彩色多普勒超声检测精索静脉曲张不育患者睾丸包膜动脉的研究

目的:探讨应用彩色多普勒超声(CDFI)检测精索静脉曲张(VC)不育患者睾丸包膜动脉的临床价值。方法:符合左侧VC入选标准的39例不育患者及36例健康志愿者入组。受检者均用CDFI测量左侧睾丸包膜动脉(LCA)的收缩期峰值流速(PSV)、舒张末期峰值流速(EDV)、平均流速(Vm)、阻力指数(RI)、搏动指数(PI)。结果:两组的LCA-EDV及LCA-Vm无显著性差异(P>0.05);与正常对照组比较,病例组LCA-PSV、LCA-RI及LCA-PI均明显升高(P<0.05)。结论:用CDFI获得的LCA-PSV、LCA-RI及LCA-PI可作为临床早期诊断男性不育症的较好参考指标。

Objective：To investigate the value of Color Doppler Flow Imaging （CDFI） in evaluating testicular capsular artery of left varicocele（LVC） infertile patients.Methods：A total of 39 LVC infertile patients and 36 normal subjects were involved in this study.The peak systolic velocity（PSV）,end diastolic velocity（EDV）,mean velocity（Vm）,resistance index（RI）and pulsatility index（PI） of left testicular capsular artery（LCA） were measured using CDFI.The parameters of LVC group and control group were compared.Results：There was no significant difference between the two groups with respect to LCA-EDV and LCA-Vm （P〉0.05）.But LCA-PSV,LCA-RI and LCA-PI of LVC group were different significantly compared with the control group （P〈0.05）.Conclusion：The LCA-PSV,LCA-RI and LCA-PI of testicular capsular artery measured by CDFI may be sensitive reference indexes for diagnosing the infertile patients.
