Digital subtraction angiography (DSA) and reconstructed image of computed tomography during angiography. A. Angiography shows a tumor stain (arrow) at the hepatic segment 6 with bold feeding artery. An early drainage vein from the tumor is detected at hepatic arterial phase. B. Blood flow of drainage vein is gradually clear (arrow). C. Contrast medium flows intensely into inferior vena cava (arrows). There were many small poolings of enhanced medium, which are suspected as peripheral blood dilatation, around the whole liver. D. Three dimension reconstructed image of computed tomography during arterial angiography. There is an efferent vessel from the tumor (arrow).
