摘要
目的:探讨经阴道彩色多普勒超声显像对宫旁早期异位妊娠及妊娠黄体鉴别诊断的临床价值。方法:经彩色多普勒血流显像对296例宫旁妊娠与234例妊娠黄体进行对比分析,观察附件区异常回声区的血流分布情况,并根据血流速度、充盈度及阻力指数等指标鉴别诊断。结果:宫外孕团块周边及内部血流呈条状、点状的占73.0%,呈无明显血流的占10.1%,PSV:(13.3±9.6)cm/s,RI:(0.43±0.08);妊娠黄体周边血流呈环状或半环状的占96.8%,PSV:(33.2±8.2)cm/s,RI:0.41±0.09。结论:经阴道彩超检查子宫附件区包块的血流分析,能有效鉴别早期异位妊娠及妊娠黄体,具有重要临床价值。
Objective： To explore the clinical value of transvaginal color Doppler imaging in differentiation of parauterine prophase ectopic pregnancy and pregnant corpus luteum. Methods： 296 patients with parauterine prophase ectopic pregnancy and 234 patients with pregnat corpus luteum were compared and analysed by color Doppler flow imaging, the distribution of blood flow of unusual echo area of the adnexa was observed, then diagnosis was made by blood flow rate, fullness degree and resistance index. Results： 73.0% of echo of blood flow intra- and peri -ectopic pregnancy was punctate and stripy, while 10. 1% had no obvious blood flow. PSV： （13.3±9.6） cm/s, RI： （0.43± 0. 08 ） ; 96. 8% of the cases showed the blood flow as a ring or a half ring - like in corpus luteum. PSV ： （ 33.2 ± 8. 2） cm/s, RI ： （0.41 ± 0.09） . Conclusion： Examining the blood stream of lump of adnexa by transvaginal color Doppler uhrasonography may distinguish prophase ectopic pregnancy and pregnant corpus luteum effectively.
