Late failure of endovascular repair of an isolated true aneurysm of the profunda femoris artery

Isolated profunda femoris artery aneurysms (PFAAs) are rare among all peripheral artery aneurysms. True PFAAs are often associated with atherosclerosis, whereas PFA pseudoaneurysms are related to trauma. The optimal treatment for PFAAs is unclear, but a variety of methods have been used, such as open resection with or without revascularization, stent graft placement, and coil embolization. We present an interesting case of a PFAA initially treated with endovascular means with a late failure requiring open surgery nearly 3 years after the initial treatment.
