目的 :分析肝癌侧支循环的DSA表现。方法 :对 35例肝癌患者进行选择性腹腔动脉或肝动脉造影 ,其中 5例单纯行肝动脉灌注化疗 ,30例以碘油抗癌乳剂及明胶海绵进行栓塞。结果 :①肝内侧支 15例 ,其中叶内侧支 10例 ,叶间侧支 5例。②肝外侧支 2 4例 ,其中膈下动脉 7例 ,肠系膜上动脉 4例 ,胰十二指肠动脉弓 3例 ,胃左动脉 3例 ,肝固有动脉 3例 ,胃十二指肠动脉 2例 ,胃网膜右动脉及右肾动脉各 1例。结论 :①侧支循环形成是导致肿瘤复发的重要因素 ,为进一步栓塞治疗带来困难。②栓塞侧支循环有助于提高疗效
Objective: To analyze DSA manifestations of collateral circulation of liver cancer. Methods: Selective celiac or hepatic arteriography was performed in 35 patients with liver cancer. Among them, 5 patients underwent hepatic arterial infusion chemotherapy alone and 30 patients were treated with lipiodol emulsion and gelatin sponge. Results: ① There were 15 cases of intrahepatic branches, including 10 cases of medial branch and 5 cases of interlobar branch. ② extrahepatic lateral branches in 24 cases, including 7 cases of subphrenic artery, superior mesenteric artery in 4 cases, 3 cases of pancreaticoduodenal artery bowel, 3 cases of left gastric artery, 3 cases of hepatic artery, gastroduodenal artery 2 Cases, right gastric artery and right renal artery in 1 case. Conclusion: The formation of collateral circulation is an important factor leading to tumor recurrence, which brings difficulties for further embolization. ② embolization collateral circulation helps to improve the curative effect
