Endovascular management in abdominal visceral arterial aneurysms: A pictorial essay

Visceral artery aneurysms (VAAs) include aneurysms of the splanchnic circulation and those of the renal artery. Their diagnosis is clinically important because of the associated high mortality and potential complications. Splenic, superior mesenteric, gastroduodenal, hepatic and renal arteries are some of the common arteries affected by VAAs. Though surgical resection and anastomosis still remains the treatment of choice in some of the cases, especially cases involving the proximal arteries, increasingly endovascular treatment is being used for more distal vessels. We present a pictorial review of various intra-abdominal VAAs and their endovascular management. (C) 2011 Baishideng. All rights reserved.
