S. Fanti et al., DIAGNOSIS OF RENOVASCULAR HYPERTENSION WITH CAPTOPRIL RENAL SCINTIGRAPHY IN A PATIENT WITH A SOLITARY KIDNEY, The Journal of nuclear medicine, 34(7), 1993, pp. 1166-1168
A patient with a solitary kidney due to renal agenesis and contralater
al kidney perfusion impairment due to renal artery stenosis was succes
sfully treated with percutaneous transluminal renal angioplasty. Prein
tervention diagnostic work-up included captopril renal scintigraphy, w
hich was suggestive of high probability of renovascular hypertension.
Scintigraphic assessment 2 mo after angioplasty failed to show any abn
ormality after captopril administration, a finding in line with blood
pressure beneficial response to renal artery revascularization. A 12-m
o follow-up confirmed cure of hypertension.
