198.Hepatic Vascular Shunt(2)（肝血管分流）

Among hepatic tumours, AP shunts are most commonly identified in patients with hepatocellular carcinoma (HCC). They are also commonly seen in cirrhosis, especially after a portocaval shunt operation. These shunts are typically wedge-shaped, with or without internal linear branching structures in the arterial phase, and are iso- to slightly hyperattenuating during the portal venous phase. However, a follow-up radiological study may be required to exclude the possibility of a coexistent tumour.

在肝脏肿瘤中，动门脉分流最常见于肝细胞癌的患者。也可见于肝硬化患者，特别是行门腔静脉分流术后。这些分流呈典型的楔形，动脉期内部伴或不伴线样的分支结构，门脉期等/稍高密度。但之后要进行随访检查，排除伴发肿瘤的可能性。

Tumour thrombi are seen most commonly in patients with HCC (Figure 4) and to a lesser extent in patients with cholangiocarcinoma or metastases, and also cause AP shunting. Trauma-related AP shunts may occur secondary to penetrating trauma, and can be caused by a liver biopsy or by percutaneous biliary catheterisation. Radiological imaging-guided intervention, such as embolisation, is performed if there is rapid development of life-threatening portal hypertension or high-output cardiac failure. If embolisation fails, surgery is often necessary.

肿瘤栓塞在肝细胞癌的患者中最常见，在小部分胆管细胞癌和转移的患者中也可出现，常导致动门脉分流。与创伤相关的动门脉分流可继发于穿刺伤，肝活检或者经皮胆汁引流。若出现危及生命的门脉高压或者高输出型心衰，则需进行影像引导下介入，比如栓塞。若栓塞失败，则需手术。
