Traumatic aneurysms of the superficial femoral (SFA) and superior medial geniculate artery (SMGA) demonstrated late expansion of previously well contained hematomas which were pulsatile and remarkable for the presence of bruits. Injury to the SFA resulted in a cool, pulseless distal extremity. Direct exploration of the pseudoaneurysm cavity following proximal and distal control of the main arterial segment resulted in optimal exposure and successful repair of the arterial defect. Blunt trauma may result in pseudoaneurysm formation. Persistent swelling at a focus of injury despite normal distal pulsation is an early indicator of major vascular injury.
股浅动脉（SFA）和膝上内侧动脉（SMGA）的创伤性动脉瘤表现为先前局限良好的血肿出现晚期扩大，这些血肿有搏动且可闻及杂音。SFA损伤导致远端肢体发凉、无脉。在对主要动脉段进行近端和远端控制后，直接探查假性动脉瘤腔可实现最佳暴露并成功修复动脉缺损。钝性创伤可能导致假性动脉瘤形成。尽管远端搏动正常，但损伤部位持续肿胀是主要血管损伤的早期指标。
