Delayed presentation of superficial femoral artery (SFA) pseudo aneurysm three month following trauma

This case report describes a rare delayed presentation of posttraumatic pseudoaneurysm of superficial femoral artery (SFA). A 22-year-old man presented with a painful expanding mass over the anteromedial aspect of the distal thigh three months after a motor traffic crash. The lump was tender and pulsatile on examination. CT angiogram revealed a pseudoaneurysm of distal SFA. Open surgical repair was done and the recovery was uneventful. It is to emphasize that absence of physical signs of vascular injury on immediate assessment following trauma does not exclude vascular injury and it can manifest as pseudoaneurysms even after months.
