[Renal artery occlusion. Blood pressure and kidney function before and after surgical treatment]

Angioplasty was performed in 16 patients with renal artery occlusion. It was successful in each of six acute occlusions, although four patients died later of their underlying disease. Two patients are long-term survivors and have normal or compensated renal function up to three years postoperatively. Vessel reconstruction was successful in eight of ten patients with chronic occlusion. In seven there was definite improvement or normalization of the hypertension, in six renal function returned to normal. Thus the success rate as to organ preservation with improvement in pressure and function was 60%.
