Differential renal function during angiotensin converting enzyme inhibition in renovascular hypertension.

Renal Scintigraphy Following Angiotensin Converting Enzyme Inhibition in the Diagnosis of Renovascular Hypertension (Captopril Scintigraphy)

Renovascular hypertension (R VH) may be due to unilateral or bilateral stenosis of the main renal artery (RAS), branch arterial stenosis, whole kidney or focal renal infarction, aneurysms, or arteriovenous malformations. Other entities such as hydronephrosis, renal cysts, or neoplasms may produce high renal vein renin hypertension, but they do not belong to the classic group of causes of renova...

Effects of converting enzyme inhibition on split renal function in renovascular hypertension.

The effects of captopril on effective renal plasma flow and glomerular filtration rate were studied using a noninvasive radioisotopic method on individual kidneys in eight patients with renovascular hypertension and 12 patients with essential hypertension with various renin levels. Four patients with renovascular hypertension had unilateral while three had bilateral renal artery stenosis. The e...

Angiotensin Converting Enzyme in Sarcoidosis

Angiotensin converting enzyme inhibition improves diagnostic procedures for renovascular hypertension in dogs.

In renovascular hypertension adaptive mechanisms in the poststenotic kidney are a probable cause of the 20 to 25% false-negative findings during rapid sequence urography or [123I]o-iodohippurate renography. We blocked the renin-angiotensin system in an effort to increase the yield of these diagnostic procedures. Chronically instrumented, salt-depleted conscious dogs were used in which a light (...
