A case series: thirty-three cases with heterotopic pregnancy after assisted reproductive technology

Category	Detail
Condition	Heterotopic Pregnancy
Key Mechanisms	Involves multiple gestational sacs implanted at distinct intrauterine and extrauterine sites, often associated with assisted reproductive technology.
Target Population	Patients with heterotopic pregnancy diagnosed via assisted reproductive techniques.
Care Setting	Reproductive Medicine Center, First Hospital of Jilin University

66.67% of patients achieved viable ongoing intrauterine gestation or live birth.
Ultrasonic markers such as fetal cardiac activity significantly predict favorable pregnancy outcomes (OR = 22.00).
No significant differences in outcomes between blastocyst and cleavage-stage embryo transfers.
Better intrauterine embryonic development correlates with higher odds of favorable outcomes (OR = 28.75).
Laparoscopic resection is a common therapeutic strategy for heterotopic pregnancy.

Diagnosis confirmed by transvaginal sonography or surgical pathological examination.

Laparoscopic resection of ectopic gestational lesions is the main therapeutic strategy.

Close ultrasound monitoring may allow for conservative management in selected patients.

Risk of rupture of the ectopic lesion is positively correlated with gestational age.

Patients diagnosed with heterotopic pregnancy.

Sequential identification of intrauterine gestational sac and fetal cardiac activity is crucial for predicting outcomes.

Utilize serial plasma human chorionic gonadotrophin (HCG) monitoring for diagnosis.
Consider the timing of ultrasound examinations for optimal diagnosis and management.
