摘要

Recent case reports suggest that endovascular recanalization may be safe and feasible for vertebral artery occlusion (VAO) patients without a stump, however, comprehensive management strategies for endovascular recanalization remain poorly understood. In this technical note, we describe the REVANS technique in patients with VAO lacking a stump. The REVANS technique demonstrates promise as a viable option for managing symptomatic non-acute VAO without a visible stump. This approach leverages cervical collateral vessels to retrogradely access and recanalize occluded vertebral artery segments, offering potential benefits in improving patient outcomes.
