Bronchial arterial infusion(BAI)and bronchial arterial chemoembolization(B ACE)have been used in the clinical treatment of lung cancer since the 1980s.As BAI/BACE carries a better objective response rate and lower adverse effect rate than systemic chemotherapy,its clinical application has attracted much attention,although BAI/BACE has not been included in the guidelines and norms related to lung cancer treatment so far because there is a lack of high-level evidence-based medical evidence.On this account,through conducting a systematic review of domestic and foreign research literature,extensively collecting opinions and suggestions from domestic peer experts,combining clinical practice experience,and making comprehensive and in-depth discussion,this consensus has reached a basic agreement on the following aspects of BAI/BACE treatment for lung cancer:theoretical basis(especially the research results of lung cancer blood supply),indications,contraindications,preoperative evaluation items,preoperative preparation,operating procedures,efficacy evaluation,comprehensive treatment,prevention and treatment of complications,and follow-up requirements,etc.This consensus provides a reference basis and technical support for the clinical practice and research of BAI/BACE.It is expected that BAI/BACE will play a better role in the clinical comprehensive treatment of lung cancer.(J Intervent Radiol,2024,33:219-229)
