Spontaneous and isolated dissection of the external iliac artery: a case report.

Spontaneous and isolated dissection of the limb arteries without involvement of the aorta is extremely rare. We present a 36-year-old male who has 95% tapering stenosis and dissection of the left external iliac artery with abrupt onset with total thrombosis in the false lumen until the level of the inguinal ligament. We also suggest that endovascular stent graft placement is a useful treatment for isolated arterial dissections prior to operation in consideration of the technical ease and safety of guiding intravascular ultrasound like in this case.
