Article
Introduction Despite recent advances in endovascular therapy, up to half of acute ischemic stroke patients experience incomplete reperfusion (expanded Thrombolysis in Cerebral Infarction, eTICI<3) after intervention. However, many of these patients will achieve complete delayed reperfusion at the 24h follow‐up, which is linked to good clinical outc...
