IntroductionDespite technical advances in mechanical thrombectomy (MT), failure to achieve recanalization in the posterior circulation remains a significant challenge. Rescue strategies to increase MT success in the posterior circulation have been explored. Mechanical thrombectomy failed after several unsuccessful passes (Fig 1).
