A Pre-embolization arteriogram. B Postembolization arteriogram obtained during second embolization following rebleed eight days later. The vasculature significantly increased in calibre following restoration of normovolemia, with the microcoils ‘undersized’ relative to the vessel. The previously occluded segment is reperfused, including the pseudoaneurysm (arrow) (A). Repeat coiling with larger coils is needed to achieved stasis and occlusion of this segment (B)
