Neurosurgery Preoperative Procedures Quiz

Treatment of Resectable Low-Grade Gliomas

• Surgical Resection: Complete surgical resection is the primary treatment choice for patients with resectable low-grade gliomas, aimed at removing as much of the tumor as possible.
• Adjuvant Therapy: Patients may require additional treatments such as radiotherapy or chemotherapy after surgery, depending on tumor characteristics and patient condition.

Purpose of Steroids in Surgery

• Reduce Edema: Corticosteroids are utilized to minimize perioperative cerebral edema, which can relieve pressure on surrounding brain tissue.
• Decrease Inflammation: They help in managing inflammation and improving recovery outcomes following surgery.

Guiding Limits of Resection

• Functional Mapping: In some cases, intraoperative functional mapping techniques help define safe surgical limits to preserve critical brain functions while aiming for maximal tumor removal.
• MRI Localization: Advanced imaging such as MRI can assist in determining tumor boundaries and planning surgical approaches.

When Surgery is Not Feasible

• Patient's Clinical Status: Conditions such as significant comorbidities or poor overall health might render surgery too risky for certain patients.
• Tumor Location: Tumors situated in eloquent brain areas, where surgery could lead to major functional impairments, might also limit surgical options.
