Abstract Objective: To evaluate the clinical value of three dimensional color power angiography(3D-CPA) applied in the drainage of the third hepatic hilum in Budd-Ｃhiari syndrome(BCS). Methods: Sixty cases with BCS underwent 3D-CPA for demonstrating draining vessels of the third hepatic hilum including inferior right hepａtic veins and caudal-lobe veins. The structures of hepatic vein and communicating branches were observed. ATL HDI 3500 was used with transducer 3.5MHz. Results: Ninety-six of 139 rami affected hepatic veins were not completely obstructive in this group. All of the occlusive parts and communicating branches of the 96 hepatic veins mentioned above were displayed distinctly on 3D-CPA imaging. Blood drained through inferior right hepatic veins and caudal-lobe veins were 43 and 71 rami respectively. The spatial relationship of anatomic structures of the 2nd and 3rd hepatic hilum was displayed clearly on 3D-CPA imaging. There was no blood signal in the obstructive parts of the hepatic veins but blood signals replenished the communicating branches bridging from the affected hepatic veins to the inferior right hepatic and/or caudal-lobe veins. Conclusion: The anatomic structures and blood drainage state of the third hepatic hilum are visulized more directly on 3D-CPA images which provide more information for treating BCS before operation.
