    ObjectiveDemographic changes are leading to an aging society with a growing number of patients with cardiovascular diseases, relying on antiplatelet drugs like acetylsalicylic acid (ASA). Although antiplatelet agents are suspected to be protective not only in the cardiologic but in the neurovascular field, the alteration of the coagulating process could have a major impact on the course and outcome after rupture of intracranial aneurysms.MethodsBetween June 1999 and December 2014, 1422 patients were treated for aneurysmal SAH in our institution, 144 (10.1%) with continuous ASA at the time of aneurysm rupture. A matched-pair analysis was performed.ResultsThe rate of patients with continuous ASA treatment while rupture of the aneurysm is rising significantly (P < 0.01). Those patients were significantly older than patients without ASA (60 vs. 53 years, P < 0.001). ASA-treated patients more often had aneurysmal rebleeding (4.7% vs. 2.3%, P = 0.3) and treatment-related hemorrhagic complications (13.9% vs. 6.2%, P = 0.06). However, rates were not different in microsurgical or endovascular procedures (16.4% vs. 12.2%, P = 0.6). Favorable outcome (Modified Rankin Scale 0-2) was achieved in 49.3% of the ASA group and 52.1% of the control group (P = 0.7).ConclusionPatients with continuous ASA treatment were significantly older than patients without ASA, but there was no difference in admission status or bleeding pattern. Outcome was not different in the matched-pair analysis. There was no statistical difference in treatment related-complication rates of microsurgical and endovascular procedures. Therefore, ASA use should not influence treatment decision of the ruptured aneurysm.Copyright © 2018 Elsevier Inc. All rights reserved.
