研究和探讨肝海绵状血管瘤肝动脉栓塞对胆道造成的损伤。方法 :报告 4例肝血管瘤肝动脉栓塞后引起黄疸、胆汁性肝脓肿及胆道损毁病变病例 ,并用实验大鼠肝动脉内注射乙醇复制血管栓塞剂对肝脏的损伤。结果 :其中 3例在胆汁性肝脓肿经皮引流后 ,进行肝内胆管U形管支撑及胆管空肠吻合 ,疗效较好。实验结果证实肝动脉注射血管栓塞剂无水乙醇后可以引起肝脏局部坏死 ,胆管坏死闭塞。结论 :用血管硬化剂如鱼肝油酸钠等作肝动脉的非超选择性栓塞 ,将会造成病变外正常肝和胆道的坏死 ,其治疗非常困难。并呼吁对无症状的肝血管瘤应严格选择治疗适应证。
To study and investigate the hepatic artery embolism caused by hepatic cavernous hemangiomas causing damage to the biliary tract. Methods: Four cases of hepatic hemangioma caused hepatic artery embolism caused by jaundice, biliary hepatic abscess and biliary lesions were reported. Hepatic arterial embolization was used to induce hepatic injury in hepatic artery. Results : Among them, 3 cases had biliary U-tube support and biliary-jejunal anastomosis after percutaneous drainage of bile liver abscess. The experimental results confirmed that hepatic arterial embolization agent anhydrous ethanol can cause local liver necrosis and bile duct necrosis. Conclusion : The use of vascular sclerosing agents such as sodium morrhuate for non-superselective embolization of the hepatic artery will result in necrosis of the normal liver and biliary tract outside the lesion, and its treatment is very difficult. And call for asymptomatic hepatic hemangiomas should be strictly selected treatment indications.
