缺血性卒中在年轻成人是不常见的,其病因不清楚,曾提示多种危险因素,其中有吸烟,偏头痛,乙醇中毒,动脉性高血压,心脏病,高脂血症,血液病或胶元性血管病及糖尿病。曾推测感染在缺血性卒中的发病机理中起某些作用,脑梗塞是由于细菌性心内膜炎和脑膜炎合并的脓毒性栓子,血栓形成或血管炎。上呼吸道感染和肺炎双球菌性感染,水痘一带状疱疹和柯萨奇A_9病毒感染也与少数脑梗塞病人有关。本文作者对34例45岁以下(平均32岁)急性脑梗塞的住院病人和68名22～64岁(平均34岁)正常
Ischemic stroke is uncommon in young adults and its etiology is unclear and has prompted a number of risk factors including smoking, migraine, alcoholism, arterial hypertension, heart disease, hyperlipidemia, hematopathy or Gelatinous vasculitis and diabetes. Infections have been postulated to play a role in the pathogenesis of ischemic stroke, which is due to septic emboli, thrombosis or vasculitis associated with bacterial endocarditis and meningitis. Upper respiratory tract infections and pneumococcal infections, varicella zoster and Coxsackie A_9 virus infections are also associated with a minority of patients with cerebral infarction. In this study, 34 inpatients with acute cerebral infarction under 45 years of age (mean 32 years) and 68 normal adults aged 22-64 (mean 34 years)
