Preoperative Prediction of Outcome in 283 Poor-Grade Patients with Subarachnoid Hemorrhage: A Project of the Chugoku-Shikoku Division of the Japan Neurosurgical Society

Abstract

Advanced age, WFNS grade V, improvement in WFNS grade, and LDA associated with vasospasm on CT were found to be independent predictors of clinical outcome, whereas rebleeding, early aneurysm surgery and treatment modality (surgical clipping or Guglielmi detachable coil embolization) were not independently associated with outcome in patients with poor-grade aneurysm.
