Multiple pregnancies with complete mole and coexisting normal fetus in North and South America: A retrospective multicenter cohort and literature review

The main regional difference in CHMCF presentation is related to a higher rate of potentially life-threatening conditions in South America. Sixty percent of the expectantly managed CHMCF delivered a viable infant, and the overall rate of GTN in this study was 46%. Elective termination of pregnancy did not influence the risk for GTN; however the need for termination due to complications and higher hCG levels were associated with development of GTN in CHMCF.
