【摘要】 通过彩色多普勒对１２５例不育症男性患者，共２５０条精索静脉的血流动力学变化进行研究。结果显示彩色多普勒诊断精索静脉曲张７１例，其中４６例与临床诊断一致，２５例诊断为亚临床型精索静脉曲张，占不育症患者的２０％。提出将精索静脉直径≥０．１８ｃｍ，返流时相大于８００ｍｓ可作为诊断亚临床型精索静脉曲张的标准。证实了彩色多普勒是一种简单、有效、方便和非侵害的检查方法更多还原

【Abstract】 The hemodynamics of spermatic vein was studied by CDFI in 125 infertile men. The results showed that by CDFI there were 71 cases of varicocele diagnosed. Among them, the diagnosis of 46 cases was coincident with clinical ones and 25 cases were diagnosed as subclinical varicocele. It is suggested that the diagnostic criteria of subclinical varicocele are when the diameter of spermatic vein is ≥ 0.18 cm and the time of regurgitation>800 ms. CDFI is proved to be an easy, effective, convenient and noninvasive method for the examination of subclinical varicocele.更多还原
