The anterior perforating arteries, the group of arteries that enter the brain through the anterior perforated substance (APS), were examined using X 3 to X 40 magnification in 50 cerebral hemispheres obtained from 25 adult cadavers. These arteries arose from the internal carotid, middle and anterior cerebral, and the anterior choroidal arteries. The carotid branches to the APS arose distal to the origin of the anterior choroidal artery. The anterior choroidal artery branches arose from the main or superior branch of the artery. The middle cerebral artery branches to the APS (the lenticulostriate arteries) arose from the M1 and M2 segments and were divided into medial, intermediate, and lateral groups, each of which had a characteristic configuration. The anterior cerebral artery branches arose from the A1 segment and from the recurrent artery. The internal carotid and anterior choroidal artery branches entered the posterior half of the central portion of the APS. The lenticulostriate branches entered the middle and posterior portions of the lateral half of the APS. The A1 segment gave rise to branches which entered the medial half of the APS above the optic nerve and chiasm. The recurrent artery sent branches into the anterior two-thirds of the full mediolateral extent of the APS. The relationship of these branches to the cerebral structures above the APS and to the common aneurysm sites is reviewed.
经前穿质（APS）进入脑内的前穿动脉组，在取自25具成年尸体的50个大脑半球中，使用3倍至40倍放大倍数进行了检查。这些动脉起源于颈内动脉、大脑中动脉、大脑前动脉和脉络膜前动脉。颈内动脉至APS的分支起源于脉络膜前动脉起始部的远心端。脉络膜前动脉分支起源于该动脉的主干或上支。大脑中动脉至APS的分支（豆纹动脉）起源于M1和M2段，分为内侧、中间和外侧组，每组都有其特征性形态。大脑前动脉分支起源于A1段和返动脉。颈内动脉和脉络膜前动脉分支进入APS中央部分的后半部。豆纹动脉分支进入APS外侧半的中部和后部。A1段发出的分支进入视神经和视交叉上方APS的内侧半。返动脉发出的分支进入APS整个内外侧范围的前三分之二。本文回顾了这些分支与APS上方脑结构以及常见动脉瘤部位的关系。
