Ninety-seven patients with hepatocellular carcinoma had duplex scanning from the patent or residual portal lumen and comparative angiography. Duplex ultrasonography identified five of nine patients with angiographic evidence of arterioportal shunting. Furthermore, Doppler results indicated the presence of the shunt in one patient without angiographic evidence. Duplex scanning from the portal lumen may be useful in the detection of arterioportal shunting. This procedure can be used to evaluate the hemodynamic change of the recipient portal vein under natural physiologic conditions. However, small shunts without hepatofugal portal blood cannot be detected by this procedure.
97例肝细胞癌患者接受了经开放或残留门静脉腔的双功扫描及对比血管造影检查。双功超声检查在9例有动脉门静脉分流血管造影证据的患者中发现了5例。此外，多普勒检查结果显示1例无血管造影证据的患者存在分流。经门静脉腔的双功扫描可能有助于检测动脉门静脉分流。该检查可用于评估自然生理条件下受体门静脉的血流动力学变化。然而，该检查无法检测到无肝外门静脉血流的小分流。
