Delayed presentation of superficial femoral artery pseudoaneurysm 45 years following gunshot injury

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

“…The cause of injury is different in each published case. The postulated mechanisms were an injury to the arterial wall by fractured edges of bone before or after fixation [4,7], concussion due to high velocity projectile gunshot injuries or mortar fragment injuries [1,2,6], and penetrating trauma causing direct injury to the artery [3,5].In this case, the possible mechanism of injury would be the high-velocity trauma which caused the distal femur fracture or the jagged edges before fixation. The injury is unlikely to be associated with lag screw fixation or external fixators as they were placed well laterally as the neck of the pseudoaneurysm was present anteromedially.…”

“…Selection of the management option depends on the size, site of the aneurysm, presence of signs and symptoms and the available resources. Out of the few published cases, two were treated with surgical repair and venous patch angioplasty [1,3], two with endovascular stent placement [2,4], two with aneurysmal repair and feeding vessel ligation [5,7] and one with vascular reconstruction with reversed venous graft [6]. The outcome of all the cases was reported as good.…”

“…Delayed presentation of posttraumatic superficial femoral artery (SFA) pseudo aneurysm is a rare manifestation. Only a few cases have been published in the literature [1][2][3][4][5][6][7]. A literature search was done on Pubmed and google scholar using the search terms 'delayed presentation', 'pseudo aneurysm', 'false aneurysm', 'post trauma' and 'superficial femoral artery'.…”
