Objective: We investigated in-hospital stroke (IHS) treated by mechanical thrombectomy in comparison with out-of-hospital stroke (OHS) to clarify the points of concern in IHS at our institution.

Methods: Between September 2015 and June 2018, 19 patients with IHS who underwent mechanical thrombectomy (IHS group) were enrolled, and compared with 154 patients with OHS (OHS group) regarding patient characteristics, technical results, and outcome.
