【摘要】 本文通过彩色多普勒（ＣＤＦＩ）对３０例正常对照组（６０条精索静脉）和４６例精索静脉曲张组（５０条曲张精索静脉）的血流动力学变化进行对比分析。结果显示：（１）精索静脉曲张组血管内径明显大于对照组，有显著性差异（Ｐ＜０．００１）。若以血管内径≥０．１８ｃｍ作为诊断标准，则敏感性１００％，特异性９６．６７％，准确性９８．１８％；（２）精索静脉曲张组平均血流速度低于对照组，有显著性差异（Ｐ＜０．０５）；（３）通过返流与体位、呼吸的关系，提出了ＣＤＦＩ诊断精索静脉曲张程度的分级标准。进一步论证了ＣＤＦＩ分级与临床分级所得的一致性结果有非常显著性意义（Ｐ＜０．００１）。因此作者认为：ＣＤＦＩ对精索精脉曲张的诊断及扩张程度的判断具有重要价值，并为临床诊断提供了新途径。更多还原

【Abstract】 The hemodynamics was detected by CDFI in 46 varicocele patients and 30 normal controls.The results showed that:(1)There was a great increase of the vascular inside diameter in the varicocele patient vs. the normal control with significant difference(P<0.001).Diameter above or equel to 0.18cm is recognized as the diagnostic criterion. The sensitivity,specificity and accuracy were 100%, 96.67%and 98.18% respectively.(2)Significant decrease of the average flow velocity in the varicocele patients vs. the normal control with significant difference(P<0.05).(3)Changing posture or practising respiration as instructed to the patient in addition to CDFI findings may improve clinical varicocelc diagnosis.更多还原
