动脉粥样硬化的病理变化
根据病变的发展 经过
可以把它分为以下三个时期
分别是脂纹和脂斑期
纤维斑块期
以及粥样斑块期
粥样斑块期又称粥瘤
具体表现
脂纹和脂斑期
表现为内膜下脂质沉积
这时看到
血管内皮的脂斑针帽大
而脂纹宽约1-2mm
长短不一 呈黄色 不高
或略隆起于内膜表面
纤维斑块期
脂质沉积到内膜
多量纤维组织增生
而形成纤维帽
脂质被深埋于深层
这时看到血管上有隆起于
内膜表面的斑块
早期灰黄色
表面纤维结缔组织增多
纤维组织变性呈瓷白色
略带光泽 像蜡蒂样
粥样斑块期
纤维帽下的组织
沉积处发生坏死
形成黄糊糊的粥米样的物质
斑块处有溃破
斑块处有纤维结缔组织增生
和钙岩沉着
使得斑块硬化
形成动脉粥样硬化
继发病变或复合病变
第一 斑块内出血
第二 斑块破裂
粥瘤性的溃疡
临床上把纤维帽薄
深层坏死灶大的斑块
称为易损斑块
这种斑块更容易破裂
三 血栓形成
如果在冠状动脉粥样硬化
脑动脉粥样硬化基础上
血栓形成
可以造成心肌梗死和脑梗死
第四 钙化
凡是有病变的组织
总是有钙岩沉着
第五 动脉瘤形成
脑动脉瘤破裂
可引起脑出血
主动脉瘤破裂
可引起致命性的出血
