The follow up computed tomography (CT) scan (B) showed the progression of the brain edema. The angiograms (C) show a slight decrease of the size of the AVM compared with the previous angiograms and the disappearance of the whole draining vein of the AVM to the TS at the arterial phase. But at the venous phase (D), the proximal part of the vein of the AVM to the TS and a normal drainage were shown, but the distal part of this vein (white arrow) was not shown and the blood staining of the AVM nidus.
