Name of the Procedure:

Replacement or Irrigation of Ventricular Catheter Common terms: Ventricular Catheter Replacement, Ventricular Catheter Irrigation, VP Shunt Revision

Summary

The procedure involves either replacing or flushing a ventricular catheter, which is a small, flexible tube inserted into the brain's ventricles to drain cerebrospinal fluid (CSF) and relieve pressure. This is often part of a shunt system.

Purpose

The procedure addresses issues related to excess cerebrospinal fluid (CSF) in the brain, commonly associated with conditions like hydrocephalus. The goal is to ensure proper CSF drainage to prevent complications such as increased intracranial pressure, headache, nausea, or even more severe neurological effects.

Indications

• Symptoms of shunt malfunction, such as headaches, nausea, lethargy, or changes in mental status.
• Infection or blockage in an existing ventricular catheter.
• Regular maintenance based on medical advice to ensure shunt function.

Preparation

• Patients are typically advised to fast for a certain period before the procedure.
• Medication adjustments, particularly for blood thinners, may be necessary.
• Pre-procedure diagnostic tests such as MRI, CT scans, or shunt series X-rays may be required to assess the condition of the current catheter.

Procedure Description

1. Patient receives general anesthesia.
2. The scalp is shaved and sterilized over the area where the catheter will be accessed.
3. An incision is made to expose the catheter and either replace it with a new one or irrigate the existing one to clear blockages.
4. After ensuring proper function, the incision is closed with sutures.
5. The area is dressed, and sterile bandages are applied.

Tools/Equipment: Scalpels, catheters, endoscopic devices, fluid irrigation systems, sutures, sterilization materials.

Anesthesia: General anesthesia is typically used.

Duration

The procedure usually takes between 1 to 2 hours.

Setting

Performed in a hospital operating room equipped for neurological surgeries.

Personnel

• Neurosurgeon
• Anesthesiologist
• Surgical Nurses
• Operating Room Technicians

Risks and Complications

• Infection at the surgical site
• Bleeding or hemorrhage
• Catheter blockage or malfunction
• Anesthesia-related complications
• Potential need for additional surgeries

Benefits

Restored proper CSF drainage, alleviation of symptoms of increased intracranial pressure, and prevention of further neurological complications. Benefits are generally noticed shortly after the procedure.

Recovery

• Close monitoring in the neurosurgical unit post-operation.
• Follow-up imaging to confirm proper catheter function.
• Oral pain medications to manage discomfort.
• Instructions for wound care and activity restrictions.
• Patients typically recover within a few weeks, but individual recovery times can vary.

Alternatives

• External ventricular drain (temporary solution)
• Endoscopic third ventriculostomy (for certain types of hydrocephalus)
• Medical management with drugs to reduce CSF production (less effective)

Pros and Cons: Each alternative comes with its own risks and benefits which should be discussed with the healthcare provider.

Patient Experience

During the procedure, the patient will not feel pain due to general anesthesia. Post-procedure, they might experience some pain and discomfort at the incision site, which is managed with medications. Most patients report significant symptom relief following recovery.
