RESUMO
Non-acute intracranial artery total occlusion can lead to severe neurological defect and high recurrence rate of stroke.At present, there is no effective treatment recommended by the guidelines.Traditional treatment methods include medical therapy, extracranial-intracranial bypass surgery and minimally invasive endovascular recanalization therapy.In recent years, with the development of microsurgical vascular anastomosis technique and neurosurgical intervention, and the development of interventional materials, the treatment of non-acute intracranial artery total occlusion has become a hot spots.In this paper, the concept of non on-acute intracranial artery total occlusion, medical therapy, extracranial-intracranial bypass surgery and endovascular interventional therapy are reviewed.
