Rheological Behavior of Platelets in Situ in Middle Cerebral Artery Occlusion

摘要: The observation of platelet microemboli in the retinal artery a patient with amaurosis fugax by Fisher [4] led to serious consideration role platelets transient ischemic attacks and also cerebrovascular diseases many investigators clinicians this field. Thus, functions patients have been subject much study discussion recent years [1]. Increased aggregability adhesiveness demonstrated stroke [6, 10, 13, 14]. Most these studies, however, were performed an vitro aggregation technique which has criticized as having limitations test for measurement vivo activity [2]. On other hand, it suggested that cerebral ischemia itself stimulates formation aggregates, could contribute process [3]. Thus pathogenesis occlusive may two stages: one cause thrombotic or embolic occlusion vessel, factor disturbance microcirculation after artery.
