Reconstructive vascular surgery for renovascular hypertension.
Forty-six patients who underwent renal artery repair for presumptive renovascular hypertension are presented. Preoperative investigation included a rapid sequence IVP, a high quality angiogram and split function studies, as well as renin assays of renal venous blood in the more recent cases. Atherosclerosis was the causative pathological lesion in 60% of the patients, with fibromuscular dysplasia or miscellaneous causes of stenosis accounting for the remaining 40%.Surgical correction was usually obtained by bypass grafting (57%). Hypertension was cured or significantly improved in 36 patients (78%).Optimal results are dependent upon complete preoperative investigation and surgical repair of all the stenotic areas.
