本文用光镜、电镜观察了正常和硬化大脑中动脉及其豆纹支管壁弹性结构的形态。结果显示，硬化大脑中动脉内弹力膜断裂，且以外层断裂明显，波纹状外观消失；而豆纹支内弹力膜结构完整，波纹状外观清晰可见。平滑肌萎缩、变性，胶原纤维增多。提示硬化大脑中动脉破裂出血是内弹力膜破坏，平滑肌萎缩，管壁脆性增加所致；而豆纹动脉是根部存在＂中膜缺损＂，此外受血流冲击引起破裂的可能性大。
In this paper, the morphology of the elastic structures of normal and sclerosis middle cerebral arteries and their branches of legumes were observed by light microscope and electron microscope. The results showed that the elastic membrane in the sclera of the sclera of middle cerebral artery was broken, and the outer rupture was obvious and the appearance of wavy appearance disappeared. However, the structure of the inner elastic membrane of legume was intact and the appearance of wavy appearance was clearly visible. Smooth muscle atrophy, degeneration, increased collagen fibers. Prompt sclerosis of the middle cerebral artery hemorrhage is the destruction of the endometrial membrane, atrophy of the smooth muscle, the increase of the fragility of the tube; while the bean-shaped artery is the root of the “membrane defect”, in addition to the possibility of rupture by the impact of blood flow is large.
