A Case of Persistent Sciatic Artery Aneurysm with Distal Embolization Treated by Endovascular Treatment

Abstract

A 79 year-old female with left buttock and thigh pain was diagnosed as persistent sciatic artery aneurysm (PSAA) by CT. On the following day she had her left lower limb pain caused by embolic ischemia. Distal embolization was treated by transcatheter thrombus suction and thrombolytic therapy. A Viabahn (W.L. Gore, AZ, USA) was deployed to exclude the PSAA. Although the lower limb pain was alleviated, the stent graft occluded in the early postoperative period and caused intermittent claudication. As the long term results of stent graft placement for persistent sciatic artery is unknown, the indication should be carefully considered.
