Pseudoaneurysm of the dorsalis pedis artery after ankle arthroscopy.

Arthroscopic ankle synovectomy is believed to be associated with few complications. Vascular complications are rare, and we describe a case of iatrogenic pseudoaneursym formation of the dorsalis pedis artery (DPA) after ankle arthroscopy, using standard anteromedial and anterolateral ports, which has not been, we believe, previously reported in the literature. This rare complication required surgical exploration and ligation, and the patient had an uneventful recovery.
