Key result
Pre-operative atrial fibrillation (prevalence 3.7% in elective vs 7.2% in emergency procedures; p=0.0012) was associated with increased risk of poor 6-month neurological outcome in emergency cases.

Does pre-operative atrial fibrillation worsen survival and neurological outcomes in patients undergoing intracranial neurosurgical procedures?
Pre-operative atrial fibrillation is associated with worse neurological outcomes in patients undergoing emergency, but not elective, intracranial neurosurgical procedures.
Bilotta et al. (2009) conducted a cohort in Intracranial neurosurgical procedures (n=2,020). Pre-operative atrial fibrillation vs. Sinus rhythm was evaluated on 6-month neurological outcome and survival. Pre-operative atrial fibrillation (prevalence 3.7% in elective vs 7.2% in emergency procedures; p=0.0012) was associated with increased risk of poor 6-month neurological outcome in emergency cases.
