Abstract:

Objective: To explore the value of trans-vaginal ultrasonography in the diagnosis of early ectopic pregnancy. Methods:
120 patients with suspected ectopic pregnancy and having undergone operations in Yijishan Hospital of Wannan Medical College from
January to December 2017 were analyzed retrospectively, and the coincidence rate of ectopic pregnancy diagnosed by trans-vaginal
ultrasound was judged by the pathological examination as gold standard after operation. Results: Among the 120 cases of ectopic
pregnancy were diagnosed by trans-vaginal ultrasound, 88 cases were diagnosed as extrauterine pregnancy（55 cases of ampulla, 32
cases of isthmus, and 1 case of interstitial part）, 12 cases as uterine horn pregnancy and 20 cases as cesarean scar pregnancy. Compared
with surgical pathology, the coincidence rate of trans- vaginal ultrasound examination was 95.8% . Conclusion: Trans-vaginal
ultrasound has a good clinical value in the diagnosis of ectopic pregnancy.
