超声造影与彩色多普勒超声诊断异位妊娠的对比研究

Comparative study of contrast-enhanced ultrasound and color Doppler flow imaging in diagnosis of ectopic pregnancy

目的探讨超声造影与彩色多普勒超声在诊断异位妊娠中的应用价值。方法以手术病理为诊断标准,对比分析超声造影与彩色多普勒超声诊断异位妊娠的准确性。结果 124例患者,手术证实109例为异位妊娠,15例为宫内孕。超声造影准确诊断异位妊娠107例,漏诊2例,异位妊娠的超声造影表现为附件区可见管样增强回声,其内可见不规则造影剂充填区,35例出现Donut征。超声造影诊断异位妊娠的敏感性、特异性和准确性分别为98.2%、80.0%和96.0%。彩色多普勒超声准确诊断异位妊娠94例,漏诊15例,彩色多普勒超声诊断异位妊娠的敏感性、特异性和准确性分别为86.2%、53.3%和81.4%。结论超声造影诊断异位妊娠的准确性高于彩色多普勒超声,具有较好的临床应用价值。

Objective To investigate the application value of contrast-enhanced ultrasound （CEUS）and color Dopple flow imaging （CDFI）in the diagnosis of ectopic pregnancy （EP）.Methods The accuracy of CEUS and CDFI in diagnosing unruptured ectopic pregnancy was analyzed using pathology as the golden criteria. Results One hundred and twenty-four patients received operation. One hundred and nine of them were EP,15 of them were intrauterine pregnancy. One hundred and seven of them were comfirmed as EP by CEUS,the other two were missed diagnosis. CEUS showed tube-like enhancement and the irregular contrast agent filling area in the tube,35 patients displayed Donut sign. The sensitivity,specificity,accuracy of CEUS were 98.2%, 80.0%,96.0% and those of CDFI were 96.2%,46.7%,81.4%,respectively. Conclusion The accuracy of CEUS for diagnosing EP is much higher than that of CDFI.
