【摘要】 目的　探讨肾动态显像对肾血管性高血压 (RVH)的诊断价值。方法　对 5 2例临床上确诊冠心病合并高血压并怀疑RVH的患者进行肾动态显像 ,测定肾功能参数 :2 0min清除率 ,左 右肾血流放射性比值 ,左右肾高峰时间 ,肾小球滤过率 (GFR) ,有效肾血浆流量 (ERPF)。均行肾动脉造影。结果　 5 2例患者中确诊RVH 2 8例 ,肾动态显像灵敏度为 82 14 % ,特异性为 75 0 0 %。RVH组与肾动脉正常组相比 ,肾动态显像的各项参数差异有显著性 (P <0 0 1)。结论　肾动态显像检查有助于RVH的诊断。更多还原

【Abstract】 Objective To evaluate the predictive value of renal scintigraphy in the diagnosis of renovascular hypertension(RVH). Methods Fifty-two cases with coronary heart disease and hypertension were selected. All of them were suspected with RVH,and underwent renal scintigraphy. During the study,clearance rate of 20 minute,time-to-peak,glomerular filtration rate (GFR),effective renal plasma flow (ERPF) were measured. All of the patients took renal arterial angiography. Results Twenty-eight cases were diagnosed with RVH. The diagnostic sensitivity of renal scintigraphy in RVH was 82.14%,and the specificity was 75.00%. There was significant difference in the data of renal scintigraphy between renal arterial stenosis group and normal renal artery group. Conclusion Renal scintigraphy is a noninvasive and effective examination in diagnosis of RVH.更多还原
