Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Isolated vertebral artery occlusions (VAO) account for approximately one third of posterior circulation occlusions, but have been given the least attention among posterior circulation strokes. If the two recent ATTENTION and BAOCHE randomized clinical trials have proven the superiority of endovascular thrombectomy (EVT) in basilar artery occlusions, data on the effectiveness and harm of acute revascularization treatment on isolated VAO is scarce. We aim to investigate the impact of acute recanalisation treatments in acute ischemic stroke patients with isolated VAO.

In the absence of RCT, observational data with appropriate statistical methods may give indications on benefits and harms of treating neglected stroke situations like acute vertebral occlusion. Results may also lay the basis for prospective studies, such as randomized clinical trials.
