Future challenges of stroke treatment

Posterior circulation stroke accounts for approximately 20% of all ischaemic strokes. Acute basilar artery occlusion (BAO) is one of the most severe conditions, it is associated with death or major disability in more than three quarters of the cases, and its optimal management remains unestablished. Currently, the treatment is based primarily upon consensus, the clinical practice varies widely, and the actual benefit of mechanical thrombectomy has to be fully estimated. Although the recent years have profoundly revolutionized and improved the stroke care, many questions still remain unanswered and will represent the challenges of the next future.
