Abstract only Background: Relatively limited information is available about trends over time in the use of endovascular treatment in patients of different ages hospitalized with acute ischemic stroke and the association between use of thrombectomy treatment and hospital outcomes in age strata. We performed this analysis to evaluate trends in the utilization of endovascular treatment in acute ischemic stroke by age strata in real-world practice. Methods: We conducted this study by identifying patients admitted with a primary diagnosis of ischemic stroke in the United States from 2007 to 2016 using the Nationwide Inpatient Sample. International Classification of Diseases, ninth revision, and tenth, Clinical Modification (ICD-9-CM, ICD-10-CM) codes were used to identify patients admitted for ischemic stroke and undergoing endovascular treatment. Results: Of the 4,590,533 patients admitted with ischemic stroke, 269,922 (5.88%) received intravenous thrombolytic treatment, and 51,375 (1.12%) underwent endovascular treatment. There is almost 12-fold significant increase in the use of endovascular treatment patients admitted with acute ischemic stroke between 2007 to 2016. Patients who were 75 years and older experienced a marked increase in the receipt of endovascular treatment over time (0.12% 2007; 1.91% 2016; trend p
