Prognostic value of the 2010 consensus definition of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage

Background and purposeDelayed cerebral ischemia (DCI) complicates the recovery of approximately 30% patients with aneurysmal subarachnoid hemorrhage (aSAH). The definition DCI widely varies, even though a consensus has been recommended since 2010. This study aimed to evaluate prognostic value 2010 in cohort aSAH.MethodsWe conducted single-center, retrospective, observational that included consecutive adult aSAH who were admitted intensive care unit from January December 2014. was evaluated 48 h 14 days after onset symptoms using criteria outcome assessed by Glasgow Outcome Scale (GOS) at discharge hospital.ResultsA total 340 analyzed incidence 37.1%. median time primary occurrence 97 h. Neurological deterioration observed most (89.7%) fulfilled criteria. strongly associated an unfavorable (GOS 1–3) hospital (OR 2.65, 95% CI 1.69–4.22, p < 0.001).ConclusionsThe is high its neurological outcome. finding adds previous literature, which shown appears be major contributor affecting functional ability survivors aSAH. To further advance reliable knowledge DCI, future studies should adhere DCI.
