B超用于剖宫产子宫切口瘢痕缺陷临床诊断价值研究

Clinical diagnosis value of B ultrasound for previous cesarean scar defects

目的探讨和分析剖宫产子宫切口瘢痕缺陷(PCSD)的B超诊断情况,同时研究瘢痕形成的相关危险因素。方法对本院收治的99例剖宫产产妇采用B超检查,并根据PCSD定义将其分为对照组(宫壁瘢痕完整)和试验组(宫壁瘢痕缺损)。比较分析两组产妇剖宫产次数和阴道试产等情况。结果采用B超检出PCSD的概率为61.62%(61/99)。试验组产妇出现的瘢痕位置距宫颈内口(5.69±1.89)mm,与对照组[(6.49±2.20)mm]比较差异显著(P<0.05)。试验组产妇后位子宫占65.57%(40/61),与对照组[31.58%(12/38)]比较差异显著(P<0.05)。而两组产妇年龄、阴道试产以及剖宫产次数比较无显著差异(P>0.05)。结论采用B超检查诊断PCSD检出率高,瘢痕位置与宫颈内口较近,且引发PCSD的主要危险因素为后位子宫。

Objective Discussion and analysis of cesarean section uterine incision scar defect（PCSD） B ultrasound diagnosis of the situation, and the related risk factors of formation of scar. Method 99 cases of cesarean section were applied B ultrasound examination in our hospital according to the definition of PCSD, patients were divided into control group（uterine wall scar complete） and test group（uterine wall scar defect）, compared and analysed of two groups of maternal cesarean, vaginal delivery and other conditions. ResultWith probability B ultrasound detection of PCSD was 61.62%（61/99）. Test group maternal scar position from the endocervix（5.69±1.89） mm, and control group [（6.49±2.20） mm] had significant difference（P〈0.05）. Test group parturient, retroposition of uterus accounted for 65.57%（40/61）, and control group [31.58%（12/38）] had significant difference（P〈0.05）. And the two group of women in age, vaginal delivery and cesarean section number had no significant difference（P〉0.05）. Conclusion Using PCSD, the detection rate of ultrasonography in the diagnosis is high. Scar position and in the cervix mouth is near. The main risk factors causing PCSD is retro position of uterus.
