Studies of Patients with Renal Hypertension Undergoing Vascular Surgery

IT is now well established that renal ischemia, unilateral or bilateral, brought about by any pathologic process, may cause hypertension in man,1 , 2 as it does in animals.3 As in animals, if the renal ischemia is unilateral, and the contralateral kidney is normal, or at least not ischemic, excision of the ischemic kidney cures the hypertension.4 5 6 No fall in the blood pressure was observed when the more diseased kidney was removed from a patient with bilateral nephrosclerosis.7 Since the ischemia in the laboratory animal is due to constriction of the main renal artery by a metal clamp and not to organic, . . .
