Nonsurgical treatment of cystic adventitial disease of the popliteal artery caused by functional popliteal artery entrapment syndrome

Abstract

Lower extremity claudication in young men can be caused by popliteal artery entrapment and vascular pathology. The case reported here describes a young male wrestler who presented with unilateral calf pain with activity. Imaging studies at rest demonstrated cystic adventitial disease of the popliteal artery. Stress imaging showed severe functional popliteal artery entrapment. This patient was treated with an imaging-guided botulinum toxin injection of the muscles at the site of arterial compression. The patient was asymptomatic 6 weeks after treatment. Repeat stress imaging demonstrated complete resolution of the entrapment and nearly complete resolution of the popliteal artery cystic adventitial disease.
