61544 Craniotomy with elevation of bone flap; for excision or coagulation of choroid plexus

Name of the Procedure:

Craniotomy with elevation of bone flap for excision or coagulation of choroid plexus

Summary

A craniotomy with elevation of bone flap for excision or coagulation of the choroid plexus is a surgical procedure where a section of the skull is temporarily removed to access and remove or cauterize part of the choroid plexus, a network of cells that produce cerebrospinal fluid (CSF) in the brain.

Purpose

This procedure is used to treat conditions related to excessive cerebrospinal fluid production or circulation issues within the brain that may lead to conditions like hydrocephalus. The goals are to alleviate pressure on the brain caused by excessive fluid, reduce symptoms, and prevent further neurological damage.

Indications

• Hydrocephalus (excess fluid accumulation in the brain)
• Tumors or cysts in the choroid plexus
• Persistent cerebrospinal fluid leaks
• Symptoms such as headaches, nausea, vision changes, and neurological deficits attributable to excessive CSF

Preparation

• Fasting typically required 8 hours before the surgery
• Medication adjustments as advised by the healthcare provider
• Preoperative imaging studies such as MRI or CT scans to assess the brain's anatomy
• Blood tests and physical examinations to ensure the patient is fit for surgery

Procedure Description

1. The patient is placed under general anesthesia.
2. An incision is made in the scalp, and a section of the skull bone is removed to create an opening (bone flap).
3. The dura mater (the outer membrane covering the brain) is opened to expose the brain.
4. The surgeon accesses the choroid plexus and removes or cauterizes the problematic tissue.
5. The dura mater is closed, and the bone flap is replaced and secured.
6. The scalp incision is then closed with sutures or staples.

Specialized surgical instruments like cranial drills, retractors, and coagulators are used during the procedure.

Duration

The procedure typically takes between 3 to 5 hours, depending on the complexity of the case.

Setting

Performed in a hospital operating room with access to advanced surgical and monitoring equipment.

Personnel

• Neurosurgeon
• Anesthesiologist
• Surgical nurses
• Operating room technicians

Risks and Complications

• Infection
• Bleeding
• Damage to brain tissue or nerves
• Seizures
• Leakage of cerebrospinal fluid
• Blood clots
• Anesthesia-related risks

Benefits

• Relief from symptoms caused by excess cerebrospinal fluid
• Improvement in neurological function and overall brain health
• Prevention of further complications associated with hydrocephalus or other CSF-related conditions

Recovery

• Initial recovery in the intensive care unit (ICU) for close monitoring
• Pain managed with medication
• Gradual increase in activity levels as directed by the healthcare team
• Follow-up appointments to monitor healing and neurological function
• Full recovery could take several weeks to months, with activity restrictions as advised

Alternatives

• Endoscopic third ventriculostomy (ETV)
• Ventriculoperitoneal (VP) shunt insertion
• Medical management with diuretics (limited effectiveness for some conditions)

Each alternative has its own set of risks, benefits, and success rates which should be discussed with the healthcare provider.

Patient Experience

During the procedure, the patient will be under general anesthesia and will not feel pain. Postoperatively, patients might experience headaches, soreness at the incision site, and fatigue. Pain is typically managed with medication, and close follow-up care ensures any complications are promptly addressed.
