Demographic, Clinical, and Imaging Predictors of Outcomes in Aneurysmal Subarachnoid Hemorrhages
Abstract
Aneurysmal subarachnoid hemorrhage (aSAH) outcomes depend on demographic, clinical, and imaging features, as demonstrated through examination of an 82-patient series. Demographically, the series' mean age was 49.7 years (range: 30–70) with a female predominance (65.8%). Clinically, there were lower Glasgow Coma Scale (GCS) scores (mean: 13.3) and increased Hunt and Hess grades (mean: 1.87, range: 1–3), while hydrocephalus requiring intervention was encountered in 6.1% of cases. Imaging predictors were an overall CT-confirmed subarachnoid hemorrhage, 18.3% of which developed cerebral infarction and 6.2% required ventricular-peritoneal shunting. Large interventions such as surgical clipping (100% of patients) and external ventricular drainage (8.5% use) were associated with management outcomes. Despite limited by the fineness of outcome information, this assessment delineates the prognostically significant contribution of acute clinical state (GCS, Hunt and Hess grade) and secondary complication (infarction, hydrocephalus) in a SAH.
