Visceral Artery Aneurysms: Alternative Therapeutic Approach

The authors report two cases in which stent grafts were used to treat visceral artery aneurysms. Case number 1 was a 42-year old woman with a history of renal colic who was found to have a right renal artery aneurysm. Two 6-mm x 20-mm Wallgraft endoprosthesis (Boston Scientific, Watertown, Mass) were placed across the aneurysm neck. Case number 2 was a 72 year-old woman with a past medical history significant for hepatic angioma and hypothyroidism. She was found to have a superior mesenteric artery aneurysm that was treated with a 6-mm x 17-mm Jostent stent graft (Jomed, GmbH, Ra). In both cases the aneurysm was completely excluded and distal end-organ flow preserved. Stent graft placement is a safe and effective treatment for visceral artery aneurysms. If this approach proves durable and reproducible, it can become the method of choice for the management of visceral artery aneurysms in selected patients
