Objective: The objective of the study was to evaluate the outcome and related factors in patients with aneurysmal subarachnoid hemorrhage (aSAH). Materials and Methods: Clinical data of 221 patients who were diagnosed with spontaneous SAH due to ruptured intracranial aneurysm and surgically treated at Vajira Hospital between January 2013 and May 2016 were retrospectively reviewed. Patient and aneurysm characteristics, clinical status at presentation, treatment, and status at discharge and 1 year after discharge were recorded. Outcomes 1 year after surgery were assessed using the Glasgow Outcome Scale (GOS). Patients were divided into two groups according to the GOS score: the favorable outcome group (GOS scores 4 and 5) and unfavorable outcome group (GOS scores 1–3). Results: Among the 221 study patients, 158 were classified in the favorable outcome group and 63 in the unfavorable outcome group. Patient age, Hunt and Hess grade, aneurysm size, use of Vitamin C solution irrigation in the subarachnoid space, and GOS score 1 year after surgery significantly differed between the two groups. Conclusions: Numerous factors analyzed in this study were significantly associated with 1-year outcome in surgically treated aSAH patients, including subarachnoid Vitamin C irrigation. Further study of subarachnoid Vitamin C irrigation is warranted.
