目的：了解肝癌侧支循环的形成及其对碘油沉积形态的影响。方法：对６７例肝癌进行选择性血管造影，碘化油抗癌药乳剂及明胶海绵栓塞，栓后复查Ｘ线平片，增强ＣＴ，了解侧支循环的形成情况及碘油形态变化，并评价疗效。结果：有复发表现的２６例中，２１例存在侧支循环，其中１４例发生于载瘤肝动脉完全阻塞后，其供血区域碘油沉积缺损或稀少，并逐渐排空，为肿瘤存活区。结论：侧支循环供血是肝癌内碘油沉积少，复发较早的重要因素；形成侧支循环与碘油用量无关，与肝血流阻断情况有关；栓塞侧支循环可明显提高疗效。
Objective: To understand the formation of collateral circulation in liver cancer and its effect on lipiodol deposition. METHODS: Selective angiography was performed on 67 cases of liver cancer, iodized oil anticancer drug emulsion and gelatin sponge embolization, X-ray plain film was taken after suppository, and CT was enhanced to understand the formation of collateral circulation and changes in lipiodol morphology. Efficacy. RESULTS: Of the 26 cases with recurrent manifestations, 21 had collateral circulation, and 14 of them occurred after the hepatic artery was completely obstructed. The lipiodol deposition in the blood supply area was deficient or sparse, and it gradually evacuated. Conclusion: Collateral circulation is an important factor in the early deposition of less lipiodol deposition in liver cancer. The formation of collateral circulation has nothing to do with the amount of lipiodol, and it is related to the status of hepatic blood flow blockage. The embolization of collateral circulation can significantly improve the curative effect.
