在14例成人前脑半球观察了大脑中动脉（MCA）的穿支。注意到它们的脑内段起源于MCA主干及其终末和侧支（皮质）。它们终止于基底节和内囊的某些部位。详细观察这些节段的走行、方向、形态、直径及分支。所有血管按口径分类。提示腔隙性脑梗死的大小取决于闭塞的穿支血管的管径和分支范围。脑内血管段的直径范围为80至840 μ m，其终末分支的直径范围为80至780 μ m，侧支的直径范围为50至400 μ m。分枝区的平均尺寸为：41.6 × 106。15.5对于整个穿通动脉为37.9 × 10 - 3 mm。15.5脑内段为23 mm; 13毫米的终端分支; 8.9 ×。5.5较大侧支为2.6 × 2.5mm。1.4 mm表示最小的分支。
Perforating branches of the middle cerebral arteries (MCA) were examined on the forebrain hemispheres of fourteen human brains. It was noticed that their intracerebral segments arose from the MCA main trunk, and its terminal and collateral (cortical) branches. They terminated in certain parts of the basal ganglia and internal capsule. The course, direction, shape, diameters and branches of these segments were examined in detail. Classification of all the vessels was made according to caliber. It was concluded that the size of lacunar infarcts depends on the caliber and ramification zone extent of the occluded perforating vessels. Diameters of the intracerebral segments of vessels ranged from 80 to 840 .mu.m, of their terminal branches from 80 to 780 .mu.m, and of the collateral branches from 50 to 400 .mu.m. The average size of the ramification zone was: 41.6 .times. 15.5 mm for the entire perforating artery; 37.9 .times. 15.5 mm for the intracerebral segment; 23 .times. 13 mm for the terminal branches; 8.9 .times. 5.5 mm for larger collateral branches; and 2.6 .times. 1.4 mm for the smallest branches.
