Endovascular Treatment of Splenic Artery Aneurysm With a Stent-Graft: A Case Report

Splenic artery aneurysm, one of the most common visceral aneurysms, accounts for 60% of all visceral aneurysm cases. Open surgery is the traditional treatment for splenic artery aneurysm but has the disadvantages of serious surgical injuries, a high risk of complications, and a high mortality rate. We report a case who was presented with splenic artery aneurysm. A 54-year-old woman complained of upper left abdominal pain for 6 months. An enhanced computed tomography scan of the upper abdomen indicated the presence of splenic artery aneurysm. The splenic artery aneurysm was located under digital subtraction angiography and a 6/60 mm stent graft was delivered and released to cover the aneurysm. An enhanced computed tomography scan showed that the splenic artery aneurysm remained well separated, the stent graft shape was normal, and the blood flow was unobstructed after 1 year. This case indicates a satisfactory efficacy proving the minimal invasiveness of stent graft exclusion treatment for splenic artery aneurysm.
