大咯血行支气管动脉栓塞的栓塞材料研究进展

支气管动脉栓塞术（BAE）是将栓塞材料定向注入支气管动脉，封闭责任血管，达到迅速止血的效果，现已成为针对大咯血内科保守治疗无效时的首选治疗手段，目前临床上所使用的栓塞材料种类繁多，可以适应不同的部位、不同的病因、不同的病变基础，种类包括机械栓塞材料弹簧圈、液体栓塞材料氰基丙烯酸正丁酯（NBCA）、广泛应用的明胶海绵（GSA）和聚乙烯醇（PVA）颗粒以及逐渐推广的各型微球。该文旨在对栓塞材料的种类、特性、应用范围以及各自的优缺点做一综述。

Advance in embolic materials for bronchial artery embolization with massive hemoptysis

Bronchial artery embolization (BAE) is to inject the embolized material into the bronchial artery directionally and embolize the responsible vessel to achieve the effect of rapid hemostasis. It has become the preferred treatment for patients with severe hemoptysis who fail to receive conservative treatment. Currently, there are many kinds of embolization materials used in clinic, which can be adapted to different sites, different etiologies and different pathological bases including mechanical embolization material spring coil, liquid embolization material N-Butyl-2-Cyanoacrylate (NBCA) , widely used gelatine sponge (GSA) and polyvinyl alcohol (PVA) particles and gradually popularized microspheres. This article aims to review the types, characteristics, application scope and disadvantages of embolization materials.
