Despite recent advances in diagnostic and therapeutic techniques, subarachnoid hemorrhage (SAH) isstill a serious condition associated with high mortality and morbidity. There are no effective treatmentsother than surgical intervention. However, another option for decreasing the occurrence of SAH may beprevention of aneurysms formation and of their rupture by controlling risk factors. Cigarette smoking hasbeen recently shown to be one of the major risk factors for SAH.

We investigated whether cigarette smoking increased the risk of developing cerebral aneurysms and ofSAH. Degree of smoking was investigated in 182 patients with SAH and in 123 patients with an unrup-tured cerebral aneurysm incidentally detected (luring investigation of other diseases. Sixty-nine patientswith other diseases who were shown to be free of cerebral aneurysms through MR angiography served ascontrols. Smoking significantly increased the risk of both aneurysm formation and SAFI : The odds ratiofor SAH was 2.4, and for unruptured cerebral aneurysm 1.7. Smoking especially increased the occurrenceof SAH in women and in youngsters. However, smoking did not influence the occurrence of cerebral vaso-spasm and multiplicity of aneurysms. These data suggest the importance of avoiding smoking to preventthe occurrence of cerebral aneurysms and of SAH.
