自从颅脑CT 摄影术在临床开展以后,缺血性脑血管疾病的诊断已基本解决,而本病的治疗虽有所改进和提高,却不甚理想。兹将近年来的进展综述于下:一、短暂性脑缺血发作的治疗短暂性脑缺血发作若不注意防治,其后往往发生脑梗塞或心肌梗塞,现多采用阿斯匹林。阿斯匹林通过抑制环氧化酶使血小板的花生四烯酸转化为血栓烷A_2的过程受阻而抑制血小板聚集和血管收缩。阿斯匹林又能抑制血管内膜细胞的花生四烯酸合成前列环素,而前列环素具有血管扩张作用和抗血小板聚集,但前者对阿斯匹林的作用较后者更为敏感,故现多主
Since the brain CT imaging in clinical practice, the diagnosis of ischemic cerebrovascular disease has been basically solved, while the treatment of this disease has improved and improved, but not ideal. The progress of recent years will be reviewed in the following: First, the treatment of transient ischemic attacks Transient ischemic attack if not pay attention to prevention and treatment, followed by cerebral infarction or myocardial infarction often occur, the use of aspirin. Aspirin inhibits platelet aggregation and vasoconstriction by inhibiting the conversion of platelet arachidonic acid to thromboxane A2 by cyclooxygenase. Aspirin can inhibit arachidonic acid synthesis of prostacyclin in the intima cells, while prostacyclin has vasodilator and anti-platelet aggregation, but the former is more sensitive to aspirin than the latter, So now multi-Lord
