Pseudoaneurysm as a complication of ankle arthroscopy

We describe a case of pseudoaneurysm of the anterior tibial artery as a com plication after arthroscopic ankle synovectomy, in which standard anterolat eral and anteromedial portals were used. Pseudoaneurysm has been previously reported as a complication in ankle arthroscopy with the use of the antero central portal. Previously described anatomic variations of the tibial arte ry and its close relationship with the anterior ankle capsule may complicat e arthroscopic surgery, especially when aggressive synovectomy is performed . Anterior tibial artery aneurysm is a rare complication of ankle arthrosco py, but its potential catastrophic sequelas must not be underestimated.
