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

Abstract

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.

“…Causes of pseudoaneurysm include infection, trauma, iatrogenic causes, Behcet's disease, Ehlers–Danlos syndrome (Type IV), and other connective tissue disorders. 1 Spontaneous onset of superficial femoral artery pseudoaneurysm is rare 2 and thought to be caused by atherosclerosis. 3 In this case, there was no evidence of atherosclerosis in the superficial femoral artery, which was in good condition.…”

Delayed Presentation of Non-traumatic Bilateral Leg Pseudoaneurysms Mimicking Soft-Tissue Sarcoma – A Case Report

“…There are only a very limited number of cases published in the literature with spontaneous SFA artery pseudoaneurysms and rupture is yet more rare [ 6 ]. There are case reports though of femoral artery pseudoaneurysm – but with the exception of the limited cases mentioned above – they clearly document a traumatic blunt trauma [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

Spontaneous bilateral superficial femoral artery pseudoaneurysms and a unilateral posterior tibial artery aneurysm in an immunocompromised patient

“…Pseudoaneurysms are most commonly a result of trauma but can also be iatrogenic during catheterization of vessels, vessel instrumentation, at anastomotic sites or due to failure of percutaneous closure devices 1 . Spontaneous superficial femoral artery (SFA) pseudoaneurysms are rare, but have been reported to be associated with infection, vasculitides, and connective tissue disorders 2 …”

“…1 Spontaneous superficial femoral artery (SFA) pseudoaneurysms are rare, but have been reported to be associated with infection, vasculitides, and connective tissue disorders. 2 We present this unique case where the SFA pseudoaneurysms, were bilateral, spontaneous, without any obvious infective cause with an associated synchronous saccular aneurysm of the left posterior tibial artery (PTA), which together has not been reported as a case in the literature to date.…”
