Abstract

Renovascula hypertension is the most important and common cause of secondary hypertension. We studied 10 patients with arterial hypertension and different degrees of renal artery stenosis to assess the usefulness of dynamic radionuclide renography in evaluating renal perfusion and funcion, and to compare funcional radionuclide results to the morphological findings of renal angiography. Computer-assisted dynamic renal with {sup 00m}Tc diethylenetriaminepentaacetic acid (DTPA) and {sup 131}I orthoiodohippurate (OIH), and renal artheriography were also employed in all patients. In all patients, radionuclide results matched angiography findings in quality. In particular, 3 patients with hemodynamical insignificant renal artery stenosis exhibited normal perfusion and function at dynamic radionuclide renography. Seven patients had significant renal artery stenosis and associated functional changes at dynamic radionuclide renography. Quantitative comparison of all patients showed a significant correlation (r=0.866, p<0.001) between the degree of renal artery stenosis, quantified as the percentage of narrowing as compared to adjacent/contralateral normal vessel diameter, and the results of split renal function, as assessed during OIH studies and expressed per kidney as a percentage of the net total counts of both kidneys. In conclusion, our results demonstrated dynamic radionuclide renography to be a valuable secondary to renal artery stenosis in hypertensive patients, providing complementary  More>>
