Abstract: Purpose: To analyse and evaluate the therapeutic effect of the double interventional therapy of bronchial artery chemotherapy and CT guided percutaneous absolute alcohol injection (PEI) in primary lung carcinoma. Meterials and Methods: 20 cases with primary lung carcinoma were treated by single bronchial artery chemotherapy, the total times were 68; 20 cases were treated by single chemoembolism, the total times were 22; 40 cases were all treated by double interventional therapy in the same time of chemotherapy, 20 cases were treated by bronchial artery embolism, the total operations were 28 times, and the local chemotherapy was 40 times. Single chemotherapy were 20 cases, it was total 64 times. During the period of treatment, CT guided percutaneous absolute alcohol injection therapy was done on the 40 patients, it was total 118 times. ResultS: The clinic effective rates of bronchial artery chemoembolism and single chemotherapy were 70% and 30%. The clinic effective rate of double intervention therapy is 90% and 80% individually. No adverse reaction and severe complications occurred. Conclusion: Double interventional therapy has much higher clinic effective rates and survival rate than single bronchial artery chemotherapy or chemo embolism. It has notable difference (P＜0.01).
