Area of Science:

  • Neurosurgery
  • Vascular Neurology
  • Surgical Anatomy

Background:

  • Large and complex aneurysms in the posterior circulation (vertebrobasilar system) pose significant surgical challenges.
  • Advancements in cranial base surgery have introduced novel strategies for managing these complex cerebrovascular diseases.

Purpose of the Study:

  • To evaluate the efficacy and application of four distinct cranial base surgical approaches for treating large and/or complex aneurysms of the posterior circulation.
  • To propose a management paradigm for these challenging aneurysms based on surgical outcomes.

Main Methods:

  • Retrospective analysis of 30 patients treated for large/complex posterior circulation aneurysms.
  • Surgical treatment involved one of four cranial base approaches: extradural temporopolar, combined petrosal, retrolabyrinthine-transsigmoid, or extreme-lateral inferior transtubercular exposure.

  • Detailed discussion of indications, surgical techniques, and outcomes for each approach.

    • Main Results:

    • The study details the application and outcomes of the four specific cranial base approaches in a cohort of 30 patients.
    • Specific results regarding the technical feasibility, safety, and efficacy of each approach are presented.
    • The series demonstrates the utility of cranial base strategies in managing complex vertebrobasilar aneurysms.

    Conclusions:

    • Cranial base surgical approaches provide viable and effective options for managing large and complex posterior circulation aneurysms.
    • The study suggests a structured management paradigm to guide the selection of appropriate cranial base techniques for these challenging neurosurgical cases.
