Grading of Subarachnoid Hemorrhage: Modification of the World Federation of Neurosurgical Societies Scale on the Basis of Data for a Large Series of Patients.

摘要: Objective The goals of this study were to use a large, prospectively collected, multicenter database for patients with aneurysmal subarachnoid hemorrhage (SAH) who treated between 1991 and 1997 determine the prognostic significance clinical radiological factors outcomes those develop grading scale predict outcomes. Methods A total 3567 SAH entered into four randomized trials tirilazad studied. Outcomes assessed 3 months after SAH, Glasgow Outcome Scale. Twenty univariate multivariate analyses, Grading scales based on most powerful parameters statistically derived validated compared World Federation Neurosurgical Societies (WFNS) scale. Results Factors predictive included age, WFNS grade, history hypertension, systolic blood pressure at admission, ruptured aneurysm location size, clot thickness computed tomographic scans, angiographic vasospasm admission. using these could be derived; it predicted more accurately than did scale, although would complex use. Conclusion prediction can improved by adding additional albeit added complexity.
