【摘要】 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。更多还原

【Abstract】 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 were defined by using Michels classification. Results The total accuracy for detecting hepatic artery anatomy types by 2D-CEUS was 40.0% (12/30),while 83.3% (25/30) by 2D-CEUS. For convention anatomy types the accuracy on 2D-CEUS and 3D-CEUS were 40.9%(9/22)and 90.9%(20/22),respectively. The difference was statistically significant (P<0.05). For anatomy variants types the accuracy on 2D-CEUS and 3D-CEUS were 37.5%(3/8)and 62.5%(5/8),respectively. No significant difference between these two methods was observed. Conclusion 3D-CEUS was a new method in diagnosis of hepatic arteries anatomy types with practical clinical value in evaluation of the living liver donors.更多还原
