A rare case of spontaneous superficial femoral artery pseudoaneurysm in a young patient: case report and review of literature.

Spontaneous femoral artery pseudoaneurysm (PSA) is a rare disease and there are few reported cases. We report a case of a 17-year-old male with increasing left leg pain associated with swelling at the site of the pain. We observed a voluminous pulsatile mass. He had no history of trauma or surgery. Imaging confirmed a large PSA of the proximal portion of the left superficial femoral artery (SFA). The PSA was treated by resection of the aneurysm, reconstruction with inter-positional saphenous vein graft. Three months later; he came back to the emergency room for a pulsatile mass. The scan showed a PSA of his left SFA and a hematoma with active bleeding. It was treated surgically by resection of the aneurysm and reconstruction with graft.
