血管狭窄的原因有哪些 毛伟 徐州矿务集团总医院
脑血管狭窄的原因主要有以下几个方面：第一个，是动脉粥样硬化。动脉粥样硬化的主要原因是高血压、糖尿病，还有年龄增长，这是脑血管狭窄最常见、最主要的因素；第二个，是血管的炎症，血管的炎症造成血管内膜的发炎，引起血管的狭窄；第三个，是血管的夹层，血管的夹层因为血管内膜翘起来以后，血液的冲击造成管腔的狭窄。还有其他的一些原因，包括放射性的损伤，如放疗以后放射性治疗，肿瘤患者进行放射性治疗以后的损伤而造成的狭窄，另外，血管壁痉挛也是重要原因，还有压迫，血管外的压迫造成血管的狭窄等。随着年龄的增加，男性55岁以后、女性65岁以后动脉血管将逐渐老化出现斑块，表面变得凹凸不平，继而导致血管狭窄。如同用久的水管生锈一样，是自然过程，谁都要经历，但有的人出现早，有的人出现晚。换句话说动脉斑块出现的过程不可逆转，但进展速度可以延缓。

What are the causes of vascular stenosis
The main causes of cerebrovascular stenosis are as follows: first, It's atherosclerosis. The main causes of atherosclerosis are hypertension and diabetes, And age, This is the most common and main factor of cerebrovascular stenosis; the second, It's inflammation of blood vessels, Inflammation of blood vessels causes inflammation of the intima, Cause stenosis of blood vessels; Third, It's a vascular dissection, The dissection of blood vessels is caused by the warping of the intima, The shock of blood causes the lumen to narrow. There are other reasons, Including radiation damage, For example, radiation therapy after radiotherapy, The stricture caused by the injury of tumor patients after radiotherapy, In addition, Vasospasm is also an important cause, And oppression, The compression outside the blood vessel causes the stenosis of the blood vessel and so on. With the increase of age, After the age of 55 in men and 65 in women, the artery will gradually age and appear plaque, The surface becomes uneven, This leads to vascular stenosis. As rusty as a long pipe, It's a natural process, Everyone has to go through it, But some people appear early, Some people show up late. In other words, the process of arterial plaque is irreversible, But progress can be delayed.
