Abstract
Background: Favorable imaging profile according to The Alberta Stroke Program Early CT Score (ASPECTS) is an important selection criterion for endovascular therapy in patients with acute stroke from anterior circulation large vessel occlusion (LVO). The goal of this study was analyze the relationship between ASPECTS values and time of arrival to emergency department (ED) after stroke onset, and its impact on patient’s eligibility for endovascular stroke therapy.
Methods: analysts of ASPECTS values in consecutive patients with acute stroke from anterior circulation LVO admitted within 24 hours of onset was performed. Criteria from American Heart Association/American Stroke Association (AHA/ASA) guidelines based on the proposed class I-II recommendations, including the ‘favorable’ ASPECTS range of 6-10 were applied to determine frequency of potentially eligible patients for endovascular stroke therapy.
Results: Of 641 patients with acute ischemic stroke presenting within the first 24 hours of onset, 71 (11%) had anterior circulation LVO. Medium time from arrival to ED to noncontrast head CT was 6 minutes. 72% of patients arrived to ED within the first 6 hours, 18% within 6-12 hours, and 10% within 12-24 hours of symptom onset. Based on ‘favorable’ ASPECTS criterion alone, 80% of patients with anterior circulation LVO who arrive to the ED within the first 6 hours of stroke onset would qualify for endovascular therapy. Of those who arrived to ED within 6-24 hours of stroke onset, 50% had ‘favorable’ ASPECTS.
Conclusions: 50% of patients with stroke from anterior circulation LVO who arrive to ED within 6-24 hours of onset have ‘favorable’ ASPECTS, making them potentially eligible for endovascular stroke therapy.
