Queston #9084Note

The polar (tuberothalamic) artery supplies the anterior pole of the thalamus (anterior nuclei and a portion of the anterior region of the dorsomedial nucleus) and is the only thalamic artery to branch off of the PCOM, and therefore the only that can be involved in an anterior circulation stroke. The remaining blood supply to the thalamus is posterior circulation via branches off of the PCA.
