Successful laparoscopic arterial ligation of splenic artery aneurysm with a splenomesenteric trunk: a case report and literature review.

Background: The mortality rate of splenic artery aneurysm rupture is very high, and patients with aneurysms larger than 30 mm are recommended for treatment, regardless of the presence or absence of symptoms. We herein report a case of splenic artery aneurysm with an abnormal bifurcation that was treated with laparoscopic ligation of the splenic artery.

Case Presentation: A 51 year-old Japanese male was referred to our hospital because a splenic artery aneurysm was noted on abdominal echocardiography during a medical examination.
