Abstract
Optimal definitive treatment timing for patients with aneurysmal subarachnoid hemorrhage (aSAH) remains controversial. We compared outcomes for aSAH patients with ultra-early treatment versus later treatment at a single large center. Patients who received definitive open surgical or endovascular treatment for aSAH between January 1, 2014, and July 31, 2019, were included. Ultra-early treatment was defined as occurring within 24h from aneurysm rupture. The primary outcome was poor neurologic outcome (modified Rankin Scale score > 2). Propensity adjustment was performed for age, sex, Charlson Comorbidity Index, Hunt and Hess grade, Fisher grade, aneurysm treatment type, aneurysm type, size, and anterior location. Of the 1013 patients (mean [SD] age, 56 [14] years; 702 [69%] women, 311 [31%] men) included, 94 (9%) had ultra-early treatment. Compared with the non-ultra-early cohort, the ultra-early treatment cohort had a significantly lower percentage of saccular aneurysms (53 of 94 [56%] vs 746 of 919 [81%], P <0 .001), greater frequency of open surgical treatment (72 of 94 [77%] vs 523 of 919 [57%], P <0 .001), and greater percentage of men (38 of 94 [40%] vs 273 of 919 [30%], P = .04). After adjustment, ultra-early treatment was not associated with neurologic outcome in those with at least 180-day follow-up (OR = 0.86), the occurrence of delayed cerebral ischemia (OR = 0.87), or length of stay (exp(β), 0.13) (P ≥ 0.60). In a large, single-center cohort of aSAH patients, ultra-early treatment was not associated with better neurologic outcome, fewer cases of delayed cerebral ischemia, or shorter length of stay.
