吸烟与动脉瘤性蛛网膜下腔出血(SAH)有关,并可继发血管痉挛。作者分析了1987～1994年间北美、欧州动脉瘤性SAH患者3441例,欧州为1组,病例数为1023人,北美随机分为4组,每组人数分别为906人,365人,245人,902人。患者年龄至少18岁,均经脑血管造影证实为囊性动脉瘤致SAH。5组分为近期吸烟者,曾吸烟者和不吸烟者。近期吸烟者是发生SAH时仍在吸烟者,以前吸烟者是有吸烟史,但SAH时未吸烟者,不吸烟者是从未吸过烟者。每组吸烟者大约1/3为男性,女性年龄大于男性动脉瘤出血近期与曾吸烟、不吸烟的平均年龄有显著差异(4组中P<0.0001第5组中P<0.0005)。5组中治疗方法随机选
Smoking is associated with aneurysmal subarachnoid hemorrhage (SAH) and may be secondary to vasospasm. The authors analyzed 3441 cases of aneurysmal SAH in North America and Europe during 1987-1994 and 1 case in Europe, with a total of 1023 cases. The North American population was randomly divided into 4 groups with 906, 365 and 245 respectively. 902 people. Patients aged at least 18 years of age, were confirmed by cerebral angiography as cystic aneurysm-induced SAH. 5 groups are recent smokers, former smokers and non-smokers. Recent smokers are still smokers in the presence of SAH, formerly smokers have a history of smoking, but not smokers at SAH, non-smokers who have never smoked. Approximately one-third of smokers in each group were men, and older women than men had bleeding with aneurysms. There was a significant difference between the mean age of smokers and non-smokers (p <0.0001 for group P <0.0005 for group 5). 5 groups were randomly selected treatment
