Head Position After Endovascular Therapy

The optimal head position for patients with acute ischemic stroke (AIS) remains uncertain. The HeadPoS study revealed that there is no significant difference in disability outcomes between patients who are placed in a lying-flat position for 24 hours and those who are placed in a sitting-up position with the head elevated to at least 30 degrees for 24 hours. However, this study included both patients with ischemic and hemorrhagic strokes, and most of the patients had mild strokes (median National Institutes of Health Stroke Scale score of 4). It is unclear how to arrange the patient's head position after endovascular treatment. The hypothesis of this trial: Compared with the lying flat head positioni, the head elevation position after endovascular treatment can significantly improve the 90-day functional outcome of acute large vessel occlusion in the anterior circulation.
