title: Radionuclide evaluation of renal artery dilatation.
abstract: Radionuclide studies were sued in three patients to evaluate renal perfusion and function within 24 hours following transluminal dilatation. In one patient, technetium-99 m pertechnetate showed good renal perfusion one and 12 hours after a post-dilatation arteriogram had shown a renal artery intimal defect. Improved clearance of iodine-131 ortho-iodohippurate from the blood demonstrated an increase in renal function 18 hours following dilatation of a stenosis at a renal allograft anastomosis in the second patient, while technetium-99 m-labeled DTPA showed an improved total glomerular filtration rate 24-hours after dilatation of a saphenous vein bypass graft in the third patient. It was concluded that renal radionuclide studies are of benefit in evaluating patients in the immediate post-dilatation period.
