Embolization of the aneurysm. (a) Two microcatheters are placed in the aneurysm and pulmonary artery proximal to the aneurysm. One microcatheter is used for proximal segmental pulmonary artery coil blocking proximal to the aneurysm (arrow); the other microcatheter is positioned into the aneurysm (arrowhead) before injecting a mixture of NBCA and iodized oil. (b) Complete filling of the aneurysm with the mixture of NBCA and iodized oil (arrow) is performed using the other microcatheter. NBCA, n-butyl-2-cyanoacrylate.
