作者报道3例在动脉门静脉造影CT(CTAP)上出现的由迷走胃右静脉引流(AGVD)所致的肝Ⅱ/Ⅲ节段假性病灶。例1为59岁男性,系肝细胞癌复发伴有与C型肝炎有关的肝硬化,1年前曾用碘油及明胶海绵颗粒作过经导管化学栓塞。CTAP上,肝左叶后缘(Ⅱ节段)显示直径2cm的楔形灌注缺损区,而在常规CT、超声或MRI上,该区域未见确切异常。肝总动脉造影的静脉期见到一支迷走的胃静脉。CT上当对比剂灌注到肝总动脉时,看到一支迷
The authors reported three cases of pseudohepatic lesions of the hepatic segment II / III caused by vagal veins drainage (AGVD) in 3 cases of arterial portal venography (CTAP). Example 1 A 59-year-old male with recurrent hepatocellular carcinoma with cirrhosis associated with hepatitis C was treated with transcatheter chemoembolization with lipiodol and gelatin sponge particles 1 year prior. At the CTAP, the posterior margin of the left lobe of the liver (segment II) showed a wedge-shaped perfusion defect of 2 cm in diameter, whereas there was no exact abnormality in this area on conventional CT, ultrasound or MRI. The hepatic artery angiography of the veins see a vagal veins. When CT contrast agent perfusion to the common hepatic artery, I saw a fan
