彩色多普勒对亚临床型精索静脉曲张不育患者的诊断价值

目的:探讨彩色多普勒(CDFI)对亚临床型精索静脉曲张(SVC)不育患者的诊断价值。方法:采用CDFI检测56例精液异常不育患者的精索静脉,观察蔓状静脉血管内径及血液返流时间,并行X线选择性精索内静脉造影对照分析。结果:平静状态下蔓状静脉内径为(2.24±0.16)mm;Valsalva运动时内径为(2.67±0.26)mm;返流时间为(1 487±203.66)m s,CDFI检测SVC的准确性为92.8%。结论:在男性不育的病因筛选中,CDFI检测对SVC的诊断比临床型精索静脉曲张更有意义。

Value of Color Doppler Flow Imaging in the Diagnosis of Subclinical Varicocele

OBJECTIVE: To identify the value of color Doppler flow imaging (CDFI) in the diagnosis of sterility caused by subclinical varicocele (SVC). METHODS: The spermatic veins of 56 sterile patients with seminal abnormality were examined with CDFI and the internal diameters and the time of blood reflux of pampiniform plexus of the veins were observed. In addition, selective X-ray examination of internal spermatic veins was performed for contrast analysis. RESULTS: The diameter of the pampiniform plexus was (2.24 +/- 0.16) mm under the static condition and (2.67 +/- 0. 26) mm during the Valsalva test. The time of blood reflux was (1 487 +/- 203.66) ms. The accuracy of CDFI for diagnosing SVC was 92.8%. CONCLUSION: CDFI has been proved of more value in the diagnosis of SVC than that of clinical varicocele in the etiological screening of male sterility.
