【摘要】：目的:探讨剖宫产后子宫切口瘢痕妊娠(CSP)的MRI及经阴道超声影像表现及特征,通过对照分析两种诊断方法对剖宫产子宫瘢痕妊娠的诊断价值。方法:回顾性分析手术证实的26例CSP患者资料,26例均行经阴道超声检查,且均在1周内同时行MRI检查。将MR及超声影像表现与手术及病理结果进行比较,总结其影像特征。结果:26例中,经阴道超声诊断正确20例(76.92%),误诊6例(23.08%),经阴道超声诊断准确率为76.92%;MRI准确诊断25例(96.15%)为子宫切口瘢痕妊娠,误诊1例(3.85%)。超声在判断卵黄囊结构及其胚芽是否存活优于MRI。在孕囊与瘢痕的关系、孕囊浸润子宫肌层程度、孕囊及宫腔内出血的评价方面,MRI较超声有优势。超声与MRI诊断剖宫产切口妊娠的正确率比较,差异无统计学意义(χ2=3.467,P0.05)。结论:阴道超声及MRI均可准确诊断早期瘢痕妊娠,对阴道彩超难以确诊的病例,应进行MRI检查以明确诊断,避免漏诊。
[Abstract]:Objective : To investigate the diagnostic value of CT and vaginal sonographic imaging of cesarean scar pregnancy ( CSP ) after cesarean section . Methods : Twenty - six patients with cesarean scar pregnancy were examined by contrast analysis . The results were as follows : 20 cases ( 76.92 % ) were diagnosed correctly by ultrasound , 6 cases ( 23.08 % ) were misdiagnosed as uterine incision scar pregnancy and 1 case ( 3.85 % ) were misdiagnosed . Conclusion : Transvaginal ultrasound and MRI can accurately diagnose early scar pregnancy , and it is difficult to diagnose the vagina color . MRI should be performed to diagnose and avoid missed diagnosis .
