摘要
目的分析粘连性胎盘(PA)和植入性胎盘(PI)植入的MRI特征,探讨其在产前诊断中的应用。方法选取2016年1月至2020年5月胎盘植入患者70例,根据胎盘植入类型分为PA组粘连性胎盘植入37例,PI组植入性胎盘植入33例。回顾性分析其临床资科及MRI征象。结果PA组和PI组的术中出血量及有无子宫全切差异有统计学意义(P<0.05),年龄、剖宫产次、流产次数、产前阴道流血、腹痛、前置胎盘差异无统计学意义(P>0.05);MRI征象中胎盘内T2低信号带、胎盘局限性隆起、胎盘后低信号带中断/消失差异有统计学意义(P<0.05),子宫肌层变薄/中断、膀胱壁毛糙/中断、胎盘局部外生性团块、胎盘床异生血管差异无统计学意义(P>0.05)。结论胎盘内T2低信号带、胎盘局限性隆起、胎盘后低信号带中断/消失有助于产前鉴别胎盘植入类型。
Objective To analyze the MRI features of adhesive placenta accreta and placenta increta,as well as its application in prenatal diagnosis.Methods A total of 70 patients with placenta accreta in the Taizhou Hospital of Wenzhou Medical University from January 2016 to May 2020 were selected.According to the depth of placenta,they were divided into 37 cases of adhesive placenta accreta in the PA group and 33 cases of placental increta in the PI group.The clinical data and MRI features were retrospectively analyzed.Results There were statistically significant differences in intraoperative blood loss and total hysterectomy between the PA group and the PI group(P<0.05),while there were no statistically significant differences in age,number of cesarean sections,number of abortions,prenatal vaginal bleeding,abdominal pain,placenta previa(P>0.05).In MRI features,there were statistically significant differences in intraplacental dark T2 bands,uterine/placental bulge,loss of low T2 retroplacental line(P<0.05),while there were no significant difference in myometrial thinning/disruption,bladder wall interruption,focal exophytic placental mass,and abnormal vasculature of the placental bed(P>0.05).Conclusion The intraplacental dark T2 bands,uterine/placental bulge,loss of low T2 retroplacental line are helpful to distinguish the type of placental implantation before delivery.
