求翻译：动脉粥样硬化是一种全身性的血管疾病，发生在不同的器官便产生相应的疾病。如供应心脏的冠状动脉发生动脉粥样硬化就会得冠状动脉硬化性心脏病（冠心病）。脑动脉发生动脉粥样硬化主要在供应脑部的大、中动脉，最容易发生狭窄的部位在颈部颈总动脉分叉处、椎动脉进入颅腔处、以及基底动脉起始和分叉处。由于血管内膜的破溃、脂质沉积形成斑块，血液中的血小板、纤维蛋白沉积在斑块上面并发生机化，造成血管壁增厚、血管腔变窄，导致脑供血不足。如果病变进一步发展，血管腔严重狭窄甚至完全闭塞，或在狭窄的基础上由于血液粘稠度高（俗称血稠），在斑块上形成血栓堵塞血管，便可发生这根血管供血区的脑细胞缺血坏死。是什么意思？

Atherosclerosis is a systemic disease, occurs in diseases of different organ will produce the appropriate. Where the heart of the supply of coronary atherosclerosis of coronary heart disease (coronary heart disease). Cerebral artery atherosclerosis occurs mainly in the supply of the brain, arteries, most prone to the narrow part in the bifurcation of the carotid artery and vertebral artery of the neck into the cranial cavity, as well as at the start and Basilar Artery bifurcation. Due to the vascular intimal ruptured, lipid storage formation of plaque, Blood platelet and fibrin deposition in the plaque above the vitality, resulting in narrow vessel wall thickening and vascular cavity, causing cerebral ischemia. If further development of the disease, vascular cavity of serious stenosis or occlusion, or on the basis of the narrow due to the high blood viscosity (commonly known as blood heavy), on the plaque thrombosis blocked blood vessels, could occur this vein blood donor area of ischemic necrosis of brain cells.
