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 microns, of their terminal branches from 80 to 780 microns, and of the collateral branches from 50 to 400 microns. The average size of the ramification zone was: 41.6 X 15.5 mm for the entire perforating artery; 37.9 X 15.5 mm for the intracerebral segment; 23 X 13 mm for the terminal branches; 8.9 X 5.5 mm for larger collateral branches; and 2.6 X 1.4 mm for the smallest branches.
在14个大脑的前脑半球上检查了大脑中动脉(MCA)的穿支。注意到它们的脑内段起源于MCA主干及其终末支和侧支(皮质支)。它们终止于基底神经节和内囊的某些部位。详细检查了这些段的走行、方向、形状、直径和分支。根据管径对所有血管进行了分类。得出的结论是,腔隙性梗死的大小取决于闭塞穿支血管的管径和分支区域范围。血管脑内段的直径范围为80至840微米,终末支为80至780微米,侧支为50至400微米。分支区域的平均大小为:整个穿支动脉为41.6×15.5毫米;脑内段为37.9×15.5毫米;终末支为23×13毫米;较大侧支为8.9×5.5毫米;最小分支为2.6×1.4毫米。
