[Cause of failure in the surgery of renovascular hypertension].

The experience of 193 operations on 172 patients with affected renal arteries is described. The causes of failure in the surgery are analyzed. Organ-preserving operations with reconstruction of 189 renal arteries were performed on 136 patients. Primary nephrectomies were performed on 36 patients. During recent 3 years nephrectomies were made in 8% of 70 operations. Postoperative mortality was about 7%, mainly due to atherosclerotic patients. The main causes of uneffective operations are as follows: technical errors in revascularization of the kidney, pyelonephritis and neuroangiosclerosis non-diagnosed preoperatively, progressing lesions of the vessels in atherosclerosis and panarteritis.
