Renovascular hypertension identified by captopril-induced changes in the renogram.
Radioisotope renography was performed in 21 patients with hypertension and unilateral renal artery stenosis with and without premedication with 25 mg of captopril, and the results were compared with the effect of percutaneous transluminal angioplasty on the blood pressure, assessed 6 weeks after angioplasty. Angioplasty caused a considerable decrease in blood pressure in 15 of the 21 patients. ...
متن کاملComparison of aspirin renogram and captopril renogram in the diagnosis of renovascular hypertension
Renal artery stenosis (RAS) is the most common cause of secondary hypertension. Preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection RAS. In this study 20 patients with known or suspected RAS underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mTc-DTPA. Renal an...

متن کاملRenal scintigraphic captopril test in the diagnosis of renovascular hypertension.
Angiotensin converting enzyme (ACE) inhibitor-induced renal failure has been reported in bilateral renal artery stenosis and in stenosis in solitary kidneys, but not in unilateral renal artery stenosis. In these patients, however, a functional impairment of the kidney ipsilateral to the stenosis can often be detected after ACE inhibition by scintigraphic techniques employing glomerular radionuc...
متن کاملCaptopril stimulation of differential renins in renovascular hypertension.
Twenty-six patients being evaluated for renovascular hypertension were studied to assess the diagnostic value of enhancing the differential between renal venous renins (PRA) by a single 25 mg oral dose of converting enzyme inhibitor (CEI, captopril). Antihypertensive medications were not discontinued prior to the study, and renal venous effluent was sampled before and 30 minutes after CEI. Eigh...
