RENOVASCULAR HYPERTENSION DUE TO TAKAYASUS-ARTERITIS DEMONSTRATED BY TC-99M ETHYLENEDICYSTEINE CAPTOPRIL SCINTIGRAPHY

A 34-year-old woman with severe hypertension underwent Tc-99m ethylene dicycteine (Tc-99m EC) captopril renal scintigraphy. There was bilater al parenchymal retention of the tracer suggesting renal artery stenosi s, Angiography confirmed bilateral renal artery stenosis and also demo nstrated contour irregularities of the abdominal aorta, and stenosis i n mesenteric and subclavian arteries with increased collateral circula tion consistent with Takayasu's arteritis. In light of this case of re nal artery stenosis, it was concluded that Tc-99m EC can be used succe ssfully as a potential renal agent in the diagnosis of renal involveme nt in patients with Takayasu's arteritis.
