Abstract
Collateral circulation that determines infarct progression in large vessel occlusion (LVO) is implicitly regarded as stationary. We investigated collateral circulation changes during interfacility transfer for endovascular thrombectomy (EVT) and its association with functional outcome in anterior circulation LVO stroke. Seventy consecutive patients with middle cerebral artery occlusion transferred…
