Spine vascular lesions like brain include spinal cord stroke, malformation such as venous or angioma, cavernous malformation, arteriovenous fistula. Embryogenesis of is the basic principle to understand spine. This study aims report serial cases with review lesions. MR angiography techniques contrast injection may reflect direction flow epidural veins describe site arterial feeders. Serpiginous...

Vascular malformations are a disruption of the normal vascular pattern in which it is expected that a capillary network of microscopic vessels lies interposed between high-pressure arteries that deliver blood and thin-walled veins that collect low-pressure blood for return to the heart. In the case of arteriovenous malformations, arteries or arterioles connect directly to the venous collection ...

The Vascular lesions are indeed very widespread, with vascular tumors numbering the most common tumors in childhood. Researchers and authors frequently use the idiom hemangioma to portray or describe vascular malformations and a potpourri of vascular anomalies, whereas many of the others still use the term cavernous hemangioma for describing venous malformation and port-wine stain for capillary...

Congenital vascular malformation represents a group of anomalous vascular structures caused by defective development through various stages of embryogenesis. In 1988 a workshop for this unique field of vascular pathology was held in Hamburg, Germany, and new classification was evolved on the basis of consensus through this workshop. Congenital vascular malformations are now classified based on ...

Forty-three patients with cerebral vascular malformation were studied with precontrast, immediate contrast, and 1 hr delayed high dose contrast computed tomography (CT) scans. The precontrast scans were abnormal in 81% of patients. The delayed high dose scans demonstrated one angiographically occult, thrombosed arteriovenous malformation not seen on pre- or immediate contrast scans, four cases ...

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...
