随着纤维外科、神经介入放射学在临床上的应用,闭塞性脑血管病的治疗方法逐渐增多。主要目的:尽早解除阻塞,供给脑组织有效循环血量,保证脑功能,改善病人的预后。 1 颈总、颈内动脉不全闭塞的外科和激光治疗 引起颈段血管狭窄的最主要原因是动脉粥样硬化斑块的形成,其病变多开始于颈总动脉的远端,并向颈内及颈外动脉延伸到不同程度。脂质沉积并变性,局限于血管内膜的内皮细胞下层及肌层的内弹力层。当血管内病变达到一定程度时,血流明显受阻而产生缺血症状性病变。其临床主要表现为短暂性脑缺血的发作,一过性黑朦,重者致缺血性卒中。一般观点,短暂性脑缺血发作,若不给予治疗,卒中发生率为每年4％～10％。
With the clinical application of fiberoptic and nerve interventional radiology, the treatment of occlusive cerebrovascular disease is gradually increasing. The main purpose: to unblock as soon as possible, to provide effective circulation of brain blood volume to ensure brain function and improve patient prognosis. 1 neck, total carotid artery occlusion of the surgical and laser treatment of cervical stenosis caused by the most important reason is the formation of atherosclerotic plaque, the lesions began in the distal common carotid artery, and to the neck and External carotid artery extends to varying degrees. Lipid deposition and denaturation, confined to the endothelium of the intima of the blood vessel and the inner elastic layer of the muscular layer. When the intravascular lesions to a certain extent, the blood flow was significantly blocked and produce ischemic lesions. The main clinical manifestations of transient ischemic attack, transient darkness, severe ischemic stroke. The general point of view, transient ischemic attack, if not given treatment, the incidence of stroke was 4% to 10% per year.
