Comparison between emergent and elective delivery in women with placenta accreta

Abstract

Objective: To identify possible predictive factors associated with emergent delivery of antenatally diagnosed placenta accreta and to estimate association between emergent delivery and adverse maternal outcomes in comparison to elective delivery.

Methods: A retrospective study of all patients with placenta accreta diagnosed antenatally and confirmed pathologically, who were delivered between 2000 and 2010. Baseline characteristics and outcomes of emergent deliveries were compared with elective deliveries.

Results: A total of 48 women met inclusion criteria, of which 24 (50%) were delivered emergently. 79.2% of emergent deliveries were preceded by antenatal bleeding (p = 0.0005), and 62.5% were preceded by recurrent bleeding (p = 0.001). Comparison of elective and emergent deliveries revealed no clinical significant difference in maternal outcome.

Conclusions: Antenatal bleeding is associated with an increased risk of emergent delivery. Emergent delivery in a tertiary care facility with immediate access to blood bank and ICU capabilities does not appear to be associated with an increased risk of adverse maternal outcomes. Consequently, some patients may be candidates for delivery later than 34 weeks of gestation.
