GSN and Intraventricular hemorrhage: Table 2 shows that there was a significantly higher likelihood of poor neurologic outcome at 6 months in patients that have higher WFNS score, Fisher score, glucose, C-reactive protein, fibrinogen and D-dimer concentration, and lower gelsolin level, and that more frequently showed intraventricular hemorrhage, external ventricular drain, vasospasm, and CT ischemia.
