经阴道彩色多普勒超声诊断局部中晚期宫颈癌

Transvaginal color Doppler ultrasound in diagnosis of locally advanced cervical carcinoma

目的探讨经阴道彩色多普勒超声诊断局部中晚期宫颈癌的价值及宫颈癌的声像图特征。方法对106例经手术与病理证实的宫颈癌患者的二维声像图及CDFI表现进行了回顾性分析。结果局部中晚期宫颈癌经阴道彩色多普勒声像图表现具有特征性:宫颈增大、宫颈部低回声肿块、正常宫颈管结构消失、宫颈外浸润性肿块等图像改变;宫颈肿块内异常丰富彩色血流,呈“火球样”改变;而早期宫颈癌宫颈无明显增大及特异性改变;宫颈部肿块内血流动脉阻力指数平均0.41。结论经阴道彩色多普勒超声对局部中晚期宫颈癌病变范围、是否周围侵犯、肿块的血供情况等具有较大诊断价值,可作为局部中晚期宫颈癌治疗前常规的辅助检查方法。

Objective To investigate the clinical value and sonographic features of locally advanced cervical carcinoma using transvaginal color Doppler ultrasound（TVCDU）. Methods A retrospctive analysis was carried on 2 - D sonograms. And color Doppler flow imaging（CDFI） in 106 cases, confirmed by pathology and surgery. Results In locally advanced cervical carcinoma, the characteristerics on TVCDU were cervical enlargment, cervical masses accompanying with uteral effusion and extracervical infiltrative masses. The rich cervical blood flow signals demonstrated as called ＂fireball＂ sign. In early cervical carcinoma,the cervix showed no apparent cervical enlargment. The blood flow signals were increased. The average RI was 0.41. Conclusions TVCDU which is very valuable in judging the infiltration extent and in differential diagnosis preoperatively can be used as a routine examination method before locally advanced cervical carcinoma treatment.
