目的观察膈下动脉形成肝癌侧枝血供的因素和几率。方法在对137例患者介入治疗中,造影寻找膈下动脉,并超选形成肿瘤血供的膈下动脉,进行化疗栓塞。结果137例患者中有21例经膈下动脉介入治疗(占15.3%),其中原发性肝癌手术切除后复发2例(9.5%),首次介入治疗出现膈下动脉供血3例(14.3%),2次或多次介入治疗后出现膈下动脉供血16例(76.2%)。结论膈下动脉是原发性肝癌的最重要侧枝供血动脉,经膈下动脉介入化疗栓塞原发性肝癌成功率高而且并发症少。
Objective To observe the factors and probability of subcutaneous hypoglossal artery for the production of hepatic cancer collateral blood supply. Methods 137 patients undergoing interventional therapy, angiography to find the subphrenic artery, and ultra-select the formation of tumor blood supply to the subphrenic artery for chemoembolization. Results Of the 137 patients, 21 (15.3%) were treated with subphrenic arterial intervention, of which 2 (9.5%) were recurrent after primary hepatic cancer resection and 3 (14.3%) had subcutaneous arterial blood supply during the first interventional therapy. In 2 or more interventional treatment, there were 16 cases (76.2%) of subphrenic artery blood supply. CONCLUSIONS: The subphrenic artery is the most important collateral supplying artery for primary liver cancer. The success rate of primary hepatic carcinoma embolization by subphrenic arterial chemoembolization is high and there are few complications.
