Surgical clipping of pericallosal aneurysms is challenging. A partial corpus callosum resection technique improves proximal vessel exposure, enabling safe aneurysm treatment without hemispheric disconnection.

Area of Science:

  • Neurosurgery
  • Vascular Neurosurgery
  • Cerebral Aneurysm Treatment

Background:

  • Pericallosal aneurysms, particularly at the origin of the pericallosal artery, present significant surgical challenges due to limited proximal vasculature exposure.
  • Standard craniotomy techniques may not provide adequate visualization for safe and effective surgical intervention.

Observation:

  • This report details a modified surgical approach involving partial resection of the corpus callosum.
  • This technique was applied in two patients undergoing surgery for pericallosal aneurysms.

Findings:

  • The partial corpus callosum resection yielded excellent exposure of the A2 segment of the anterior cerebral artery.
  • Both patients' aneurysms were successfully clipped with no intraoperative or postoperative complications related to the resection.

  • No signs of hemispheric disconnection were observed in either patient post-surgery.

    • Implications:

    • Partial corpus callosum resection is a viable technique to enhance surgical access for treating proximal pericallosal aneurysms.
    • This approach may reduce the technical difficulty and improve safety outcomes in complex aneurysm surgeries.
    • Further studies could explore the long-term functional outcomes and applicability of this technique in a broader patient cohort.
