Abstract
Pseudoaneurysm of the profunda femoris artery (PFA) is a rare but potentially serious complication of total hip arthroplasty (THA). Due to the atypical symptoms, diagnosis and treatment are often delayed. The direct anterior approach (DAA) for THA has grown increasingly popular, largely owing to its minimally invasive advantages. Here, we present two cases of pseudoaneurysm involving perforating branches of the PFA following DAA-THA. The first case underwent a tortuous diagnostic process, ultimately resolved by digital subtraction angiography (DSA)-guided open vascular ligation. In contrast, the second case was successfully treated with endovascular embolization immediately after DSA confirmation.
