followed by surgical excision and forehead flap reconstruction.

The communication between pulmonary artery and pulmonary vein or between a bronchial artery and the pulmonary vein is called as pulmonary arterio-venous malformation. Dyspnea on exertion, fatigue, nasal bleeding, bluish discoloration of lips and nail beds and hemoptysis are common presenting complaints. In childhood only 10% of cases are identified. Cerebral vascular accidents, brain abscess, h...

Cerebrovascular abnormalities are extremely complex, due to the multitude of factors acting simultaneously on cerebral hemodynamics. Cerebral Arterio Venous Malformation (CAVM) hemodynamic in one of the vascular abnormality condition results changes in the flow and pressure level in blood vessels. This can cause rupture or decreased blood supply to the tissue through capillary causing infarct. ...

BACKGROUND Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. CASE PRESENTATION Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out other...

Vascular anomalies are a diverse group of related conditions that include vascular tumors (hemangiomas) and vascular malformations (capillary malformations, venous malformations, lymphatic malformations and arteriovenous malformations). In the past decade or so, research has revealed the genetic or molecular basis for some of these lesions. We now know that a number of hereditary vascular malfo...

We report the utility of fluorescent indocyanine green (ICG) during the microsurgical resection of a giant perimedullary cervical arteriovenous fistula (GPMAVF) in a young man with hereditary hemorrhagic telangiectasia. ICG angiography is a useful adjunct for understanding angioarchitecture and drainage patterns in spinal arteriovenous malformation (AVM) surgery. Cervical GPMAVF is a rare spina...
