Renovascular Hypertension: Pathophysiology, Diagnosis, and Treatment
Renovascular hypertension can result from renal artery lesions involving the main renal artery, or its branches. It is generally felt that the elevation of blood pressure results from excessive systemic vasoconstriction secondary to enhanced renin secretion by one or part of one kidney. Renin secretion is enhanced because of constriction of the renal artery and resultant intrarenal ischemia. Cl...
متن کاملClinical Conference Pathophysiology of Renovascular Hypertension Principal Discussant
Renovascular hypertension has its experimental counterpart in the two-kidney, one clip model (Goldblatt hypertension). From the study of this model, a general pathophysiological scheme has evolved suggesting that temporal stages in the development and maintenance of hypertension are regulated by complicated hormonal and neural interrelations. The central roles played by the renin-angiotensin sy...
متن کاملNew Insights Into Pathophysiology, Diagnosis, and Treatment of Renovascular Hypertension.
Renovascular disease includes renal artery stenosis, renovascular hypertension, and azotemic renovascular disease (ischemic nephropathy). Renovascular hypertension is defined as an elevated blood pressure caused by renal hypoperfusion, usually resulting from anatomic stenosis of the renal artery and activation of the renin-angiotensin system. It accounts for 1% to 2 % of all cases of hypertensi...
متن کاملRenovascular Hypertension
The effect of hypertension and of therapy by converting enzyme inhibitor (S 9490-3, perindopril) on the function and structure of large arteries has been studied in two-kidney, one-clip Gddblatt hypertensive rats. After one month without treatment, clipped hypertensive rats (n = 24) and sham-operated rats (n = 24) were randomly allocated to treatment by S 9490,1 mg/kg once a day (n = 24) or to ...
متن کاملRenovascular hypertension.
If only 1 per cent of the 23 million hypertensive patients in the United States had renovascular hypertension, many patients would be denied the chance for cure. Strong clinical suspicion plus arteriography are the mainstays of diagnosis. Positive renal vein renin studies provide the best preoperative evidence for cure by operation, but many patients with negative studies benefit from operation...
