[Problems arising in connection with surgical management of renovascular hypertension (author's transl)].

65 consecutive renal artery stenosis reconstructions for the treatment of severe renovascular hypertension are reported. 63% of the cases were males, 37% females. The disease was caused by arteriosclerosis in 66% of cases and in 23% by fibromuscular dysplasia or other pathological changes of the renal artery; the mean age was 47 in the former. and 31 years in the latter group. An aortorenal saphenous vein bypass was performed in 35% cases, a dacron graft was used in 29% and thrombendarteriectomy was carried out in 23% cases. Positive results were achieved in 68.8% of the patients. 63% of the females became normotensive. Operative mortality due to faulty technique was 4.9% initially. The operative mortality has been zero since 1973. nor have there been any therapeutic failures on a technical basis. No significant correlation was established between age of the patients and result of operation.
