本文报告经支气管动脉注入抗癌药物(BAI)治疗肺癌的经验。适应证为支气管动脉造影时血流丰富者均有效,而支气管动脉分布较少,由肺动脉营养的肺泡上皮癌为禁忌证。操作:用带防止逆流的有适宜弯度的 Kifa(红色的)导管,从股动脉插入,导管上行前端至胸部大动脉内,在左主支气管的透亮区寻找支气管动脉的起始部,应注意导管前端不要抵向后壁而损伤脊髓。进入选择的动脉后,用约10ml 的造影剂作连续摄影,确认肿瘤及淋巴结转移灶的血流分布,需注意来自对侧支气管动脉、肋间动脉和内胸动脉等体循环营养血管的可能性。若有数条血管参于时,根据血管增生的程度 This article reports the experience of transbronchial arterial infusion of anticancer drugs (BAI) for the treatment of lung cancer. Indications for the bronchial arterial angiography are rich in blood flow are effective, while the distribution of bronchial artery is less, from the pulmonary artery of pulmonary alveolar epithelial cancer as a contraindication. Operation: Insert a catheter from the femoral artery with a suitably curved Kifa (red) tube with a reverse flow to prevent reflux. The catheter is advanced to the thoracic aorta. Find the beginning of the bronchial artery in the translucent region of the left main bronchus. Pay attention to the catheter tip. Do not reach the posterior wall and injure the spinal cord. After entering the selected artery, approximately 10 ml of contrast agent was used for continuous imaging to confirm the blood flow distribution of the tumor and lymph node metastasis. Attention should be paid to the possibility of circulatory nutrient vessels from the contralateral bronchial artery, intercostal artery, and internal thoracic artery. If there are several blood vessels involved, depending on the degree of vascular proliferation
