The minimally invasive management of visceral artery aneurysms and pseudoaneurysms

ObjectiveMinimally invasive methods (MIMs) are now available for the management of visceral artery aneurysms and pseudoaneurysms (visceral artery aneurysms [VAA]). The purpose of this study was to review our 10-year experience with the MIM of treating VAA.MethodsAll patients evaluated from June 1999 to June 2009 with VAAs were reviewed. Demographics, therapy, and results were analyzed.ResultsMIM was attempted in 185 aneurysms in 176 patients. Initial intervention was successful in 98% ofaneurysms. Sixty-three (34%) aneurysms were located in the splenic artery, 56 (30%) in the hepatic, 28 (15%) in the gastroduodenal, 16 (8.6%) in the pancreaticoduodenal, six (3.2%) in the superior mesenteric, four (2.1%) in the gastric, four (2.1%) in the celiac, four (2.1%) in the gastroepiploic, two (1%) in the inferior mesenteric, and one (0.5%) in the middle colic artery. Pseudoaneurysms were more common than true aneurysms (64% vs 36%). Bleeding was the indication for intervention in 86 aneurysms (46%). Initial treatment was successful in 177 aneurysms (98%). Reintervention was required in five (3%) aneurysms within 30 days. Coiling was used alone in 139 aneurysms (75%) and in combination with at least one other technique in 20 (11%) cases. Thirty-day aneurysm-related mortality was 3.4% (six deaths). Five additional deaths occurred during 30-day follow-up, although none was related to complications of the aneurysms (2.8%).ConclusionsMIM for visceral artery aneurysms can be used alone or in combination to effectively treat VAAs in elective or emergent conditions
