The blood pressure response to operative treatment in 502 patients with
renal artery stenosis and coexisting hypertension was as follows: 51%
cured, 15% improved, and 34% failure. The operative mortality was 5.9%.
Patients with unilateral fibromuscular disease had a favorable blood
pressure response (79.8%) more frequently than the patients with unilateral
atherosclerosis (63.4%). In patients with bilateral stenosis, a favorable
result occurred in 56%. The anatomic failure rate due to thrombosis of
arterial reconstructions, as well as the operative mortality, varied
considerably between institutions. If preoperative diagnostic studies
demonstrated significant functional disparity between kidneys, and if the
operation was anatomically successful, then approximately 80% of these
patients were benefited by surgical intervention.
