前置胎盘、胎盘粘连、胎盘植入与人工流产的关系

Relation of Placenta Previa,Placenta Adhesion and Placenta Implantation With Artificial Abortion

目的探讨前置胎盘、胎盘粘连、胎盘植入与人工流产的关系。方法采用回顾性自然研究方法,收集我院1999年1月-2006年12月的产科分娩病例共4628例,按人工流产次数(0、1、2、≥3次)分为A、B、C、D四组,统计每组前置胎盘、胎盘粘连、胎盘植入的发生率,并进行统计学分析。结果A、B、C、D四组的发病率分别为2.9%、7.4%、10.8%、32.0%,经统计学处理,差异有高度显著性(χ2=448.57,P<0.01),且以胎盘粘连的发生率较高(χ2=15.78,P<0.05)。结论无人工流产者前置胎盘、胎盘粘连的发生率最低,且无胎盘植入发生,随着人工流产次数的增加,前置胎盘、胎盘粘连的发生呈明显上升趋势,多次人工流产可发生胎盘植入。

Objective To study the relationship of placenta previa, placenta adhesion and placenta implantation with artificial abortion. Methods Altogether 4,628 patients＇ data were collected by using retrospective natural research method in our hospital from January 1999 to December 2006. According to the frequency of artificial abortion （0, 1, 2, ≥3 times）, they were divided into groups of A, B, C and D, the incidences of placenta previa, placenta adhesion and placenta implantation were performed statistical analysis. Results The incidences of these diseases from groups of A, B, C and D were 2.9%, 7.4%, 10.8% and 32.0% respectively, and showed statistically significant difference （X2 = 448.57, P〈 0.01）, moreover with the highest incidence of placenta adhesion （X2 = 15.78, P〈 0.05）. Conclusions Without artificial abortion history, the occurrence rates of placenta previa and placenta adhesion are lower, and placenta implantation would not occur. Along with the increased frequency of artificial abortion sessions, the incidences of placenta previa and placenta adhesion significantly increase. Repeated artificial abortion sessions can induce the occurrence of placenta implantation.
