Subarachnoid hemorrhage in elderly: Advantages of the endovascular treatment

Subarachnoid hemorrhage (SAH) from aneurysm rupture accounts for approximately 3% of all strokes. A significant improvement in surgery and endovascular procedures has reduced mortality and morbidity. Nowadays, endovascular treatment is a viable alternative to conservative treatment in elderly patients. We designed a retrospective observational study on all endovascular procedures carried out in our department in order to evaluate the outcome in elderly patients compared with a younger cohort.A total of 378 patients with aneurysmal SAH were treated with detachable platinum coils in our department (1994-2009). Of these, 310 patients were aged 20-69 years and 68 were aged over 70 years. Data were stratified according to Hunt-Hess (H-H) grade at admission. The mean follow up was 4.8 years. The final outcome was evaluated through the Glasgow Outcome Scale (GOS).We observed a favorable outcome (GOS 5-4) in both groups of patients admitted with moderately good clinical conditions (H-H 1-3), with no statistically significant difference. In contrast, in the case of H-H grade at admission > 3, we observed a statistically significant poor outcome in elderly patients.We consider the endovascular treatment as first choice for elderly patients presenting with a good H-H grade at admission. Quick functional recovery and reduced hospitalization time were observed. Unlike young patients, a chance of recovery in elderly patients with H-H 4-5 is more difficult to achieve. Therefore, a conservative approach should be considered.
