Molar Pregnancy with a Coexistent Fetus following Assisted Reproductive Techniques: A Review of Literature of the Clinical Course and Sequelae

Abstract

Abstract The clinical course and sequelae of molar pregnancy pose several diagnostic and management challenges, especially conceiving after assisted reproductive technology. A review of the literature was conducted on molar pregnancy with a coexistent fetus following assisted reproductive techniques, its clinical course, and sequelae. The literature review was conducted using search terms “coexistent fetus,” “hydatidiform mole,” “twin,” “assisted conception” AND “persistent gestational trophoblastic disease (PGTD)” OR “chemotherapy” in PubMed. A literature search identified 26 reported cases conceived following assisted conception. Management guidelines for hydatidiform mole with live fetuses are very vague and do not give specificity due to the fact that it is often associated with complications and bad obstetric outcomes. It also requires continuous monitoring and follow-up in a tertiary care center anticipating disease progression to postnatal PGTD. To assess the risk of continuation of pregnancy, multicentric studies with larger sample sizes are required to have a valid finding.
