早期宫外孕与妊娠黄体的彩色多普勒显像超声诊断

PROPHASE ECTOPIC PREGNANCY AND TRANSVAGINAL COLOR DOPPLER ULTRASONOGRAPHY OF CORPUS LUTEUM GRAVIDITATIS

目的探讨经阴道彩色多普勒显像超声对早期宫外孕及妊娠黄体鉴别诊断的临床价值。方法45例高度怀疑宫外孕患者,经阴道超声观察子宫内膜内血流情况及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来诊断。结果45例患者中,27例为宫内早早孕伴妊娠黄体形成;18例为早期异位妊娠;1例误诊,诊断符合率为97.8%。结论通过经阴道彩超检查子宫内膜及附件区包块的血流分析,能有效鉴别早期宫外孕及妊娠黄体,具有重要临床价值。

Objective To discuss the clinical value of diagnosing prophase ectopic pregnancy and pregnant corpus luteum by transvaginal color doppler imaging. Methods 45 patients with doubtful ectopic pregnancy were performed examine of endometrium hemorrhage and blood stream of the unusual echo area of the adnexa. , the diagnoses were made by blood stream speed full index and resistance index. Results 27 out of 45 patients were early pregnant in uterus combined with formation of pregnant corpus leteum. ,and 18 out of 45 were ectopic pregnants,only 1 patient was misdiagnosed. The rate of right diagnosis reached 97.8% Conclusion Analysing the blood stream of endometriosis and lump of the adnexa by transvaginal color doppler can effectively distinguish prophase ectopic pregnancy and pregnant corpus luteum.
