Figure 1: PA view angiographic runs of brachiocephalic artery (a) and left VA (b) showing complete occlusion of the right subclavian artery at origin (red cross) and flow reversal in the right VA (represented by yellow arrows). Composite angiographic image (c) showing the level of brachiocephalic artery block (black arrow and red slab). Pictorial reconstruction of the distal subclavian artery and VA has been done depicting the blood flow, and arterial opacification had the occlusion not been present. 3D rotational angiography (d) showing VBJ aneurysm adjacent to right AICA origin
