CT-guided computer-assisted stereotactic resection of brain tumours

Area of Science:

• Neurosurgery
• Medical Imaging
• Computer-Assisted Surgery

Background:

• Intracerebral lesions require precise surgical removal.
• Traditional stereotactic techniques can be limited in complex cases.
• Advancements in imaging and computing offer new possibilities for surgical guidance.

Purpose of the Study:

• To develop and evaluate a computer-assisted technique for CT-guided stereotactic microsurgical resection of small intracerebral lesions.
• To assess the safety and efficacy of this novel approach in a clinical setting.
• To integrate advanced software and hardware for enhanced surgical precision.

Main Methods:

• Development of a computer-assisted technique utilizing CT imaging.
• Design of an original stereotactic retractor compatible with existing equipment.
• Implementation of a software program for treatment planning and intraoperative guidance.
• Application of the technique in 6 patients with various supratentorial intracerebral lesions.

Main Results:

• Successful microsurgical resection of lesions ranging from 18 to 30 mm.
• No mortality or significant morbidity observed post-procedure.
• Karnofsky Performance Status (KPS) scores remained unchanged in 3 patients and improved in 3 patients.
• Accurate removal of pathological tissues within CT-defined boundaries.

Conclusions:

• The developed computer-assisted CT-guided stereotactic microsurgical technique is safe and effective for small intracerebral lesions.
• This method allows for precise localization, safe exposure, and complete tumor removal.
• The integration of software and specialized hardware enhances surgical outcomes and patient performance status.
