A Case of an Aneurysm of the Superficial Femoral Artery Affected with Kawasaki Disease

Abstract

A 6-year-old woman complained of painful mass in her left thigh. She had a history of Kawasaki disease at the age of 5. Contrast-enhanced CT scan showed a 33 mm aneurysm in the left superficial femoral artery. There was no coronary aneurysm or any other peripheral aneurysm. We resected the aneurysm and performed a vascular reconstruction procedure using the great saphenous vein. Pathological examination of the aneurysmal wall showed severe edematous and myxomatous thickening of the arterial tunica media and partial destruction of the tunica media with inflammatory cell infiltration. Kawasaki disease is well known for its coronary artery lesions, but peripheral aneurysms are uncommon, especially aneurysms of the superficial femoral artery, which have not been reported.
