High grade left proximal subclavian artery stenosis with signal loss of the left VA on time-of-flight images due to flow reversal.
Case Discussion
The normal antegrade flow signal of the left VA is missing in the 3D TOF images. On time-resolved 3D CE-MRA, the vessel shows delayed, retrograde contrast filling.
