Fig 1. A, Thrombus formation at the origin (arrowhead) and distal total occlusion (arrow) of the right PCA in association with protrusion of a coil into the parent artery on near-completion angiography during coiling of a large basilar tip aneurysm. B, Angiogram 20-minutes post-intra-arterial abciximab demonstrates restored patency of the right PCA with a small residual amount of thrombus (arrowhead) at the aneurysm neck–parent artery interface. C, Angiogram 6 months after embolization demonstrates complete exclusion of the aneurysm and arterial patency with resolution of thrombus.
