Computer-assisted neuronavigation for cerebral cavernous malformations surgery minimizes brain trauma and neurological deficits. This image-guided approach ensures accurate targeting and safe resection, leading to improved patient outcomes.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Neurology

Background:

  • Intracranial lesion surgery, particularly for cerebral cavernous malformations (CCMs), faces challenges in minimizing brain trauma and neurological deficits.
  • Computer-assisted image guidance, or neuronavigation, offers a potential solution to enhance surgical precision and safety.

Purpose of the Study:

  • To evaluate the efficacy and safety of neuronavigation-assisted surgery for the resection of cerebral cavernous malformations.
  • To assess the impact of image-guided surgery on neurological outcomes and surgical morbidity.

Main Methods:

  • Preoperative MRI data sets were used for surgical planning with a neuronavigation system (STP 4.0, SNN).
  • Functional MRI images were fused preoperatively for CCMs located near eloquent brain regions.

  • Twenty-one patients underwent neuronavigation-assisted surgery for CCM resection over 24 months.

    • Main Results:

    • The mean CCM size was 18.3 mm (range 5-60 mm), with a mean cortical distance of 26 mm (range 5-50 mm).
    • The median surgical duration was 180 minutes.
    • All patients experienced identical or improved neurological outcomes post-surgery.

    Conclusions:

    • Neuronavigation enables accurate intraoperative targeting and a precise surgical approach for CCM resection.
    • Image-guided surgery facilitates a comfortable, safe, and minimally invasive procedure, minimizing tissue manipulation.
    • Neuronavigation-assisted surgery is a safe and effective method for treating cerebral cavernous malformations, improving patient neurological status.
