Percutaneous transluminal renal angioplasty (PTRA) was performed in a patient with bilateral renal artery stenoses diagnosed noninvasively by captopril renal scintigraphy and confirmed by renal arteriography. The captopril renal scintigraphy parameters returned to normal in correlation with improved blood pressure response fifteen days after PTRA. Five months later hypertension reappeared and the repeated captopril renal scintigraphy suggested left renal artery stenosis. PTRA was repeated and a stent was implanted with reversal of blood pressure, and captopril renal scintigraphy findings returned to normal levels. Six months after second PTRA, the blood pressure increased to hypertensive levels, and captopril renal scintigraphy indicated left renal artery stenosis. The renal arteriography, however, revealed a new stenosis at the left renal artery ostium. The PTRA with a second stent implantation was performed successfully. The captopril renal scintigraphic parameters and the blood pressure were again normalized after the last intervention and remained normal for thirteen months of follow-up.
一名双侧肾动脉狭窄患者接受了经皮腔内肾血管成形术（PTRA）。该患者通过卡托普利肾闪烁显像无创诊断出双侧肾动脉狭窄，并经肾动脉造影证实。PTRA术后15天，卡托普利肾闪烁显像参数恢复正常，同时血压反应改善。五个月后高血压复发，重复的卡托普利肾闪烁显像提示左肾动脉狭窄。再次进行PTRA并植入支架，血压恢复正常，卡托普利肾闪烁显像结果也恢复到正常水平。第二次PTRA术后六个月，血压升至高血压水平，卡托普利肾闪烁显像显示左肾动脉狭窄。然而，肾动脉造影显示左肾动脉开口处出现新的狭窄。成功进行了再次PTRA并植入第二个支架。最后一次干预后，卡托普利肾闪烁显像参数和血压再次恢复正常，并在后续的13个月随访中保持正常。
