在脑血管病死亡的病例中,蛛网膜下腔出血(SAH)可达总数的14%。对囊性动脉瘤及其继发破裂的原因了解不多,其说不一。晚近,一些作者在动物实验中发现,动脉瘤及动脉粥样硬化的形成,与病毒感染有关。Burch 等报导1例因心肌病而死亡的病人,其主动脉有脂质堆积,类似动脉粥样化;同时在主动脉中发现了柯萨奇病毒B_4抗体。新近的证据揭示SAH 可能与间发性病毒感染有直接关联。Jones 认为,流感病毒A 感染可能为动脉瘤的初发因素,甚至是动脉瘤破裂的一个病因。他查阅了25例SAH 病人的资料,发现20例有A 型流感病毒抗体滴 In the case of death from cerebrovascular disease, subarachnoid hemorrhage (SAH) up to 14% of the total. The reasons for cystic aneurysms and its secondary rupture are not well understood. Recently, some authors found in animal experiments that the formation of aneurysms and atherosclerosis is related to viral infection. Burch et al. Reported 1 patient died of cardiomyopathy, the accumulation of lipid in the aorta, similar to atherosclerosis; also found in the aorta coxsackie B4 antibody. Recent evidence reveals that SAH may be directly linked to the risk of contracting a virus. Jones believes that influenza A infection may be the primary cause of aneurysm, and even aneurysm rupture of a cause. He consulted the data of 25 cases of SAH patients, found that 20 cases of influenza A virus antibody droplets
