目的探讨彩色多普勒血流显像(CDFI)在剖宫产术后子宫瘢痕妊娠(CSP)诊治中的价值。方法回顾性选取2013年7月-2016年7月该院收治的45例CSP患者作为观察组,并选取同时期45例剖宫产术后正常妊娠患者作为对照组。回顾性分析两组患者相关超声指标,评估CDFI在CSP诊治中的价值。结果观察组患者肌层厚度(4.25±1.63)mm、血流阻力指数(RI)(0.51±0.25)均显著小于对照组[(8.81±2.48)mm、(0.66±0.14)],差异有统计学意义(t=10.301、3.214,P<0.05);观察组CSP患者声像学主要表现为3种类型,观察组患者均于妊娠囊周边观察到来自子宫切口肌层的血流信号;观察组患者依据肌层分级不同,分别给予不同治疗方案,最终均获得治愈。结论既往有剖宫产史孕妇需注意CSP可能,CDFI在CSP诊治中可发挥重要价值。
Objective To investigate the value of color Doppler flow imaging (CDFI) in the diagnosis and treatment of uterine scar pregnancy (CSP) after cesarean section. Methods 45 CSP patients admitted from July 2013 to July 2016 in our hospital were retrospectively selected as observation group. 45 pregnant women with normal pregnancy after cesarean section were selected as the control group. Retrospective analysis of the two groups of patients related to ultrasound indicators to assess the value of CDFI in the diagnosis and treatment of CSP. Results The thickness of muscular layer (4.25 ± 1.63) mm and RI (0.51 ± 0.25) in observation group were significantly lower than those in control group [(8.81 ± 2.48) mm, (0.66 ± 0.14), respectively] (T = 10.301,3.214, P <0.05). There were three types of echocardiography in CSP patients in the observation group. The blood flow signals in the muscular layer of the incision of the womb were observed in the observation group. In the observation group, According to different muscle grading, were given different treatment options, and ultimately were cured. Conclusions Pregnant women with previous history of cesarean section should pay attention to the possibility of CSP and CDFI may play an important role in the diagnosis and treatment of CSP.
