    Surgical interventions for vertebrobasilar insufficiency can be guided by cerebral angiography. This study details 52 brainstem revascularization procedures, highlighting how imaging directs surgical approaches for better patient outcomes.

    Area of Science:

    • Neurosurgery
    • Vascular Surgery
    • Neuroradiology

    Background:

    • Vertebrobasilar insufficiency (VBI) poses significant neurological challenges.
    • Surgical management for VBI has advanced considerably in recent years.
    • Cerebral angiography is essential for diagnosing VBI and planning surgical interventions.

    Purpose of the Study:

    • To analyze the role of preoperative angiographic findings in guiding surgical approaches for VBI.
    • To report the outcomes of various brainstem revascularization procedures.
    • To describe technical aspects of surgical techniques and neuroradiological contributions.

    Main Methods:

    • Retrospective analysis of 52 patients undergoing brainstem revascularization between 1979 and 1985.
    • Review of preoperative and postoperative cerebral angiograms.

  • Detailed description of surgical procedures including bypasses and endarterectomies.

    • Main Results:

    • Fifty-two patients underwent procedures: occipital artery to cerebellar artery bypasses (17), intracranial vertebral endarterectomies (4), superficial temporal to cerebellar/cerebral artery bypasses (31).
    • Preoperative angiograms were crucial in localizing disease and determining the surgical strategy.
    • Postoperative angiograms confirmed the technical success of the interventions.

    Conclusions:

    • Cerebral angiography effectively guides surgical selection and approach for vertebrobasilar insufficiency.
    • Brainstem revascularization procedures, as detailed, represent a viable surgical option for VBI.
    • The collaboration between neuroradiologists and surgeons is vital for successful VBI management.
