Endovascular Management of Spontaneous Superficial Femoral Artery Pseudoaneurysm in a Renal Allograft Patient

ABSTRACT

We report a case of a superficial femoral artery pseudoaneurysm in 52-year old patient with a history of having renal allograft. The pseudoaneurysm spontaneously developed while standing up from squatting position after defecation, and it was successfully managed by an endovascular repair with an endograft. This case suggests that an atherosclerotic superficial femoral artery is vulnerable to torsion and tension movement during changing position from squatting to standing, which is repeatedly practiced by the people using the Korean traditional toilet. The endovascular therapy is also recommended for elderly patients with poor clinical conditions such as having a renal allograft and diffuse atherosclerosis of peripheral arteries.
