OBJECTIVE: To investigate the value of ultrasonography in the diagnosis of heterotopic pregnancy and the follow-up. METHODS: A retrospective analysis of 50 cases of clinically diagnosed heterotopic pregnancy in our hospital was performed, the clinical characteristics and ultrasonographic manifestations of the patients were summarized, the reasons for initial ultrasound missed diagnosis and misdiagnosis were analyzed, and the pregnancy outcomes were followed up. RESULTS: Among the 50 cases, the initial ultrasound diagnoses of intrauterine pregnancy were all gestational sac type, 32 cases of ectopic pregnancy were located in the fallopian tube, and 10 cases were located in the uterine horn, 1 case at cervix, and 1 case at caesarean section scar. Forty-one cases were consistent with surgery and/or pathology, representing initial ultrasound diagnosis coincidence rate of about 82%. Six cases were missed in the initial ultrasound examination (12%), and three cases were misdiagnosed (6%). The maximum diameter of the intrauterine gestational sac was 9-48 mm, the average was about 24.90 ± 9.56 mm, the maximum diameter of the ectopic pregnancy gestational sac or mass was 11-63 mm, and the average was about 31.45 ± 13.82 mm (p < 0.05). Intrauterine pregnancy outcomes were followed up, 45 patients with complete data and 5 patients were lost to follow-up. The follow-up rate was about 90%. CONCLUSION: Combining the patient's medical history and clinical characteristics can reduce missed di...
