Combined transvaginal and abdominal ultrasound in the diagnosis of early ectopic pregnancy

Abstract

Objective To observe the accuracy of abdominal ultrasound combined with transvaginal ultrasound in the early diagnosis of ectopic pregnancy, thus to provide reference for clinical diagnosis of ectopic pregnancy. Methods The clinical data of 68 patients, who pathologically confirmed or conservative treatment with clinical diagnosis of ectopic pregnancy, were retrospectively analyzed.All patients were treated with abdominal ultrasound, vaginal ultrasound examination.The accuracy and missed ectopic pregnancy rate of transvaginal ultrasound and abdominal B ultrasound and joint inspection were observed.And the presence or absence of abnormal ovarian uterus were recorded. Results By comparison with pathological diagnosis, joint diagnosis of 32 cases of ectopic pregnancy, the diagnosis rate was 94.1%, missed 2cases, accounted for 5.9%; Transvaginal ultrasound diagnosis were 26 cases, accounted for 76.5%, missed by 8 cases, accounted for 23.5%; Abdominal ultrasound diagnosis were 24 cases, accounted for 70.6%, missed 10 cases, accounted for 29.4%.Joint inspection diagnosis rate was significantly higher than abdominal or vaginal ultrasound(χ2=16.75, 14.38, all P 0.05).Transvaginal ultrasound detected primitive heart tube pulse, mass, blood flow and gestational sac-like structures within the mass were significantly higher than the probability of abdominal ultrasound(χ2=26.71, 7.18, 10.25, 50.28, 25.69, 6.39, all P<0.05). Conclusion United abdominal ultrasound and transvaginal ultrasound can significantly improve the early detection rate of ectopic pregnancy, which can provide reference for clinical diagnosis and treatment.
