BackgroundTreatment outcomes of octogenarians with aneurysmal subarachnoid hemorrhage (aSAH) are often considered poor. With ongoing advancements and experience in endovascular technology, we sought to evaluate the outcomes of octogenarians treated for aSAH in the second post-International Subarachnoid Aneurysm Trial (ISAT)/Barrow Ruptured Aneurysm Trial (BRAT) decade.MethodA single-center database of aSAH was reviewed to identify patients aged 80 years or above undergoing aneurysm treatment. Mortality and favorable neurologic outcome (defined as modified Rankin Scale score <3) were assessed among the series and compared across several subgroups.ResultsOctogenarian patients constituted 6% of the aSAH cohort (38 of 619) over the reviewed period. Twenty-one percent were high grade (Hunt-Hess grade 4-5). Endovascular treatment was the first-line modality in 90% of patients. During a median follow-up of 17 months, the overall mortality was 39%. Higher mortality was associated with poor Hunt-Hess grade (100% for grade 5, 47% for III-IV, 13% for 1-2, P = 0.004) and non-independent baseline function status (100% mortality for non-independent vs. 28% for independent group, P = 0.002). At last follow-up, 53% of patients achieved a favorable neurologic outcome. The stratified rate was 80% in Hunt-Hess grade I-II and over 60% in patients with premorbid independent function status or less than 5 frailty components (P ≤ 0.02 vs. poorer counterparts).ConclusionsNeurologic outcomes of octogenarian patients with aSAH are improving in the second post-trial decade, particularly given the preponderance of endovascular treatment. Baseline functional status and comorbidities of octogenarians should be considered in addition to the Hunt-Hess grade in prognostication.Copyright © 2024 Elsevier Inc. All rights reserved.
