Abstract To explore the application of the transvaginal color Doppler ultrasonography for diagnosing the heterotopic pregnancy (HP) of patients after in vitro fertilizationembryo transfer (IVF-ET), and to study the effect of the laparoscopic surgery for treating HP of the patients. Methods: The clinical data of 80 patients with HP after IVF-ET from March 2020 to December 2022 were analyzed retrospectively. The accuracy rate diagnosed by ultrasound, the clinical manifestations, the ultrasonogram characteristics, the situations of the laparoscopic surgery and the pregnancy outcomes of the patients were analyzed. Results: The HP of 71 patients was diagnosed by transvaginal color Doppler ultrasound, with the diagnostic accuracy rate of 88.8%. There were 4 (5.0%) patients with the delayed diagnosis of HP and 5 (6.3%) patients with the misdiagnosis of HP. There were 67 (83.8%) patients with the ectopic pregnancy in the uterine adnexa and 13 (16.3%) patients with the ectopic pregnancy in the uterine horn/stroma. There were 65 (81.2%) patients with pelvic effusion. The ultrasound signs showed that there were 32 (40.0%) patients with the adnexal or cornual mass, 4 (42.5%) patients with the gestational sac or gestational germ and 14 (17.5%) patients with the fetal heart and the fetal heart tube pulsation. All the patients had undergone laparoscopic surgery, of which, there were 9 (11.3%) patients with severe complications and 6 (7.5%) patients with the converted to open surgery. After surgery, there were 50 (62.5%) patients with spontaneous delivery, 21 (26.3%) patients with cesarean section and 9 (11.3%) patients with spontaneous abortion. Conclusion：Transvaginal color Doppler ultrasonography is the main measure for diagnosing HP of the patients after IVF-ET, and the diagnostic coincidence rate of which is nearly 90%, which has certain guiding significance for treating the patients with HP in the clinical practice.
