Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Neurology

Background:

  • Cavernous malformations are vascular brain lesions that can cause seizures, headaches, and hemorrhage.
  • Surgical resection is a treatment option, but deep-seated lesions pose challenges.
  • Minimally invasive techniques are sought to improve safety and efficacy.

Purpose of the Study:

  • To evaluate the safety and efficacy of interactive image-guided surgery for deep-seated cavernous malformations.
  • To assess the rate of complete resection and clinical outcomes.
  • To determine the incidence of postoperative complications.

Main Methods:

  • Fifteen patients with cavernous malformations underwent interactive image-guided resection.
  • Diagnosis utilized magnetic resonance imaging and digital subtraction angiography.

  • Awake craniotomy with functional mapping and intraoperative infrared imaging were employed for eloquent area lesions.
  • Robotic microscopy was introduced in 1996.

    • Main Results:

    • Complete surgical resection was achieved in all 15 patients, confirmed by postoperative MRI.
    • Postoperative transient neurological deficits occurred in 13.3% of patients, resolving within 6 months.
    • No mortality was associated with the procedure.
    • 13 patients experienced complete symptom recovery, and 2 with seizures showed marked improvement.

    Conclusions:

    • Interactive image-guided surgery is a highly accurate and safe method for resecting deep-seated cavernous malformations.
    • The technique facilitates complete tumor removal and leads to favorable clinical outcomes.
    • It offers a promising approach for managing complex brain vascular lesions.
