Baseline and single-dose captopril scintigraphy with 1 mCi of 99mTc-diethylenetriamine-pentaacetic acid (or 99mTc-glucoheptonate) was performed in 5 neonates with renovascular hypertension. Unilateral renal artery thrombosis and/or renal infarction was associated with severe impairment or lack of function on both studies (3 patients). Renal ischemia due to aortic thrombus manifested itself as lack of function only following captopril (2 patients). This approach predicted renal failure as a side effect of captopril therapy in 2 patients, 1 with unilateral (contralateral kidney infarcted) and the other with bilateral renal ischemia from aortic thrombus. Single-dose captopril scintigraphy may be a useful tool to predict tolerance to captopril therapy.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph. Gamma Camera Imaging,Radioisotope Scanning,Scanning, Radioisotope,Scintigraphy,Scintiphotography,Imaging, Gamma Camera,Imaging, Radionuclide
D002216 Captopril A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.

D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions. Cannulation,Cannulations,Catheterizations

D014465 Ultrasonics A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues. Ultrasonic
