Abstract

Nephrectomy and revascularization are currently the preferred options in the management of the chronically occluded renal artery in patients with renovascular hypertension or renal insufficiency. We review our experience with these two options including early and late functional outcome. Between December 1982 and August 1993, chronic occlusion of the main renal artery was documented in 30 patients. Patients were categorized with respect to surgical intervention: group I underwent nephrectomy (on the occluded side) plus contralateral revascularization and group II underwent revascularization of the occluded renal artery. The median age at the time of operative intervention was 63 years; 53% of the patients were women and 47% were men. Hypertension was poorly controlled (>-3 medications) in 19 patients, and the preoperative serum creatinine level was > 1.8 mg/dl in 24 patients (mean 2.6±1.4 mg/dl). There were 16 patients in group I and 14 patients in group II, and there were no perioperative deaths. Estimated glomerular filtration rate (>-7 days after operation) was either unchanged or improved in 15 of 16 patients in group I and in 13 of 14 in group II, one of whom became dialysis dependent. Follow-up data were available for 25 of 30 (83%) patients (mean 45 months; range 1 to 108 months). Excluding one early failure, 10 of 13 patients in group I and 7 of 11 in group II did not have end-stage renal disease at last follow-up. Overall, hypertension was cured or improved in 16 of 21 patients. Revascularization as the preferred method of treatment of the occluded renal artery offers the prospect of renal salvage. Nonetheless, in the majority of properly selected patients, adequate renal function may be sustained and satisfactory blood pressure control achieved after nephrectomy with contralateral revascularization.
