Figure 4: (a) Right vertebral angiogram having an 8 mm aneurysm in the proximal PICA segment with partial incorporation of the artery (b) Coiling was done in this with balloon placed in the vertebral artery as a good cage formation within the sac could be achieved. (c and d) Post coiling a small thrombus formation was observed in PICA (arrow in c) likely because of reduced fl ow in the PICA which rapidly progressed to complete occlusion of PICA (arrow in d). (e) Intrarterial infusion of abciximab was given through the microcatheter placed at PICA origin which partially canalized the PICA Abbreviation: PICA posterior inferior cerebellar artery Post coiling the PICA is patent due to stent and the aneurysm is fully occluded PICA: Posterior inferior cerebellar artery
