经腹与经阴道彩超检查对异位妊娠子宫附件血循环的对比研究

Uterus and Appendages Blood Circulation in Ectopic Pregnancy with Transabdominal and Transvaginal Color Dopplor Sonography-A Comparative Study

目的:探讨经腹部彩超(TACD)与经阴道彩超(TVCD)对早期异位妊娠子宫附件血循环检测的差异。方法:对收治的97例异位妊娠随机分为TACD组(47例)和TVCD组(50例),分别采用TACD及TVCD检测患者的子宫动脉、肌层螺旋动脉及滋养动脉的阻力指数(RI值),并对所得数据及检出率进行对比分析。结果:TVCD组与TACD组检测子宫动脉RI值>0.80的分别占95.74%和94%,两组比较差异无统计学意义(P>0.05);滋养动脉的检出率分别为90%、61.7%,两组比较差异有统计学意义(P<0.01);螺旋动脉的检出率分别为44%、23.4%,两组比较差异有统计学意义(P<0.05),但两种方法所测滋养动脉的平均RI值差异无统计学意义(P>0.05)。结论:TVCD检测妊娠子宫附件血循环的状况对早期诊断异位妊娠较TACD更具优势。

Objective：To study the differences of transabdominal color dopplor sonography （TACD） and transvaginal color dopplor sonography （TVCD） in detection of uterus and appendages blood circulation in ectopic pregnancy. Methods：The RI of uterine artery,uterine spiral artery and nutrient artery of 47 patients and 50 patients with ectopic pregnancy were measured respectively by TACD and TVCD, and the data and detection rate were analyzed compared. Results： High resistance blood flow was shown in the two groups＇uterine arteries, and the percentage of cases with the RI of uterine artery beyond 0.80 were 95.74% and 94% respectively （P 〉 0.05） in the two groups, the detection rate of nutrient artery in TVCD group （ 90% ） was higher than that of TACD group（ 61.7% 0）, showing statistical significance （P 〈0. 01 ） ,and the detection rate of spiral artery in TVCD group （44%） was higher than that of TACD group （23.4%）, showing statistical difference （P 〈 0.05 ）, and there was no significant difference in RI values of nutrient artery between the two groups（P 〉 0.05）. Conclusion ：TVCD seems to be superior to TACD in early diagnosis of ectopic pregnancy by detecting uterus and appendages blood circulation.
