摘要
对我院１９７８年８月至１９９３年７月收治的３０例６０岁以上蛛网膜下腔出血患者进行病因及临床表现分析，结果表明：老年人蛛网膜下腔出血的病因常见于高血压病和脑动脉硬化症。分别占４０％及５３．３％，而两者同时并存时发生率则更高，７６％多有高血压脑动脉硬化病史。临床表现：可无头痛和恶心，呕吐，即使出现也多在起病数分钟或数小时内或在病程中才逐渐出现，其程度多较轻。５０％病初无脑膜刺激征，而多在２４小时至４８小时或数日后逐渐出现，３０％于起病至病愈始终未发现此征。本组４０％出现不同程度的意识障碍，年龄越大，出现意识障碍的程度越高，局灶性的神经系统损伤症状较为常见。
Hpertension and cerebral arteriosclerosis are the common causes of Subarachnoid hemorrhage (SAH)in the aged. The meninges-stimulated signs are usually considered to be the characteristic of subarachnoid hernorrhage.In the present study,30 causes of subarachnoid hemorrhage in the agd(over 60 years)were analyzed. It was found that nearly half of the cases were lack of apparent meninges-stimulated signs. It is suggested that the comprehensive analysis of clinical history and other physical signs,as well as meninges stimulated signs, play an important role in the correct diagnosis of subarachnoid hemorrhage in the elderly.
