Revascularization of totally occluded renal arteries.

Two cases of total renal artery occlusion are presented. The clinical durations of occlusion were 10 days and 6 months. Revascularization procedures were successful in both patients, resulting in return of renal function and alleviation of hypertension. Our 2 cases and a review of 30 other cases demonstrate that the maximum duration of main renal artery occlusion with subsequent return of renal function is unknown.
