Study Notes
Brain Tumor Resection
What is Brain Tumor Resection?
- A surgical procedure to remove a tumor from the brain
- Goal: to remove as much of the tumor as possible while preserving brain function and minimizing damage to surrounding brain tissue
Types of Brain Tumors
- Benign tumors: non-cancerous, slow-growing, and less likely to recur
- Malignant tumors: cancerous, fast-growing, and more likely to recur
- Primary brain tumors: originate in the brain (e.g., glioblastoma, medulloblastoma)
- Metastatic brain tumors: originate from other parts of the body and spread to the brain (e.g., lung, breast, colon cancer)
Steps Involved in Brain Tumor Resection
-
Pre-operative planning:
- Imaging studies (MRI, CT scans) to locate and define the tumor
- Neuropsychological testing to assess cognitive function
-
Surgery:
- Craniotomy: opening the skull to access the tumor
- Tumor removal: using a combination of surgical instruments and techniques (e.g., suction, cautery, ultrasound)
- Closure: repairing the skull and closing the incision
-
Post-operative care:
- Monitoring for complications (e.g., bleeding, infection, seizures)
- Managing pain and discomfort
- Rehabilitation to regain lost function and mobility
Surgical Techniques
- Open craniotomy: traditional surgical approach with a large incision
- Minimally invasive craniotomy: smaller incision, less tissue damage, and faster recovery
- Awake craniotomy: patient is awake during surgery to monitor brain function and minimize damage
- Image-guided surgery: using intraoperative imaging to guide tumor removal
Risks and Complications
- Surgical risks: bleeding, infection, seizures, stroke, and brain edema
- Post-operative complications: cognitive impairment, speech and language difficulties, and motor weakness
- Recurrence: tumor regrowth or new tumor formation
Advances in Brain Tumor Resection
- Neuronavigation: using computer-assisted navigation to enhance surgical accuracy
- Intraoperative imaging: real-time imaging during surgery to guide tumor removal
- Robot-assisted surgery: using robotic systems to enhance precision and dexterity
