Maternal Near Miss According to World Health Organization Classification Among Women with a Hydatidiform Mole: Experience at the New England Trophoblastic Disease Center, 1994-2013

Abstract

Objective: To investigate the frequency of potentially life-threatening conditions (PLTCs) and maternal near misses (MNMs) at the New England Trophoblastic Disease Center (NETDC) in recent years, when there has been earlier diagnosis of molar pregnancy.

Study design: This study included patients with molar pregnancy at the NETDC between 1994 and 2013. Clinical and pathologic reports were reviewed. PLTC and MNM criteria and maternal deaths were searched in medical records using the World Health Organization criteria and classification.

Results: We identified 375 patients with molar pregnancy and no patient developed a MNM or maternal death. Only 6 (1.6%) had PLTCs (hemorrhage with hemodynamic instability, severe preeclampsia, respiratory distress, blood transfusion, and ICU admission).

Conclusion: We observed a low rate of PLTC and no cases of MNMs or maternal deaths related to molar pregnancy, likely due to earlier diagnosis at the NETDC in recent years.
