大脑动静脉畸形(AVM)是以许多大的异常血管通道伴有内皮和弹力层发育不全为特征的病变,其血管腔内压低,流速快,容易导致血液不规则流动和湍流.这种血液湍流可造成血管内皮损伤,血小板粘附在暴露的内皮下胶原上,继而促发凝血?烷和前列腺素的合成及血小板脱粒,逐进一步导致血小板聚集,加上从活化的血凝块中产生的纤维素可 Cerebral arteriovenous malformations (AVMs) are lesions characterized by many large, abnormal vascular passages with hypoplastic endothelium and elastosis, with low intravascular lumen velocity and fast flow rates that can easily lead to irregular blood flow and turbulence in the bloodstream. Can cause vascular endothelial damage, platelets adhere to the exposed subendothelial collagen, which in turn triggers the synthesis of thromboxane and prostaglandins and thrombocytopenia, further leading to platelet aggregation, together with the fibers produced from activated blood clots Vegetarian
