Renal function following aortic surgery.

Following aortic surgery nearly two thirds of patients (65%) have demonstrable renal tubular damage, which is related to the disease process (aneurysmal disease being more commonly associated with renal damage than occlusive disease), the duration of aortic cross clamping and the volume of blood transfused. No relationship appears to exist between age, pre-operative hypertension, or chronic renal failure, and post operative renal tubular function.
