Bilateral popliteal arterial dissection.

A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery.
