Visceral aneurysms are rare in the general population (<2%), and the most serious complication is represented by aneurysm rupture. The use of stent grafts to exclude visceral aneurysms is described in several reports but is reserved for patients with favorable anatomy. We report here on a hepatic artery pseudoaneurysm in a liver transplant patient and a patient with an aneurysmal vein graft degeneration of a renal bypass, both with no suitable proximal neck for standard stent grafting. Both patients were successfully treated with a custom-made aortic endograft with a single fenestration for the hepatic or renal artery, together with a visceral covered stent. Although initial results are promising, long-term follow-up is required to assess durability.

Abstract
Visceral aneurysms are rare in the general population (<2%), and the most serious complication is represented by aneurysm rupture. The use of stent grafts to exclude visceral aneurysms is described in several reports but is reserved for patients with favorable anatomy. We report here on a hepatic artery pseudoaneurysm in a liver transplant patient and a patient with an aneurysmal vein graft degeneration of a renal bypass, both with no suitable proximal neck for standard stent grafting. Both patients were successfully treated with a custom-made aortic endograft with a single fenestration for the hepatic or renal artery, together with a visceral covered stent. Although initial results are promising, long-term follow-up is required to assess durability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
