Abstract PDF: We report a case of iatrogenic injury to the lateral circumflex femoral artery following distal femoral nailing in a 72-year-old patient. Postoperatively, progressive thigh swelling developed, but initial contrast-enhanced computed tomography (CT) showed no evidence of vascular injury. The arterial injury was subsequently identified on a follow-up contrast-enhanced CT scan and was successfully treated with angiographic microcoil embolization. This case underscores the critical importance of meticulous awareness of the trajectories of the lateral circumflex and deep femoral arteries during proximal interlocking screw insertion. It also highlights that early postoperative imaging can fail to detect such vascular complications. Therefore, a high index of clinical suspicion is paramount, and repeated imaging should be strongly considered if clinical signs, such as progressive swelling, persist despite initial negative findings.; Summary
