应用半连续切片法对48例58个冠状动脉血栓进行了分析,结果表明,冠状动脉不同分支和部位的血栓形成所引起的后果不尽相同。左主干血栓均为新鲜血栓,体积小,很快引起病人死亡;右主干血栓体积大,往往是机化血栓和新鲜血栓并存。血栓系发生在冠状动脉硬化斑块引起严重狭窄的部位,且均为“进展性”斑块。有些病例仅有血栓而没有心肌梗塞的形态学证据,因此作者认为在多数情况下冠状动脉血栓形成是心肌梗塞的原因而不是结果。
48 cases of 58 coronary artery thrombosis were analyzed by semi-continuous biopsy. The results showed that the effects of thrombosis in different branches and locations of coronary artery were different. Left main thrombus are fresh thrombus, small size, and soon cause the patient to die; right main thrombus volume, often organic thrombus and fresh thrombus co-exist. Thrombosis occurred in severe coronary atherosclerosis plaque site, and are “progressive” plaque. In some cases, there is only thrombus without morphological evidence of myocardial infarction, so the authors believe that in most cases coronary thrombosis is the cause of myocardial infarction and not the result.
