This novel endoscopic technique uses ultrasound guidance and laser assistance for treating brain lesions. It offers a low-risk alternative to traditional neurosurgery with minimal trauma and short operation times.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Procedures
  • Medical Technology

Background:

  • Conventional neurosurgical techniques for intracranial lesions can involve significant trauma and longer recovery periods.
  • There is a need for advanced, minimally invasive approaches to manage diverse intracranial pathologies.

Purpose of the Study:

  • To describe and evaluate an ultrasound-guided, laser-assisted, and TV-controlled endoscopic technique for intracranial lesion management.
  • To assess the efficacy and safety of this technique in a patient cohort.

Main Methods:

  • The technique involves CT/MRI reconstruction, burr-hole placement, and ultrasound-guided endoscopic navigation.
  • A rigid endoscope with integrated suction, irrigation, Neodymium Yag laser, and microinstrument channels was utilized.

  • A TV camera attachment enabled real-time visualization and control, ensuring sterility.

    • Main Results:

    • The technique was applied to 133 patients with various intracranial lesions, including 77 spontaneous intracerebral hematomas and 24 brain tumors.
    • Successful evacuation or resection was achieved in a significant percentage of hematoma and tumor cases.
    • The complication rate was 1.6%, with 1.6% morbidity and 0% mortality.

    Conclusions:

    • The described endoscopic technique is a viable, low-risk alternative to conventional neurosurgery for specific intracranial lesions.
    • Its minimal surgical trauma, short operation time, and high-tech integration contribute to favorable patient outcomes.
