NBCA（N-butyle-2-cyanoacrylate）を用いた気管支動脈塞栓術

抄録

The liquid embolic material n-butyl-2-cyanoacrylate (NBCA) is widely used in various vascular interventional radiology procedures, and its use has recently been reported for bronchial artery embolization (BAE). NBCA in a mixture with lipiodol has the advantage of a low rate of post-embolic recanalization compared with that of other embolic materials such as metallic coils and gelatin sponge. Because the operator must adjust the concentration of NBCA-lipiodol to control the polymerization time, to avoid major complications it is important that procedures in which NBCA is used are performed by experienced interventional radiologists. Here we describe the technical aspects of BAE with NBCA, the safety of the procedure, potential pitfalls such as pathological change after BAE, our clinical experience, and experimental results.
