Abstract
BackgroundPseudoaneurysm formation is rare complication after arthroscopy with incidence of 0.008%, easy to misdiagnose. Its potential catastrophic sequelae should not be underestimated.Case presentationWe present a case of missed diagnosis of traumatic anterior tibial artery pseudoaneurysm in a 39 years old female, instead treated as post operative arthroscopy infection. The diagnosis was confirmed with a duplex ultrasound scan and referred to the vascular surgeon with successful out come.ConclusionIn view of rare presentation this complication, it is easily missed. According to one study, incidence of anatomic variations of anterior tibial artery range from 2.4 to 12%. Because of this anatomical variation in course along with other factors, pseudoaneurysm formation at ankle is relatively high. In this report, we discuss the diagnosis, anatomical variations of anterior tibial artery and prevention of this complication following arthroscopy. We believe that surgeons operating in this region should take into account these anatomical variations preoperatively.

Anterior tibial artery pseudoaneurysm formation is a rare complication of ankle arthroscopy, with only six cases being described in the literature [1,2,3,4,5]
Summary
Pseudoaneurysm may present early or late in the postoperative period, and the clinician should be on the lookout for this rare potential complication to prevent missing this diagnosis. The surgeon should consider this rare complication as well as the anatomic variations of the artery when performing this procedure. Post operative ankle arthroscopy with not healing port wound and intermittent bleeding from port with or without osseous erosion of distal end of tibia, one should suspect pseudoaneurysm until proved otherwise. Written informed consent was obtained from the patient for publication of this case report and accompanying images.
