(A) Frontal digital subtraction angiography (DSA) demonstrates cutoff of the superior division M2 branches (yellow arrow). (B) Lateral DSA demonstrates decreased flow of the right M3 branches feeding the parietal lobe (blue arrow) and distal M2 branches feeding the frontal lobe (yellow arrow). (C) Frontal DSA post-treatment demonstrates partially recanalized flow in the superior division, right M2 branch (yellow arrow) that feeds the posterior frontal and opercular frontal lobe. (D) Lateral DSA post-treatment demonstrates flow in superior M2 branch (yellow arrow) that feeds the posterior frontal and opercular frontal lobe. The parietal branch M3 occlusion persists (blue arrow).
