Hypoplasia of the abdominal aorta

A case of a 10 year old girl with hypoplasia of the inter-reno-mesenteric region of the abdominal aorta, which was accompanied by other pathological entities, is reported. The classification, etiology, clinical manifestations and diagnosis is discussed in detail. Successful treatment was accomplished with aorto-aortic bypass grafting and additional saphenous vein bypass from the aorta to the right renal artery. The conclusion of this study is that the hypoplasia of the abdominal aorta is a rare disease which may affect beyond the confines of the aorta and may involve the origins of vital arteries. Surgery offers the only chance of a favourable outcome.
