目的经阴道二维超声及CDFI对异位妊娠进行诊断分析,提高定位的准确性。方法我院2012年1月至2013年1月经阴道超声提示异位妊娠、血HCG阳性并经手术证实的患者133例,对其声像图改变、病史及血HCG值进行回顾性分析。结果 133例患者中,输卵管妊娠125例(占94%),诊断符合率98.4%)其中2例间质部妊娠诊断为宫角妊娠。腹腔妊娠2例(占1.5%),诊断符合率100%。子宫颈妊娠2例(1.5%),诊断符合率100%,剖宫产切口处妊娠3例(占2.3%),诊断符合率100%,卵巢妊娠1例(0.8%)误诊1例。未破裂性16例,CDFI示周边可见丰富血流或星点状血流,为高速低阻型血流。流产破裂型并盆腔积液109例,周边及内部未见血流信号或血流信号不丰富。结论经阴道超声诊断异位妊娠具有较高的准确性,可为临床提供可靠诊断依据。
Objective Transvaginal two-dimensional ultrasound and CDFI diagnosis of ectopic pregnancy to improve the accuracy of positioning. Methods Transvaginal ultrasound in our hospital from January 2012 to January 2013 prompted ectopic pregnancy, blood HCG-positive and confirmed by surgery in 133 patients, the changes of its sonographic findings, history and blood HCG values were retrospectively analyzed. Results Of the 133 patients, 125 cases of tubal pregnancy (94%) were diagnosed as having a coincidence rate of 98.4%), and 2 of them were diagnosed as uterine horn pregnancy. 2 cases of intraperitoneal pregnancy (1.5%), the diagnostic coincidence rate of 100%. Cervical pregnancy in 2 cases (1.5%), the diagnostic coincidence rate of 100%, cesarean section at the pregnancy in 3 cases (2.3%), the diagnostic coincidence rate of 100%, ovarian pregnancy in 1 case (0.8%) misdiagnosis in 1 case. Non-rupture in 16 cases, CDFI showed peripheral rich blood flow or star-like blood flow, high-speed low resistance blood flow. Abortion rupture and pelvic fluid in 109 cases, peripheral and internal no blood flow signal or blood flow signal is not rich. Conclusion Transvaginal ultrasound diagnosis of ectopic pregnancy with high accuracy, clinical diagnosis can provide a reliable basis.
