Iatrogenic injury to the descending branch of the lateral circumflex femoral artery during intertrochanteric fracture fixation: a case report of guide pin-related vascular complication

Vascular injuries associated with femoral intertrochanteric fractures are rare but can result in serious complications. A case of iatrogenic injury to the descending branch of the lateral circumflex femoral artery in a patient who underwent surgical fixation of an intertro-chanteric femoral fracture is presented. The injury possibly occurred during the creation of the entry point for nail insertion using a guide pin. Clinical symptoms emerged 10 days postoperatively and were successfully managed with percutaneous embolization, without major complications. This case highlights that pseudoaneurysms can develop as a result of guide pin use during hip nailing procedures. Surgeons can avoid this complication by obtaining lateral and anteroposterior views of the hip.
