Vascular complications following internal fixation of trochanteric femoral fractures are extremely rare. Iatrogenic injury to the profunda femoris artery or one of its branches and resultant pseudoaneurysm formation has been documented, most commonly following sliding hip screw fixation and typically arises on the posteromedial aspect of the femur. We report an unusual variation, following proximal femoral nailing of an intertrochanteric femoral neck fracture, where the pseudoaneurysm presented four weeks following surgery on the posterolateral aspect of the femur. The mechanism of injury, clinical presentation and potential preventative measures are discussed.
股骨转子间骨折内固定术后的血管并发症极为罕见。医源性损伤股深动脉或其分支之一并导致假性动脉瘤形成已有文献记载，最常见于动力髋螺钉固定后，且通常发生在股骨后内侧。我们报告了一例不寻常的情况，在股骨近端髓内钉治疗股骨转子间骨折后，假性动脉瘤在术后四周出现在股骨后外侧。本文讨论了损伤机制、临床表现及潜在的预防措施。
