title: Recurrent splenic artery aneurysms developing after aneurysmectomy without splenectomy: report of a case.
abstract: We report herein the case of a 47-year-old man who developed a huge splenic artery aneurysm (SAA) with splenomegaly, for which ligation of the splenic artery and partial aneurysmectomy was performed. A celiac arteriogram taken 2 months postoperatively revealed that two small aneurysms had developed in the collateral vessels, indicating that increased blood flow through the collateral circulation could be responsible for the formation of secondary aneurysms. This postoperative change suggests that the etiology is related to the SAA and thus, the possibility that aneurysms may develop in the collateral vessels following spleen-preserving procedures for SAA must be borne in mind and careful follow-up performed at regular intervals.
