Craniectomy: Surgery to Relieve Pressure

Overview

  • Definition: A craniectomy is a brain surgery where a part of the skull is removed to relieve pressure on the brain.
  • Purpose: To reduce swelling, pressure, or bleeding that can cause brain damage or be life-threatening.
  • Procedure: The bone piece removed is not immediately replaced; a follow-up surgery called a cranioplasty restores the skull.
  • Types: Decompression craniectomy is a common form used for reducing intracranial pressure.

Conditions Treated

  • Swelling and Pressure: Intracranial hypertension.
  • Bleeding: Hemorrhages or extra fluid collection.
  • Causes: Traumatic brain injury, stroke, blood clots, and hematomas.

Procedure Details

Preparation

  • Urgency: Typically an emergency procedure with little time for preparation.
  • Pre-surgery Requirements: Include a physical exam, blood tests, and imaging tests (X-ray, MRI, CT scan, PET scan, angiography).
  • Medication Adjustments: Possible cessation of blood thinners, and possible prescription of antibiotics or anticonvulsants.

During Surgery

  • Anesthesia: Administered; patients may be awake or asleep depending on surgery type.
  • Surgical Steps:
    • Shaving and cleaning the head.
    • Making an incision and exposing the scalp.
    • Drilling holes and cutting between them to remove a skull piece.
    • Treating the underlying condition.
    • Covering the exposed skull with mesh material.
    • Closing the incision.
  • Duration: Usually 3-5 hours but can vary.

Post-Surgery

  • Recovery Location: Intensive Care Unit (ICU).
  • Post-Surgery Care: Includes wearing a helmet for skull protection, monitoring vital signs, and preparing for cranioplasty.
  • Home Care: Instructions for follow-up care and rest with the head elevated.

Risks and Benefits

Benefits

  • Reduces life-threatening complications and potential brain damage.
  • Success varies based on health and surgery cause.

Risks

  • Potential Complications: Bleeding, hernia, continued pressure, brain damage, infection, seizures, paralysis, mood changes, coma.
  • Recovery Challenges: Increased fall risk, balance and coordination issues.

Recovery and Outlook

Recovery Time

  • Healing: Skull healing may take 1-2 months; full recovery can take years.
  • Activities: Avoid walking unassisted, heavy lifting, driving, manual labor, and exercise until cleared by a surgeon.

Long-Term Care

  • Rehabilitation: Extensive rehab and lifelong care may be necessary.

When to Call the Doctor

  • Urgent Symptoms: Fever, severe pain, cognitive or mood changes, severe headaches.
  • Emergency Symptoms: Seizures, breathing difficulties, stroke signs.
