Name of the Procedure:

Craniectomy or Craniotomy with Excision of Foreign Body from the Brain

Summary

A craniectomy or craniotomy with excision of a foreign body from the brain is a surgical procedure involving the removal of part of the skull to access the brain and extract foreign materials like shrapnel, bullets, or other debris that may have penetrated brain tissue.

Purpose

This procedure is performed to remove foreign objects that have entered the brain, often due to traumatic injuries. The primary goal is to prevent further brain damage, reduce the risk of infection, relieve pressure on the brain, and improve neurological outcomes.

Indications

• Traumatic brain injury with embedded foreign bodies
• Symptoms such as severe headache, seizures, neurological deficits, or signs of increased intracranial pressure
• Imaging studies (e.g., CT or MRI scans) showing foreign objects lodged in brain tissue

Preparation

• Pre-procedure fasting for at least 8 hours
• Adjustment or temporary discontinuation of certain medications like blood thinners
• Pre-operative imaging studies (CT or MRI) to locate the foreign body
• Baseline neurological assessment and blood tests

Procedure Description

1. The patient is placed under general anesthesia.
2. The head is secured in a stable position.
3. The surgeon makes an incision in the scalp and removes a section of the skull (craniectomy) or creates a hinged opening (craniotomy).
4. Using advanced imaging techniques, the surgeon locates and carefully extracts the foreign body.
5. Any damaged brain tissue is repaired, and the area is thoroughly cleaned to prevent infection.
6. The removed skull piece is replaced (in craniotomy) and secured, or the wound is closed if the bone is left off to reduce swelling (in craniectomy).
7. The scalp incision is then sutured closed.

Duration

The procedure typically lasts 3 to 5 hours, depending on the complexity and location of the foreign body.

Setting

It is performed in a hospital operating room under sterile conditions.

Personnel

• Neurosurgeon
• Surgical nurses
• Anesthesiologist
• Operating room technician

Risks and Complications

• Infection
• Bleeding or hematoma
• Seizures
• Brain swelling
• Neurological deficits (weakness, speech problems, etc.)
• Reaction to anesthesia

Benefits

• Removal of potentially harmful foreign objects
• Reduction in intracranial pressure
• Prevention of infection and further brain injury
• Improvement in neurological function

Recovery

• Initial intensive care unit (ICU) monitoring followed by transfer to a regular hospital room
• Pain management with medications
• Follow-up imaging to ensure successful removal and detect any complications
• Physical therapy or rehabilitation if needed
• Gradual return to normal activities over several weeks
• Follow-up appointments with the neurosurgeon

Alternatives

• Non-surgical management, which may be considered if the foreign body is small and not causing significant symptoms
• Less invasive endoscopic procedures in select cases
• Risks and benefits need to be carefully weighed for each alternative

Patient Experience

• During the procedure: The patient will be under general anesthesia and will not feel pain.
• After the procedure: The patient may experience headache, fatigue, and discomfort at the incision site, managed with pain medications. Close monitoring and supportive care will be provided to ensure a smooth recovery.
