凶险型前置胎盘孕妇肌酸激酶检测的产前诊断价值

目的通过比较孕晚期凶险型前置胎盘孕妇和正常妊娠孕妇血清中肌酸激酶的差异,探讨其用于凶险型前置胎盘合并胎盘植入产前诊断的价值。方法回顾性分析2012年6月至2013年6月江西省妇幼保健院凶险型前置胎盘单胎孕妇92例,其中合并胎盘植入者38例,归入凶险型前置胎盘合并胎盘植入组,其余54例归入未合并胎盘植入组,再随机抽取同期分娩的既往有剖宫产史,本次为正常妊娠的孕妇50例作为对照组,比较三组孕妇血清肌酸激酶水平的差异。结果凶险型前置胎盘合并胎盘植入组CK数值为(128.6±19.8)U/L,未合并胎盘植入组为(67.7±21.2)U/L,单纯剖宫产史组为(65.1±20.3)U/L。凶险型前置胎盘合并胎盘植入时,孕妇血清肌酸激酶水平明显升高,差异具有统计学意义。而在中央型前置胎盘、部分型前置胎盘和边缘型前置胎盘中,肌酸激酶分别为(80.3±38.2)U/L、(77.1±36.0)U/L、(79.6±29.7)U/L,三者差异无统计学意义。结论孕妇血清肌酸激酶的测定对凶险型前置胎盘合并胎盘植入的产前预测有价值,与前置胎盘的类型无关。

PRENTAL DIAGNOSIS OF CREATINE KINASE DETECTION IN PERNICIOUS PLACENTA PREVIA

Objective：Through comparing the content difference of serum creatine kinasebetween pregnant women with pernicious placenta priva and the normal ones to investigate its value in prenatal diagnosing pernicious placenta priva with placenta accreta.Methods：A total of 92 patients of pernicious placenta priva were retrospectively analyzed in Maternal and Child Care Service Centre of Jiangxi Province from June 2012 to June 2013, among them, 38 cases of pernicious placenta priva with placenta accrete after operation were classified into the study group with placenta accreta, others into the study group without placenta accrete, then 50 women having caesarean section ever but normal pregnance this time into the control group. The levels of serum creatine kinase among three groups were compared.Results：The levels of creatine kinase in study groups with placenta accreta, without placenta accreta and controls were （128.6 ± 19.8） U/L, （67.7 ± 21.2） U/L and （65.1 ± 20.3） U/L respectively. The level of the study group with placenta accreta was the highest of all. But the levels for central placenta priva, partial placenta priva and marginal placenta priva were（80.3 ± 38.2） U/L,（77.1 ± 36.0） U/L and（79.6 ± 29.7） U/L respectively, the difference among them was not statistically significant. Conclusion：The level of creatine kinase may be helpful to predict placenta accreta prenatally, which is unrelated to the type of placenta accreta.
