Developmental arteriovenous malformation with secondary angiodermatitis. Report of a case

Radiation therapy for intractable bleeding in extremity arteriovenous malformation: Considerations on a clinical case

“…5 These evolutive vascular formations rarely appear before adolescence and may not be evident until additional growth or vascular engorgement manifests as a response to thrombosis, trauma, infection or endocrine fluctuations. 11,12 Some vascular malformations appear as part of a familial genetic disorder called angiomatous syndrome (Rendu-Osler-Weber syndrome, which usually manifests with telangiectasia of the skin and mucous membranes.…”

“…Vascular malformations occur as a consequence of anomalous congenital vascular abnormalities and aberrant vessel angiogenesis comprising direct microscopic connections between arteries, veins and lymphatic vessels without the normal capillary bed 5 . These evolutive vascular formations rarely appear before adolescence and may not be evident until additional growth or vascular engorgement manifests as a response to thrombosis, trauma, infection or endocrine fluctuations 11,12 . Some vascular malformations appear as part of a familial genetic disorder called angiomatous syndrome (Rendu–Osler–Weber syndrome, which usually manifests with telangiectasia of the skin and mucous membranes.…”

Prevention of a Foot Amputation: A Large Arteriovenous Malformation Reconstructed with a Composite Free Flap

“…In the patient presented in this article, a bruit or thrill was not observed because, in arteriovenous malformations of the extremities, the flow is usually through multiple small communications, as other investigators have proposed. 6 Arteriovenous malformations located in the extremities are not believed to shunt enough blood to have a significant effect on the cardiac Volume 119, Number 5 • Vascular Malformation in the Foot system. However, distal shunting has the propensity to significantly reduce the flow rate beyond the shunt and thus induce peripheral ischemia.…”

En bloc Surgical Excision of an Arteriovenous Malformation in the Foot: A Case Report and Review of the Literature

“…These lesions are low resistance and high flow vascular channels characterized by a central nidus of interconnected arteries and veins without an intermediate capillary network. Congenital maldevelopment is the most common cause of an AVM, although other causes including trauma have been reported [ 2 , 3 , 4 ]. These lesions are formed during fetal development as a result of an abnormal differentiation of the vascular structures.…”
