Vascular obstruction at the level of the ankle joint as a complication of hip arthroscopy.

Abstract
We report a case of foot vascular obstruction as a complication of hip arthroscopy. A 23-year-old female patient underwent hip arthroscopy for femoroacetabular impingement. The duration of the procedure was 80 minutes, including 20 minutes with traction for arthroscopy of the central compartment and 60 minutes without traction for cam treatment in the peripheral compartment. Three days postoperatively, the patient complained of a cold foot and pain and paresthesia during leg and foot elevation with continuous passive motion therapy. With persisting symptoms, she was seen by the referring physician 4 days postoperatively. Pulselessness at the level of the ankle and reduced capillary perfusion were observed. Doppler sonography and magnetic resonance angiography showed an occlusion of the peroneal, posterior tibial, and anterior tibial arteries at the level of the right ankle. The patient was readmitted to the hospital and underwent intravenous prostaglandin E1 therapy for 9 days, followed by oral clopidogrel treatment for 6 weeks. After 8 weeks, follow-up Doppler sonographic findings were normal. Subjective paresthesia and sensation of coldness resolved completely after 6 months. Possible theories for this complication and strategies on how to avoid it are discussed.
