Does an early ischemic lesion on postoperative CT predict poor outcome in patients with aneurysmal subarachnoid hemorrhage?
A new hypodense lesion on the first postoperative day CT scan is a strong, independent predictor of poor clinical outcome at 3 months in survivors of aneurysmal subarachnoid hemorrhage.
Siironen et al. (2007) studied this question.
