N-butyl cyanoacrylate (NBCA) is an adhesive material, which has been used as an embolic agent in various vascular beds. Its role in the management of patients with acute massive hemoptysis has not been reported. In this article we report our experience with 12 such patients who underwent bronchial artery embolization using NBCA and compare the results with 36 procedures using polyvinyl alcohol (PVA) particles. As compared with PVA, NBCA embolizations appear more durable, leading to fewer rebleeds. There were 12 episodes of recurrent hemoptysis after 36 procedures using PVA (33%) with 8 being due to bleeding from a previously embolized vessel. Conversely, there were only 2 of the 12 patients who were treated by NBCA who experienced rebleed (16.6%). In this article, we describe the technical nuances of NBCA embolization of bronchial arteries and review potential pitfalls.
氰基丙烯酸正丁酯（NBCA）是一种粘合材料，已被用作各种血管床的栓塞剂。其在急性大量咯血患者治疗中的作用尚未见报道。在本文中，我们报告了12例使用NBCA进行支气管动脉栓塞的此类患者的经验，并将结果与36例使用聚乙烯醇（PVA）颗粒的手术结果进行比较。与PVA相比，NBCA栓塞似乎更持久，再出血更少。使用PVA的36例手术后有12次咯血复发（33%），其中8次是由于先前栓塞的血管出血。相反，接受NBCA治疗的12例患者中只有2例出现再出血（16.6%）。在本文中，我们描述了支气管动脉NBCA栓塞的技术细节并回顾了潜在的陷阱。
