Anterior Tibial Artery Pseudoaneurysm as a Complication of Anterior Ankle Arthroscopy: A Case Report

Keywords: Pseudoaneurysm, arthroscopy, ankle

Abstract

We present the case of an anterior tibial artery pseudoaneurysm as a complication following anterior ankle arthroscopy. This complication is extremely rare and represents a therapeutic challenge. A patient developed progressively worsening pain, limited dorsiflexion, local swelling, and gait claudication two weeks after undergoing anterior ankle arthroscopy for anterior impingement syndrome and an osteochondral lesion, without signs or symptoms of infection. Magnetic resonance imaging (MRI) and ultrasound established the diagnosis of an anterior tibial artery pseudoaneurysm. Treatment consisted of thrombin injection followed by microcoil embolization under angiographic guidance. The outcome was favorable, with resolution of pain, successful treatment of the pseudoaneurysm, and recovery of ankle mobility. Conclusions: Clinical suspicion is essential in patients presenting with disproportionate pain, swelling, or a pulsatile mass. Early diagnosis and treatment are associated with a better prognosis.
