Objective: To analyse the clinical data of and provide a reference for the care and perinatal health care of twin pregnancy patients with complete hydatidiform mole and a coexistent foetus (CHM & CF).
Methods: We searched the China National Knowledge Infrastructure (CNKI) and Wanfang and VIP databases to comprehensively collect clinical studies on the “clinical characteristics of complete hydatidiform mole and coexisting foetal twin pregnancy”. Patients’ data were extracted from the literature, and 60 patients were divided into Group A (live newborns not delivered, 47) and Group B (live newborns delivered, 13). The clinical characteristics of the two groups were compared to explore the pregnancy outcomes and influencing factors of persistent gestational trophoblastic disease (pGTD) in patients with CHM & CF.
Results: The gestational week of diagnosis (Odd Ratio (OR)=0.203, 95% Confidence Interval (CI)=0.055– 0.753) and number of complications (OR=0.328, 95% CI=0.135– 0.793) were found to be independent influencing factors of pregnancy outcomes in patients with CHM & CF (p < 0.05). Ovulation induction therapy (OR=2.333, 95% CI=0.561– 9.708), preeclampsia (OR=75.000, 95% CI=11.041– 509.486) and the number of complications (OR=4.768, 95% CI=1.914– 11.875) were the independent influencing factors of developing pGTD (p < 0.05).
Conclusion: Pregnancy should not be terminated immediately after the early detection of CHM & CF, and multiple factors should be considered. Preeclampsia may indicate a poor prognosis, and ovulation induction may increase the incidence of pGTD. Targeted nursing and psychological nursing should be carried out according to the clinical symptoms of the patients.
