【摘要】：目的剖宫产瘢痕妊娠(CSP)近年发病率呈上升趋势,误诊或治疗不当可致严重后果。本文拟分析CSP的超声与MRI特征,为临床选择影像诊断手段提供依据。资料与方法回顾性分析经手术及病理确诊的58例CSP患者,术前均行经阴道或联合经腹彩色多普勒超声检查,其中31例行MRI检查,分析CSP各型的影像图像特征及诊断准确率。结果彩色多普勒超声正确诊断48例(82.8%),包括外生型20例(95.2%,20/21)、内生型18例(90.0%,18/20)、包块型10例(58.8%,10/17);MRI正确诊断27例(87.1%),包括外生型8例(100.0%,8/8)、内生型4例(66.7%,4/6)、包块型15例(88.2%,15/17)。结论超声与MRI检查对CSP的诊断准确率接近,临床可首选超声检查;超声发现为包块型CSP而难以确诊时可联合MRI检查,以提高诊断准确率。
[Abstract]:Objective in recent years, the incidence of cesarean scar pregnancy (CSP) is on the rise, and misdiagnosis or improper treatment can result in serious consequences. This paper aims to analyze the characteristics of ultrasound and MRI in CSP. Materials and methods 58 patients with CSP confirmed by operation and pathology were examined by transvaginal or transabdominal color Doppler ultrasonography before operation, 31 of them underwent MRI examination. Results 48 cases of CSP were correctly diagnosed by color Doppler ultrasound, including 20 cases of exogenous type with 95.2% 20 / 21, 18 cases of endogenous type with 90.018 / 20, 10 cases of mass type with 10% 10 / 17, 27 cases with 87.1D, including 8 cases of ectogenic type, 10 cases with 10% 10 / 17, 10 cases with mass type, and 8 cases with exogenetic type, including 8 cases with exogenetic type. There were 4 cases of endogenetic type (66.7%) and 15 cases of mass type (15 cases). Conclusion the diagnostic accuracy of ultrasound and MRI for CSP is close to that of 15 / 17. Ultrasonic examination is the first choice in clinic, and it can be combined with MRI to improve the diagnostic accuracy when it is difficult to be diagnosed as a lump type CSP.
