肝癌患者作肝动脉药物灌注加栓塞治疗引发胆囊炎并发症者并非少见，对它的机理研究发现胆囊血供受阻是其主要原因。动物实验与电子显微镜观察显示在治疗早期药物与栓塞物可引起血管平滑肌的退变、坏死，以及小动脉壁内皮细胞脱落与血管阻塞等病理改变。
It is not uncommon for hepatocellular carcinoma patients to undergo hepatic arterial perfusion and embolization to induce complications of cholecystitis. A study of its mechanism revealed that the main cause of obstruction of blood supply to the gallbladder. Animal experiments and electron microscopy showed that early treatment of drugs and embolism can cause vascular smooth muscle degeneration, necrosis, and arteriole endothelial cell shedding and vascular obstruction and other pathological changes.
