Basilar artery occlusion (BAO) is an uncommon event, and leads to poor outcome in an estimated 60 to 80% of patients. Two early randomized trials, BASICS and BEST demonstrated equivocal benefit of endovascular therapy (EVT) compared to medical management. These trials helped in forming the design, sample size and eligibility criteria for the subsequent two trials, ATTENTION and BAOCHE which demonstrated superiority of EVT over medical management. In this commentary, we look at the evolution of how early BAO studies formed the building blocks for successive BAO trials, review lessons learned, and opportunities for future research.
