Role of the captopril test in renovascular hypertension: a case report.
This article reports the case of a rapidly severe stenosis of the right renal artery, causing uncontrolled hypertension. After failure of a percutaneous transluminal renal angioplasty, which provoked the thrombosis of the vessel, a surgical revascularization was performed after +/- eighteen hours of renal ischemia. Blood pressure, blood urea nitrogen and serum creatinine returned to normal values. A dramatic improvement of the right renal function was attested at the hippuran scintigraphy after a dose test of captopril. The results of renographic studies obtained in this clinical case underline the role of the captopril radionuclide test in detection and follow-up after treatment of renovascular hypertension.
