a-c Variation of DBT with unexpected flow redistribution. a An angiogram from the left hepatic artery demonstrated contributing vessels to target lesion in segment 4 with adjacent origin of the segment 3 arteries (black arrow head). b A Sniper microcatheter was placed in to the segment 3 arteries and balloon inflated to protect segment 3 parenchyma (green arrow), and a second microcatheter placed proximal to direct flow into feeding branches (red arrow). However, flow to segment 2 was identified (white arrows). c Interestingly, when the proximal balloon was deflated, less flow was noted to segment 2, so this area was treated with only distal occlusion
