[Successful deployment of a stent graft in the popliteal artery for pseudoaneurysm after acupuncture: a case report].

A 71-year-old man was admitted to our hospital because of swelling and pain in his right calf developing after acupuncture for intermittent claudication. Computed tomography with contrast medium revealed a large hematoma with contrast medium leakage in his right calf. Emergent angiography demonstrated a pseudoaneurysm of the right popliteal artery with severe stenosis. Intravascular ultrasound showed lumen narrowing with a large amount of concentric plaque and disruption of the vessel wall communicating to a large cavity outside. A polytetrafluoroethylene-covered Jostent graft was deployed into the stenotic lesion across the opening into the pseudoaneurysm cavity. Subsequent angiography showed no leakage of contrast medium. This unique case of pseudoaneurysm caused by acupuncture in the popliteal artery was treated successfully by endovascular repair.
