目的:探讨原发性肝癌化疗栓塞术后肿瘤的侧枝供血。材料与方法:连续观察200例经病理证实的原发性肝癌患者,常规行经导管动脉化疗栓塞术,重复治疗中,根据影像学资料进行相关动脉造影,对造影结果进行分析。结果:200例中有21例出现侧枝循环供血于肿瘤,其中14例来自肝外,分别是右膈下动脉3例,左右共干的膈下动脉2例,左膈下动脉1例,胃左动脉3例,胃十二指肠动脉2例,右侧内乳动脉2例,胆囊动脉1例;7例来自肝内,其中肝左动脉供应肝右页病灶4例,肝右动脉供应肝左叶病灶3例。总共17例出现在第三次治疗及以后。结论:肝癌经导管化疗栓塞术后肿瘤侧枝供血存在于部分患者,这一现象在临床工作中应得到重视。
Objective: To investigate the collateral blood supply of tumor after chemoembolization of primary liver cancer. MATERIALS AND METHODS: Two hundred patients with pathologically confirmed primary hepatocellular carcinoma (HCC) were enrolled in this study. Conventional transcatheter arterial chemoembolization (PTCA) and repeated therapy were performed. Angiography was performed on the basis of imaging data and the angiographic findings were analyzed. RESULTS: Twenty-one of the 200 patients had collateral circulation blood supply to the tumor, of which 14 were extrahepatic, including 3 cases of the right subphrenic artery, 2 cases of left and right subphrenic artery, 1 case of left subphrenic artery, 3 cases of artery, 2 cases of gastroduodenal artery, 2 cases of right internal mammary artery and 1 case of gallbladder artery. 7 cases came from the liver, in which the left hepatic artery supplied the right hepatic lesion in 4 cases and the right hepatic artery supplied the left hepatic artery Leaf lesions in 3 cases. A total of 17 cases occurred after the third treatment and beyond. Conclusions: Tumor blood supply to the collateral vessels in patients with hepatocellular carcinoma after transcatheter chemoembolization exists in some patients. This phenomenon should be emphasized in clinical practice.
