Dr. Claude Édouard Chatillon

Dr. Claude Édouard Chatillon surgically treats a wide range of neurological conditions, including:

Functional Neurosurgery & Neuropathic Pain Conditions

• Spasticity (severe, for Baclofen pump or selective dorsal rhizotomy consideration): Severe muscle stiffness and spasms, potentially managed with implantable drug delivery systems or nerve root surgery.
• Medically Refractory Epilepsy (for surgical evaluation): Epilepsy that continues despite trials of multiple anti-seizure medications, prompting consideration for surgical interventions.
• Trigeminal Neuralgia: A chronic pain condition affecting the trigeminal nerve, causing severe facial pain, potentially treated with microvascular decompression.

Cerebrovascular Disorders (Requiring Surgical Intervention)

• Cavernous Malformations (Cavernomas): Clusters of abnormal, dilated blood vessels that can occur in the brain or spinal cord and may cause bleeding or seizures.
• Cerebral Aneurysms (Unruptured & Ruptured): A bulge or ballooning in a blood vessel in the brain, which can leak or rupture, causing a hemorrhagic stroke.
• Subarachnoid Hemorrhage (SAH): Bleeding into the space between the brain and the surrounding membrane, often caused by a ruptured aneurysm.

Spinal Column & Spinal Cord Disorders

• Spinal Stenosis (Cervical, Lumbar): Narrowing of the spinal canal, which can put pressure on the spinal cord and nerves.
• Syringomyelia (Syrinx): Formation of a fluid-filled cyst (syrinx) within the spinal cord, which can expand and damage nerve tissue.
• Herniated Disc (Cervical, Thoracic, Lumbar): A condition where the soft inner portion of an intervertebral disc protrudes through the outer ring, potentially compressing nerves.

This list is not exhaustive. For personalized advice regarding your specific neurosurgical condition, please consult with Dr. Claude Édouard Chatillon.

• Syrinx (Syringomyelia) Decompression Surgery: Procedures to drain or shunt fluid-filled cavities (syrinxes) within the spinal cord.
• Spinal Fusion & Instrumentation (Cervical, Thoracic, Lumbar): Surgical stabilization of the spine using bone grafts and/or metallic hardware for conditions like instability, deformity, or after trauma/tumor resection.
• Cerebral Aneurysm Clipping & Coiling (Endovascular coiling often with Interventional Neuroradiology): Surgical or endovascular treatment to secure brain aneurysms and prevent rupture or re-rupture.
• Surgery for Degenerative Spine Disease (e.g., Herniated Discs, Spinal Stenosis): Procedures such as microdiscectomy, laminectomy, and foraminotomy to relieve nerve compression and pain.
• Interpretation of Advanced Neuroimaging (MRI, CT, Angiography, Myelography): Expert analysis of specialized imaging of the brain, spinal cord, and vasculature to guide diagnosis and surgical decision-making.
• Arteriovenous Malformation (AVM) & Dural Fistula Treatment (Surgical Resection, Embolization, Radiosurgery Coordination): Multimodal approaches to treat abnormal connections between arteries and veins in the brain or spinal cord.
• Non-Operative Management of Select Neurosurgical Conditions: Providing conservative management options when surgery is not immediately indicated, including observation, medication management referrals, and pain management strategies.

Note: This list provides a general overview. Neurosurgical treatment plans are highly individualized. Discuss with Dr. Chatillon for care relevant to your specific condition.

Are consultations and neurosurgical procedures with Dr. Chatillon, a Neurosurgeon, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations with a licensed Neurosurgeon like Dr. Chatillon, as well as most diagnostic imaging reviews and provincially insured neurosurgical procedures (e.g., for tumors, spine conditions, aneurysms), are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC when a referral from a family doctor or another specialist is in place. Some advanced technologies, specific implantable devices, or purely elective/cosmetic procedures may have different coverage. It's crucial to discuss coverage specifics with Dr. Chatillon's office, the hospital's financial services, or Régie de l'assurance maladie du Québec (RAMQ) prior to any major procedure.

Do I need a referral to see Dr. Chatillon, a Neurosurgeon?

Yes, a referral from your family physician, an emergency room physician, or another specialist (like a neurologist or oncologist) is almost always required to see a Neurosurgeon such as Dr. Chatillon. Neurosurgical conditions are typically complex and require initial assessment and investigation before a neurosurgical consultation is appropriate. The referral ensures coordinated care and that you are directed to the right specialist.

What is recovery like after neurosurgery?

Recovery from neurosurgery varies greatly depending on the type and complexity of the surgery, the underlying condition being treated, and the individual patient's overall health. It can range from a few weeks for some minimally invasive spine procedures to several months or longer for major brain or complex spine surgeries. Recovery often involves a hospital stay, followed by a period of rest and rehabilitation, which may include physical, occupational, or speech therapy. Dr. Chatillon and the care team will provide detailed post-operative instructions and support throughout the recovery process.

Does Dr. Chatillon perform minimally invasive neurosurgery?

Many neurosurgeons, including potentially Dr. Chatillon, utilize minimally invasive surgical (MIS) techniques when appropriate for the patient's condition. These techniques involve smaller incisions, specialized instruments, and often advanced imaging guidance, which can lead to reduced pain, shorter hospital stays, and faster recovery compared to traditional open surgery. You should ask Dr. Chatillon if minimally invasive options are suitable for your specific neurosurgical needs.

What are the general risks associated with neurosurgery?

All surgical procedures carry some risks. For neurosurgery, these can include infection, bleeding, blood clots, adverse reactions to anesthesia, and neurological deficits (such as weakness, numbness, or problems with speech or vision), depending on the area being operated on. There's also the risk that the surgery may not fully alleviate the symptoms or that the underlying condition may recur. Dr. Chatillon will discuss the specific risks and potential benefits of your proposed surgery in detail, allowing you to make an informed decision.

When might someone need to see a Neurosurgeon?

A referral to a Neurosurgeon like Dr. Chatillon is typically made by another physician when a condition is suspected or diagnosed that may require surgical intervention or specialized neurosurgical assessment. This can include brain tumors, spinal disc herniations causing severe nerve compression, spinal stenosis, traumatic brain or spine injuries, cerebral aneurysms, arteriovenous malformations (AVMs), hydrocephalus, some forms of epilepsy, or peripheral nerve entrapment syndromes not responding to conservative treatment.

What are some common procedures a Neurosurgeon performs?

Neurosurgeons perform a wide variety of intricate procedures. Common surgeries include craniotomies (opening the skull) for brain tumor removal, aneurysm clipping, or hematoma evacuation; spinal surgeries like laminectomies or discectomies for nerve decompression, and spinal fusions for instability; and placement of shunts for hydrocephalus. Dr. Chatillon would be able to discuss specific procedures relevant to your condition. Many neurosurgeons also have subspecialty interests, such as pediatric neurosurgery, spine surgery, or vascular neurosurgery.
