Abstract

BACKGROUND: Aneurysmal subarachnoid hemorrhage is a rupture leading to blood accumulating in the subarachnoid region. Smoking status is often a risk factor for postoperative complications for vascular procedures. This study aims to retrospectively examine the effect of being a current tobacco smoker on postoperative outcomes in patients with nontraumatic subarachnoid hemorrhage. METHODS: Patients with aneurysmal subarachnoid hemorrhage who underwent craniotomy were identified in the American College of Surgeons-National Surgical Quality Improvement Program database. The 30-day perioperative outcomes of current smokers were compared with those of control individuals, who were patients who had not smoked tobacco in the past year. Postoperative outcomes included death, cardiac complications, stroke, operation time >4 hours, bleeding, and other events. In addition, this study examined the same surgical outcomes in patients older than 65 years. RESULTS: We found no significant difference between these 2 groups across all adverse outcomes analyzed. In patients aged >65 years, we again found no significant differences between these 2 groups across all adverse outcomes analyzed. CONCLUSIONS: This study shows that although current tobacco smoker status is commonly a risk factor for vascular diseases and postoperative complications, it is not a risk factor for the postoperative variables that we analyzed during craniotomy for aneurysmal subarachnoid hemorrhage. Additional research should be conducted to determine if different procedures to treat aneurysmal subarachnoid hemorrhage may have different outcomes among smokers.
