Abstract
Objective:To explore the effect and clinical value of B ultrasound in diagnosis of previous cesarean scar defect(PCSD).Method:58 cases of cesarean section in our hospital from February 2014 to February 2018 were selected as the research subjects,B ultrasound examination was performed.According to PCSD criteria,they were divided into study group(PCSD) and control group(complete scar of uterine wall). The B ultrasound examination related parameters and uterine location of two groups were compared,the relative parameters of uterine wall scar defect were compared between different cesarean section times and position of uterus in PCSD group.Result:A total of 39 cases of PCSD were detected by B ultrasonography,and the detection rate was 67.24%.The endometrial thickness,dominant follicle diameter,uterine length,anterior and posterior uterine diameter,uterine transverse diameter,scar to cervical orifice distance in two groups were compared, the differences were not statistically significant(P>0.05).The anterior position of uterus in study group was less than that of control group,the posterior position of uterus was more than that of control group,the difference was statistically significant( χ2=14.863,P=0.000).The relative parameters of uterine wall scar defect between different cesarean section times and position of uterus in PCSD group were compared,the differences were not statistically significant(P>0.05).Conclusion:B ultrasonography is an ideal and reliable clinical diagnostic method for PCSD pregnant women,it has a high detection rate and can provide valuable reference for disease diagnosis,curative effect evaluation and prognosis judgment.The risk of PCSD in women with posterior uterus is significantly higher than that in women with anterior uterus,which is a major risk factor for PCSD.关键词
