Extracorporeal repair of the renal artery for renovascular hypertension: a case report.

A case of successful correction of renovascular hypertension by means of extracorporeal repair of fibroplasia of the main trunk and an aneurysm of a secondary division branch of the left renal artery is presented. The ureter was not transected and a segment of the internal ilac artery with two branches was used for the substitution of the diseased renal artery segments. The kidney was preserved by intermittent flushing with iced Ringer's lactate solution. A probable post-operative arterial thrombosis of the repaired secondary branch was successfully treated with intravenous streptokinase. One year after the operation the patient is normotensive.
