B-flow超声显像技术诊断精索静脉曲张

Ultrasound B-flow imaging in diagnosis of varicocele

目的探讨B-flow超声显像技术对精索静脉曲张的诊断价值。方法将30例彩色多普勒超声已经诊断精索静脉曲张的患者按临床症状分为临床型和亚临床型,分别进行B-flow显像,观察反流情况,测量部分患者的反流时间与反流速度,并进行统计学分析。结果临床型和亚临床型精索静脉曲张两组之间静脉内径有明显差异(P<0.01)。CDFI和B-flow对于临床型组反流阳性检出率之间存在明显差异(P<0.05),而两者对于亚临床型组阳性检出率之间存在明显差异(P<0.01)两组患者在反流时间与反流速度之间均存在显著差异(P<0.01)(P<0.05)结论B-flow显像技术能更好地诊断精索静脉曲张,特别能提高亚临床精索静脉曲张反流阳性检出率,对于早期临床症状不明显的亚临床型精索静脉曲张诊断有重要意义。

Objective To investigate the value of B-flow imaging in detecting the varicocele. Methods Totally,30 patients with varicocele diagnosed by CDFI were divided into clinical and subclinical groups according to their symptoms. Then they were exmined by B-flow imagining to observe the reflux, and reflux time and velocity were measured by Doppler technique. Data were recorded and analyzed statistically. Results There were significant differences in blood vessel diameter, reflux time and velocity between the clinical and the subclinical groups （P〈0.0l）.There were still significant differences in blood vessel reflux positive rate between CDFI and B-flow in clinical group （P〈 0.05）,and the differences were more significant in subclinical group （P〈0.01）. Conclusion B-flow imaging is better than CDFI in the detection of varicocele and it improves the blood vessel reflux positive rate especilly in subclinical group. B-flow imaging is valuable in the diagnosis of varicocele patients without clinical symptoms.
