目的分析凶险型前置胎盘对孕产妇的危害性,提高对凶险型前置胎盘的认识。方法比较19例凶险型前置胎盘与74例非凶险型前置胎盘的临床资料。结果凶险型前置胎盘组产后出血发生率、术中出血量、胎盘植入发生率、子宫切除率均明显高于非凶险型前置胎盘组(均P<0.05)。结论多次妊娠分娩或流产是导致凶险型前置胎盘发生的高危因素之一;多普勒仍是目前诊断胎盘植入的有效手段;介入治疗可应用于保守治疗。
Objective To analyze the dangers of dangerous placenta previa on pregnant women and improve the understanding of dangerous placenta previa. Methods The clinical data of 19 cases of dangerous placenta previa and 74 cases of non-dangerous placenta previa were compared. Results The incidence of postpartum hemorrhage, intraoperative blood loss, incidence of placenta accreta and hysterectomy were significantly higher in patients with precardial placenta previa (all P <0.05). Conclusions Multiple pregnancy and childbirth or miscarriage are one of the risk factors for the occurrence of dangerous placenta previa. Doppler is still an effective method to diagnose placenta accreta at present. Interventional therapy can be used in conservative treatment.
