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...

Hereditary Haemorrhagic Telangiectasia (HHT) is an autosomal dominant disorder characterized by vascular dysplasia. Hepatic Vascular Malformations (VMs) range from small telangiectases to significant shunting. Here we report two cases of HHT. Case 1 had diffuse ectasia the hepatic artery along its intrahepatic and extrahepatic course with a arterial aneurysm. 2 presented ileal telangiectases. K...

Background: Arteriovenous malformations are one of the most common vascular disorders of the colon. Vascular disorders present as painless, high-volume rectal bleeding. Case Presentation: This study elucidates two rare cases of vascular disorders that are diagnosed as angiodysplasia of the left colon and cavernous hemangioma of the colon and rectum.  The chief complaint in two patients ...

developmental venous anomaly (dva) is a common lesion formerly known as venous angioma. dvas drain normal brain parenchyma; however, parenchymal abnormalities surrounding dvas have been reported. unilateral putamen and caudate calcification in the drainage territory of dvas has so far been reported in 7 cases, all with deep venous drainage. we present two additional cases of dvas, one with supe...

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...

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 ...

pulmonary arteriovenous malformations (avms) are rare vascular malformations of the lung that usually led to a notable risk of serious and life-threatening complications. there is considerable debate about the best management of strategies for the group of patients with diffuse avms. several therapeutic options have been reported for management of this abnormality among which coil embolization ...
