Gurugram, Nov. 21 -- A 16-year-old girl diagnosed with a rare congenital vascular disorder called arteriovenous malformation (AVM) was recently treated using a minimally invasive technique in Gurugram. In this disorder, arteries connect directly to veins without capillaries, causing pain and swelling. The girl suffering from peripheral vascular lesions in her right buttock was treated using a technique involving ethylene-vinyl alcohol copolymer (EVOH) -a liquid embolic agent typically used for complicated neurovascular procedures. Medanta Medicity doctors said the case highlights the expanding role of image-guided interventions in managing high-flow AVMs, especially during high-risk surgeries. "Such AVMs may remain silent for years but can enlarge with age, causing pain, tissue damage, functional impairment, or life-threatening bleeding in case a vessel ruptures," said Dr. Rajiv Parakh, chairman of Peripheral Vascular and Endovascular Sciences, Medanta Gurugram. EVOH is an embolic agent, which offers deep penetration into the core of AVM. "Unlike earlier techniques, the peripheral EVOH vial enabled occlusion of the AVM in a single procedure," said Dr Virender Sheorain, another vascular surgeon....
