Congenital-idiopathic superficial femoral artery aneurysm in a 7-year-old child

Abstract

Superficial femoral artery aneurysm in children is distinctly uncommon, and usually results from infection, vasculitis, connective tissue disorder, or trauma. We report a 7-year-old girl who had multiple fusiform aneurysms of the right superficial femoral artery, with no evidence of related disorders. The patient successfully underwent aneurysm resection and femoral artery reconstruction with autogenous saphenous vein. Histologic examination revealed intimal thickening with fibroplasia without severe inflammatory infiltrates or cystic medial necrosis, suggesting a congenital-idiopathic arterial aneurysm. Three years after the procedure, the saphenous vein graft is fully patent and the patient is in good condition.
