Abstract

Objective
Our goal was to review outcomes of patients with heterotopic pregnancies who under went surgical treatment.
Methods
From January 1, 2005 to December 31, 2021, 27 women with heterotopic pregnancies who had undergone surgical treatment were enrolled. We investigated pregnancy outcomes based on clinical records and follow-up telephone interviews. Three of the 27 patients were excluded because we were unable to contact them.
Results
Of the 24 patients included in the study, 17 underwent salpingectomies for tubal pregnan cies, 5 underwent wedge resections for cornual pregnancies, and 1 underwent a unilateral salpingooophorectomy for ovarian pregnancy. One patient with a suspected heterotopic cervical pregnancy had undergone extraction with forceps and curettage under abdominal ultrasound guidance. Three patients had spontaneous abortions after treatment for heterotopic pregnancies (2 tubal pregnancies, one cervical pregnancy). Twenty-one of 24 patients had heterotopic pregnancies that occurred after assisted reproductive technology. Three cases were heterotopic pregnancies that occurred without reproductive interventions. Among 24 patients who underwent surgical treatment, 18 patients (75.0%) had full-term deliveries.
Conclusion
There were no hospitalizations due to preterm labor, and 21 deliveries (87.5%) were either late preterm or full-term. There were no fetal abnormalities or maternal complications. Although the development of assisted reproductive technologies has increased the incidence of heterotopic pregnancy, the outcomes of heterotopic pregnancies are generally good.
