Randomized Controlled Trial Multicenter Study Clinical Trial
Prognostic value and determinants of ultraearly angiographic vasospasm after aneurysmal subarachnoid hemorrhage.
A small number of patients with aneurysmal subarachnoid hemorrhage have angiographic evidence of cerebral vasospasm within 48 hours of the onset of hemorrhage. The present study analyzes the prognostic value and determinants of this ultraearly angiographic finding. ⋯ Our analysis suggests that patients with angiographic evidence of vasospasm at admission are at high risk for both symptomatic vasospasm and poor outcome. We also found that early surgery did not aggravate this risk.
