Common iliac artery aneurysm due to fibromuscular dysplasia in infants

Abstract

A seven-month old female with a huge aneurysm of the right common iliac artery and multiple stenoses of her bilateral renal arteries is described. At surgery, a Gore-Tex graft was interposed between the proximal common iliac artery and the external iliac artery. A histological examination of the aneurysmal wall was compatible with medial fibromuscular dysplasia (FMD). After surgery, her blood pressure was controlled in the normal range on medical treatment. This case would be the first case of a huge common iliac artery aneurysm due to FMD in infants.
