Maternal outcomes in pregnant women with pernicious placenta previa / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the maternal outcomes of pregnant women with pernicious placenta previa (PPP).</p><p><b>METHODS</b>Clinical data of 470 patients with placenta previa admitted in Women's Hospital Zhejiang University School of Medicine from August 2012 to August 2014 were collected and retrospectively analyzed. The patients were divided into pernicious group(n=101) and non-pernicious group(n=369) according to the history of cesarean section and location of placenta attached to the uterine. The general profiles, maternal outcomes of two groups were compared.</p><p><b>RESULTS</b>The age, gravidity and rate of recurrent cavity surgery of pernicious group [(32.5 ± 4.1) y, 3.4 ± 1.2, 28.7%] were higher than those of non-pernicious group [(30.7 ± 4.5) y, 2.1 ± 1.4,13.6%] (P<0.05). The gestational age of pernicious group was (35.6 ± 2.7) weeks, less than that of non-pernicious group [(36.7 ± 2.7) weeks, P<0.001]. Rate of postpartum massive hemorrhage, rate of blood transfusion, rate of placental implantation and hysterectomy in pernicious and non-pernicious group were 29.7%, 35.6%, 27.7%, 11.9% and 8.1%, 10.8%, 5.7%, 0.8%, respectively (P<0.05). Multiple regression analysis showed that placenta accrete was significantly associated with postpartum massive hemorrhage in pernicious group (P<0.05).</p><p><b>CONCLUSION</b>The awareness of the danger of pregnant women with PPP before operation and paying more attention to antenatal care are key measures to decrease the adverse maternal outcomes of pregnant women with placenta previa.</p>
