    The V2 segment bypass connects the cervical carotid artery to the extracranial vertebral artery, facilitating communication between anterior and posterior circulations.

  • 2

    This bypass technique offers advantages such as higher-pressure flow, physiological inflow, and avoidance of invasive skull base surgery.

  • 3

    The study expands the indications for the V2 bypass to include posterior circulation ischemia, subclavian steal syndrome, and compensatory terminal basilar artery aneurysms.

  • 4

    Preoperative assessments included the NIH Stroke Scale, and surgical indications were categorized into three types based on vascular occlusions.

  • 5

    The V2 bypass represents a significant advancement in cerebral revascularization, evolving from traditional low-flow EC-IC bypass techniques.
