Abstract
OBJECTIVE: To retrospectively analyze the relationship between fibrinogen levels and outcomes in poor-grade aneurysmal subarachnoid hemorrhage (aSAH). METHODS: We recruited 66 patients with poor-grade aSAH who were treated by neurosurgical clipping between January 2010 and December 2015. Serum samples were taken immediately on admission. Baseline information, complications, and outcomes at 6 months were recorded. Univariate and multivariate logistic regression analyses were used to explore the relationship between fibrinogen levels and clinical outcomes. RESULTS: Nineteen men and 47 women were included; the average age was 57.2 years. The median of the admission serum fibrinogen level was 3.3 g/L. Of the 66 patients, 18 had died by 6 months after initial hemorrhage, whereas 48 patients survived. Multivariate analyses showed that Hunt and Hess grade V (odds ratio [OR], 3.89; 95% confidence interval [CI], 1.06-14.20; P = 0.04) and admission serum fibrinogen level <2.5 g/L (OR, 6.15; 95% CI, 1.67-22.67; P = 0.006) were significantly associated with 6-month mortality. In addition, admission serum fibrinogen level was negatively correlated with delayed cerebral ischemia, and admission serum fibrinogen level <2.5 g/L (OR, 3.86; 95% CI, 0.99-15.09; P = 0.05) was also significantly associated with delayed cerebral ischemia. CONCLUSIONS: Patients with poor-grade aSAH with reduced admission fibrinogen level have a higher risk of delayed cerebral ischemia and 6-month mortality compared with those without. The admission serum fibrinogen level might be useful as a predictor and treatment target in patients with poor-grade sSAH who have undergone surgical treatment.
