STROKE, HYPOPERFUSION, ARTERY OCCLUSION
Endovascular thrombectomy (EVT) is the standard treatment to improve functional outcomes in acute ischemic stroke patients with large vessel occlusion.Among patients with successful reperfusion with EVT, residual blood flow impairment is of two types: macrocirculatory—angiographically visible occlusions in more distal arteries; and microcirculatory—no reflow at the arteriolar–capillary level despite absence of any angiographically visible occlusion. For example, in patients with eTICI 3 outcome, no visible occlusions are present but hypoperfusion throughout the field may occur due to microcirculatory obstructions.Intracranial large artery atherosclerotic (LAA) stroke is one of the most common etiologies of large artery occlusion, especially in Asian patients.
