经阴道超声与超声造影应用于早孕期瘢痕妊娠中的诊断价值分析

Diagnostic value of transvaginal ultrasound and contrast-enhanced ultrasound in early pregnancy with scar

目的分析早孕期瘢痕妊娠应用经阴道超声与超声造影诊断的价值。方法选取42例疑似早孕期瘢痕妊娠患者,患者均实施经阴道超声与超声造影检查,比较经阴道超声与超声造影不同检查方法瘢痕诊断、病理结果及诊断效能。结果经术后病理结果证实,瘢痕妊娠患者31例,非瘢痕妊娠患者11例;经阴道超声诊断:瘢痕妊娠29例,非瘢痕妊娠13例;超声造影诊断:瘢痕妊娠30例,非瘢痕妊娠12例。超声造影检查准确率、特异度及敏感度均高于经阴道超声检查(P<0.05)。结论超声造影与经阴道超声应用于早孕期瘢痕妊娠诊断中,超声造影检查的结果更接近于病理结果,且获取的超声图像较经阴道超声更为清晰,能清晰观察明确妊娠物着床位置,并体现其与子宫肌层的关系,相比经阴道超声检查具有更高的瘢痕妊娠诊断准确率、特异度和敏感度,有利于疾病的分型诊断,具有较高的应用价值。

Objective To analyze the value of transvaginal ultrasonography and contrast-enhanced ultrasound in diagnosis of scar pregnancy in early pregnancy.Methods 42 patients with suspected early pregnancy scar were selected and all of them underwent transvaginal ultrasound and contrast-enhanced ultrasound.The scar diagnosis,pathological results and diagnostic efficacy of different methods of transvaginal ultrasound and contrast-enhanced ultrasound were compared.Results The postoperative pathological results showed 31 patients with scar pregnancy and 1l patients with non-scar pregnancy.Transvaginal ultrasound diagnosis:scar pregnancy in 29 cases,non-scar pregnancy in 13 cases;Contrast-enhanced ultrasound diagnosis:scar pregnancy in 30 cases,non-scar pregnancy in 12 cases.The accuracy,specificity and sensitivity of CEUS were higher than those of transvaginal ultrasound(P<0.05).Conclusion In the diagnosis of scar pregnancy in early pregnancy,the results of CEUS and transvaginal ultrasound are closer to the pathological results,and the ultrasound images obtained are clearer than those obtained by vaginal ultrasound,which can clearly observe the implantation position of pregnancy object and reflect its relationship with the myometrium.Compared with transvaginal ultrasound,CEUS has higher diagnosis accuracy,specificity and sensitivity of scar pregnancy.It is beneficial to the classification and diagnosis of diseases and has high application value.
