摘要 目的探讨经阴道彩色多普勒超声检查对宫颈癌盆腔淋巴结转移的诊断价值。方法选取2015年1月至2017年12月本院收治的行经阴道彩色多普勒超声检查的70例宫颈癌患者为研究对象,将其血流信号和血流动力学参数与手术病理结果进行对照,分析经阴道彩色多普勒超声检查对宫颈癌盆腔淋巴结转移的诊断价值。结果经阴道彩色多普勒超声诊断盆腔淋巴结转移患者41例,其中,宫颈癌分期Ⅱ期32例、Ⅲ期7例、Ⅳ期2例。以病理检查结果作为金标准,经阴道彩色多普勒超声检出盆腔淋巴结转移的准确率为91.11%(41/45),敏感度为97.37%(37/38),特异度为87.50%(28/32)。在有盆腔淋巴结转移患者中,血流丰富患者占29.27%,高回声患者占21.95%;而在无淋巴结转移患者中,血流丰富患者仅占3.45%,无高回声患者,两组比较差异均具有显著性(P_均<0.05);有盆腔淋巴结转移患者的阻力指数显著低于无盆腔淋巴结转移患者(P <0.05)。结论经阴道彩色多普勒超声可以清晰显示宫颈癌患者盆腔淋巴结转移的范围和侵犯程度,具有重要的诊断价值。 Objective To evaluate the diagnostic value of transvaginal color Doppler ultrasonography in pelvic lymph node metastasis of cervical cancer. Method From January 2015 to December 2017, 70 patients with cervical cancer who underwent transvaginal color Doppler ultrasonography were enrolled in this study. The blood ?ow signals and hemodynamic parameters were compared with the surgical pathological results, in order to analyze the diagnostic value of transvaginal color Doppler ultrasonography for pelvic lymph node metastasis of cervical cancer. Result Transvaginal color Doppler ultrasound was used to diagnose 41 patients with pelvic lymph node metastasis, including 32 cases with stage Ⅱ, 7 cases with stage Ⅲ, and 2 cases with stage Ⅳ. Taking the results of pathological examination as the gold standard, the accuracy of ultrasonography in the diagnosis of pelvic lymph node metastasis was 91.11%(41/45), the sensitivity was 97.37%(37/38), and the specificity was 87.50%(28/32). Among patients with pelvic lymph node metastasis, 29.27% had abundant blood ?ow and 21.95% had hyperechoic blood ?ow;among patients without lymph node metastasis, only 3.45% had abundant blood ?ow and no hyperechoic patients. There were signi?cant differences between the two groups(Pall< 0.05). The resistance index of patients with pelvic lymph node metastasis was signi?cantly lower than that of patients without pelvic lymph node metastasi(P < 0.05). Conclusion Transvaginal color Doppler ultrasonography can clearly show the extent and extent of pelvic lymph node metastasis in patients with cervical cancer, and has important diagnostic value.
