Asymptomatic DCI signals higher poor-outcome risk in SAH; this Level-3 cohort finding leaves open whether intensified screening changes management.
Does asymptomatic delayed cerebral ischemia compared to symptomatic DCI worsen outcomes in patients with subarachnoid hemorrhage?
Asymptomatic delayed cerebral ischemia is common in comatose patients after subarachnoid hemorrhage and is associated with a significantly higher risk of death or moderate-to-severe disability compared to symptomatic DCI.
Schmidt et al. (2008) studied this question.
