Summary

The VAST study is a single-center prospective observational study that enrolled individuals with acute ischemic stroke (AIS) within 24 hours onset. The patients will receive neurological examination, multimodal computed tomographic perfusion (CTP) or multimodal magnetic resonance perfusion (MRP) before reperfusion therapy. The hypoperfusion volume, ischemic core volume, brain edema, cerebral arterial collaterals will be evaluated on baseline brain image. The status of cerebral venous system (CVs) including superficial middle cerebral vein, vein of Labbe, vein of Trolard, Sphenoid sinus, thalamostriate vein, Internal cerebral vein, Rosenthal's vein will be evaluated in phases of reconstructed imaging from CTP/MRP. The investigators will explore the venous markers for prognosis of AIS patients who received reperfusion therapy, and find the role of venous system in reperfusion injury.
