In large vessel occlusion (LVO) stroke, it is unclear whether severity of ischemia is involved in early post-thrombolysis recanalization over and above thrombus site and length. Here we assessed (...)
-
Background and Purpose- In acute stroke patients with large vessel occlusion, the goal of intravenous thrombolysis (IVT) is to achieve early recanalization (ER). Apart from occlusion site and (...)
-
Background and Purpose- Whether bridging therapy, that is, intravenous thrombolysis [IVT] followed by mechanical thrombectomy, is beneficial as compared with IVT alone in minor stroke (National (...)
