为了提高肾动脉狭窄的无创性检测,我们在犬两肾一夹高血压模型上,观察了血管紧张素转换酶抑制对计算机辅助99mTC-二乙三胺五乙酸(DTPA)肾血流研究的影响,并与抑制转换酶前后狭窄侧和对侧肾脏菊粉和对氨基马酸的清除情况进行了比较。使用转换酶抑制剂卡托普利(1.5 mg/kg静脉滴注1.5 mg/min)进行的99mTC-DTPA肾血流研究显示,与单独使用99mTC-DTPA研究相比,在检测单侧肾动脉狭窄方面具有更高的敏感性。卡托普利引起的显著改变在15分钟的99mTC-DTPA肾血流研究中最为明显,所有9条曲线都显示放射性核素的摄取和排泄严重钝化。在没有转换酶抑制的恢复研究中,这些变化被逆转,当硝普钠将血压降低到与转换酶抑制时观察到的水平相似时,这些变化不会出现。99mTC-DTPA研究表明,转换酶抑制期间的变化与狭窄肾的肾小球滤过率降低有关。卡托普利显著降低狭窄侧肾的肾小球滤过率(16.0+/-3.1vs11.0+/-2.5 mg/min,p<0.03),但对侧肾(32.4+/-2.6vs28.4+/-2.8 mg/min)无明显影响。
In an effort to improve on the noninvasive detection of renal artery stenosis, we investigated the effect of angiotensin converting enzyme inhibition on computer-assisted 99mTc-diethylenetriaminepentaacetic acid (DTPA) renal flow studies in a canine model of two-kidney, one clip hypertension and compared these findings with clearances of inulin and p-aminohippuric acid in the stenotic and contralateral kidney before and after converting enzyme inhibition. The 99mTc-DTPA renal flow study with the converting enzyme inhibitor captopril (1.5 mg/kg bolus with 1.5 mg/min infusion) showed an increased sensitivity in the detection of unilateral renal artery stenosis over the use of the 99mTc-DTPA study alone. Captopril induced striking alterations that were most evident in the 15-minute 99mTc-DTPA renal flow study, in which all nine curves exhibited severely blunted uptake and excretion of the radionuclide. These changes were reversed during a recovery study without converting enzyme inhibition and were not seen when blood pressure was lowered with nitroprusside to a level similar to that observed during converting enzyme inhibition. The changes shown by the 99mTc-DTPA study during converting enzyme inhibition correlated with a decrease in the glomerular filtration rate of the stenotic kidney. Captopril infusion significantly decreased the glomerular filtration rate of the stenotic kidney (16.0 +/- 3.1 vs 11.0 +/- 2.5 mg/min, p less than 0.03) but not of the contralateral kidney (32.4 +/- 2.6 vs 28.4 +/- 2.8 mg/min).(ABSTRACT TRUNCATED AT 250 WORDS)
