1. Procedure Overview
Brain stereotactic surgery is a minimally invasive technique that uses a 3D coordinate system to locate and target specific areas within the brain for diagnosis or treatment. It is commonly used for:
Biopsy of deep-seated brain tumors or lesions
Drainage of cysts or abscesses
Implantation of electrodes (e.g., for deep brain stimulation)
Precise delivery of treatment (e.g., radiosurgery)
Using advanced imaging (CT or MRI) and a stereotactic frame or frameless system, surgeons can accurately navigate the brain with minimal disruption to surrounding tissues.
2. Type of Anesthesia
Depending on the specific procedure and patient condition, local anesthesia with sedation or general anesthesia may be used. For biopsies, patients are often awake but sedated to monitor neurological responses.
3. Possible Risks and Complications
Bleeding or hematoma at the site of surgery
Infection
Seizures
Temporary or permanent neurological deficits
Headache or swelling at the entry point
Complications related to anesthesia
4. Hospital Stay Duration
The hospital stay is generally short, often 1 to 3 days, especially when the procedure is diagnostic or involves minor interventions.
5. Important Post-Operative Care
Observation for any neurological changes
Pain management
Monitoring for signs of infection or bleeding
Follow-up imaging to assess the result of the procedure
If a biopsy is done, pathology results guide further treatment.
