Avulsion injury to the profunda femoris artery after total hip arthroplasty.

Vascular injuries are a rare complication of total hip arthroplasty (THA). We describe the case of 71-year-old man who underwent an elective left THA and developed a pseudoaneurysm from an avulsion injury to the first branch of the profunda femoris artery. The patient underwent urgent open primary repair of the pseudoaneurysm and recovered without any complications. This case demonstrates the importance of assessing for vascular injuries after THA and of educating patients about the associated signs and symptoms.
