Application of ultrasonography in diagnosis and treatment of intrauterine pregnancy complicated with cornual pregnancy after in-vitro fertilization embryo transfer

Abstract

The clinical data of 39 cases of intrauterine pregnancy complicated with cornual pregnancy after in-vitro fertilization embryo transfer(IVF-ET) were analyzed retrospectively.All the patients were diagnosed by transvaginal ultrasound in early pregnancy, and the position of the gestational sac and its external process were determined by transvaginal ultrasound. According to the location and size of the gestational sac, the patients were divided into two groups: in group A (n=29) the gestational sac was located close to the interstitial tube and the gestational sac was larger, prominent out of the corners of the uterus; in group B (n=10) the gestational sac was located towards the uterine cavity, gestational sac was smaller and the embryo was not active. The laparoscopic angle wedge resection for group A and ultrasound-guided embryo reduction for group B were performed respectively. After treatment, 38 cases were stable to term delivery with intrauterine pregnancy; abortion occurred in 1 case of group A 2 weeks after operation. The early diagnosis and treatment is very important for intrauterine pregnancy complicated with cornual pregnancy. Ultrasonography provides an accurate preoperative assessment and intraoperative real-time monitoring during embryo reduction, which provides an alternative approach for the treatment of intrauterine pregnancy combined with cornual pregnancy.
