At least seven randomized controlled trials have consistently shown that endovascular treatment can improve the functional outcome of stroke patients with acute anterior large vessel occlusion. However, these trials did not include patients with large vessel occlusion in the posterior circulation.~The hypothesis of this trial: Compared with standard medical treatment alone, standard medical treatment combined with endovascular treatment can significantly improve the 90-day functional outcome of acute large vessel occlusion in the posterior circulation.
The aim of this trial is to investigate whether endovascular treatment can improve the 90-day functional outcome of acute large vessel occlusion in the posterior circulation.
