Arteriomegaly: classification and morbid implications of diffuse aneurysmal disease.

Ninety-one patients with arteriomegaly and diffuse aneurysmal disease below the level of the renal arteries have been classified according to the extent and location of aneurysmal change. There exists a high incidence of thrombotic and embolic complications, and treatment entails increased rates of morbidity and mortality when compared to surgical treatment of simple abdominal aneurysms of peripheral artery aneurysms. Complete revascularization at the initial operation would appear to give the best result, but this approach must be tempered by the individual patient risk factors and the urgency of the mode of presentation of the patient.
