    Notes: Summary Retrograde filling of seven anterior choroidal arteries from the posterior circulation was observed on a vertebral angiogram in six patients with occlusion of the proximal anterior choroidal artery or of the internal carotid artery. In one patient with thrombotic occlusion of the internal carotid artery, the enlarged anterior choroidal artery functioned as a major collateral pathway from the posterior circulation to the territory of the middle cerebral artery. Retrograde filling of the anterior choroidal artery is a sign of obstruction changes in the ipsilateral carotid artery at or proximal to the origin of the anterior choroidal artery.

    Notes: Abstract The distribution of the anterior choroidal artery (AChA) was analysed on coronal, sagittal and axial microangiograms of cadaver brains. On axial sections, the territory of the AChA was confirned to an arcuate zone between the striatum anterolaterally and the thalamus posteromedially. On sagittal sections, fine vessels from the cisternal part of the AChA were seen to extend upwards and somewhat posteriorly into the region of the posterior limb of the internal capsule. On coronal sections, ascending branches of the AChA coursed latcrally and then upwards to penetrate the globus pallidus and the inferior portion of the posterior limb of the internal capsule, apparently terminating at the lateral border of the thalamus. Determining the distribution of this artery on multiplanar sections was helpful for interpreting pathological changes, including infarcts, occurring in this region on multiplanar CT and/or MR images.
