Summary
This study demonstrates a reliable method for cryodestruction of deep brain structures using the PAH device, achieving precise lesion volumes with minimal complications in 352 patients with central nervous system diseases.
Area of Science:
- Neurosurgery
- Neurology
- Cryosurgery
Context:
- Functional stereotactic operations are crucial for treating chronic progressive central nervous system diseases.
- Precise targeting of deep subcortical structures is essential for therapeutic efficacy.
Purpose:
- To evaluate the efficacy and safety of a cryodestruction method for deep subcortical structures.
- To assess the repeatability and complication rates of cryosurgery in neurosurgical interventions.
Summary:
- The PAH device utilizes solid carbon dioxide for cooling brain tissues to -70°C, creating focal lesions of 0.2 or 1 cm³.
- The method was applied to 352 patients, demonstrating high repeatability of geometric parameters for the destruction foci.
- The procedure showed an absence of significant local or systemic tissue reactions and a low incidence of hemorrhagic and infectious complications.
Impact:
- This cryodestruction technique offers a repeatable and safe approach for functional stereotactic neurosurgery.
- The findings support the use of this method for managing chronic progressive central nervous system disorders.
- Minimizing complications enhances patient outcomes in neurosurgical interventions.
