 We report a case of splenic artery aneurysm which was treated laparoscopically. A 51 year-old male patient was diagnosed with a splenic artery aneurysm at the splenic hilum by computed tomography(CT) for lung cancer screening. The aneurysm measured 50mm in diameter. Preoperative angiography estimated 40% splenic infarction by embolization of the aneurysm; thus, resection of the aneurysm accompanied by splenectomy was scheduled. To prevent rupture of the aneurysm, we planned to resect the left gastroepiploic artery, short gastric arteries and posterior gastric artery firstly, then the splenic artery prior to mobilization of the spleen. Based on the CT findings, we planned to dissect the splenic artery at the pancreas body firstly, and then, close to the aneurysm. The operation was performed with 4 trocars. The operation was completed by resecting the splenic vein. This is the biggest splenic artery aneurysm resected laparoscopically in Japan. Laparoscopic resection of splenic artery aneurysms can be performed safely by devascularizing aneurysmal inflow prior to mobilization of the spleen.
