三维超声造影评价肝动脉解剖分型的价值

目的探讨三维超声造影评价肝动脉解剖分型的应用价值。方法对10例上腹部肿瘤患者和20例拟捐献供肝的活体肝移植供体的肝脏行二维超声造影和三维超声造影检查。肝动脉解剖分型参照Michels分型标准,以CTA/MRA/DSA/手术为对照,比较二维超声造影与三维超声造影判断肝动脉解剖分型的符合率。结果二维超声造影与三维超声造影判断肝动脉解剖分型的总符合率分别为40.0%(12/30)和83.3%(25/30),两者之间的差异有统计学意义(P=0.000)。其中对于正常解剖类型,二维超声造影与三维超声造影判断符合率分别为40.9%(9/22)和90.9%(20/22),两者之间的差异有统计学意义(P=0.000);对具有解剖变异类型病例,二维超声造影与三维超声造影判断符合率分别为37.5%(3/8)和62.5%(5/8),两者之间的差异无统计学意义(P=0.196)。结论三维超声造影是评价肝动脉解剖结构及变异的新方法,可能成为CTA、MRA、DSA等的重要补充。

Clinical value of three-dimensional contrast-enhanced ultrasonography in evaluation of hepatic arteries anatomy types

Objective To assess the value of three-dimensional contrast-enhanced ultrasonography (3D-CEUS) in evaluation of hepatic arteries variants. Methods Both two-dimensional contrast-enhanced ultrasonography (2D-CEUS) and 3D-CEUS were used to assess 30 patients including living donor candidates and patients with upper abdomen tumors. The reference standard was operation or CTA or DSA or MRA,and the accuracy for detecting hepatic artery variants provided by the two methods was evaluated. Arterial anatomic types we...
