Hypertension and unilateral vascular occlusion Diagnosis and surgical intervention

Four hypertensive patients with unilateral atheromatous renal arterial occlusion have been studied. Each showed elevation of renal venous activity on the side of the vascular occlusion relative to the opposite side. Three of the patients underwent nephrectomy with amelioration of their hypertension. It is concluded that surgical treatment is valid therapy in patients with atheromatous unilateral renal vascular occlusion and ipsilateral elevation of renal venous renin activity.
