A Retrospective Study of Placenta Accreta, Percreta, and Increta in Peripartum Hysterectomies in a Tertiary Care Institute in Northeast India.

Abstract

Background: Abnormal placentation such as placenta accreta, increta, and percreta are frequent causes of post-partum hemorrhage, which results in maternal morbidity and mortality. A previous history of cesarean section, placenta previa, and pre-eclampsia are the important risk factors for abnormal placentation. A reliable antenatal diagnosis and planned surgical approach can reduce the incidence of maternal morbidity and mortality from massive hemorrhage.Aim: To study the incidence of abnormal placentation and the association of various risk factors with abnormal placentation.Material and methods: A retrospective study over a period of eight years in patients with peripartum hysterectomies due to abnormal placentation presenting with massive hemorrhage.Results: We received a total of 10 emergency hysterectomy specimens during an eight‑year period. Of the cases, placenta accreta accounted for 40% (4/10), increta up to 40% (4/10), and percreta 20% (2/10). Analysis of these findings with parity showed 20% of the women were uniparous (2/10), and 80% were multiparous (8/10). Risk factor analysis showed previous cesarean sections in 40% (4/10), placenta previa in 50% (5/10), and pre‑eclampsia in 10% (1/10).Conclusion: The present study highlights the incidence of abnormal placentation in a tertiary care institute in Northeast India. Placenta accreta and increta constituted the major forms of abnormal placentation. Multiparous women with placenta previa followed by previous lower segment cesarean section were more at risk of having abnormal placentation. These findings will guide in antenatal care by risk prioritization and management planning of these patients.
