Although n-butyl-2-cyanoacrylate (NBCA) has been used as an effective liquid embolization material, its indication for pseudoaneurysms has seemingly been limited because of the technical difficulties of using NBCA, such as reflux to the parent artery and causing significant infarction. Thus, considerable skill in using NBCA or a device to control blood flow during its polymerization is required to achieve embolization without severe complications. We report our new technique for controlling blood flow using diluted epinephrine in transcatheter arterial NBCA embolization of five pseudoaneurysms in four cases secondary to hemosuccus pancreaticus.
虽然正丁基-2-氰基丙烯酸酯（NBCA）已被用作一种有效的液体栓塞材料，但由于使用 NBCA 存在技术困难，如回流至母动脉并导致明显梗死，其假性动脉瘤的适应证似乎受到限制。因此，在聚合过程中使用 NBCA 或控制血流的设备需要相当高的技巧，以实现无严重并发症的栓塞。我们报告了在四例因胰血吸瘤导致的五个假性动脉瘤的经导管动脉 NBCA 栓塞中使用稀释肾上腺素控制血流的新技术。
