The clinical analysis of 156 cases of placenta increta

Yurong Zhao and Xufang He

Objective: Morbidly adherent placentation (MAP), which includes placenta accreta, increta, and percreta, is a serious complication of pregnancy associated with perinatal massive hemorrhage, intensive care unit admission, and cesarean hysterectomy. MAP complicates approximately 1 in 500 to 1,000 pregnancies. This rate has increased up to 10-fold in the past 20 years, attributed largely to rising rates of cesarean deliveries. The reported incidence in the United States increased from 0.08% in 1985 to 0.3% in 2005.Domestic incidence of MAP has increased by 10 times nearly 30 years, with the increasing of abortion, hysteroscopy surgery, cesarean section rate。The steadily increasing rate of placenta previa and caesarean section may result in an increased number of patients with abnormal placentation. Additional risk factors for MAP include uterine operation, caesarean delivery, advanced maternal age (≥35 years), multiparity, and a history of endometrial ablation. The occurrence of placenta percreta will significantly affect the outcome of pregnancy, causing postpartum haemorrhaging, uterine perforation, and other serious complications; additionally, it can even endanger the lives of pregnant women and their foetuses. This study is to discuss the risk factors, etiology, diagnosis, treatment of placenta increta. To improve the quality of obstetrics.
