Area of Science:

  • Neurosurgery
  • Neurological Surgery
  • Skull Base Surgery

Background:

  • Resection of lesions adjacent to the lateral ventricle presents surgical challenges.
  • Minimally invasive techniques are crucial for improving patient outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of the contralateral transcallosal approach.
  • To demonstrate its utility in accessing lateral ventricular lesions.

Main Methods:

  • Modified transcallosal technique involving specific head positioning and contralateral dissection.
  • Application in 32 patients with diverse lesions (cavernous malformations, arteriovenous malformations, tumors).

Main Results:

  • Complete resection achieved for cavernous malformations, benign tumors, and some arteriovenous malformations.
