Common Conditions Dr. Jonathan Chainey Addresses

Dr. Jonathan Chainey surgically treats a wide range of neurological conditions, including:

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.
  • Arteriovenous Malformations (AVMs) of the Brain & Spine: Tangles of abnormal blood vessels connecting arteries and veins, which can disrupt normal blood flow and risk rupture.
  • Intracerebral Hemorrhage (ICH - select cases for evacuation): Bleeding within the brain tissue itself, where surgical evacuation may be considered for large or life-threatening hematomas.

Spinal Column & Spinal Cord Disorders

  • Herniated Disc (Cervical, Thoracic, Lumbar): A condition where the soft inner portion of an intervertebral disc protrudes through the outer ring, potentially compressing nerves.
  • Spinal Fractures & Instability (Traumatic or Pathologic): Breaks in the vertebrae or spinal instability often requiring surgical stabilization.
  • Spinal Stenosis (Cervical, Lumbar): Narrowing of the spinal canal, which can put pressure on the spinal cord and nerves.

Functional Neurosurgery & Neuropathic Pain Conditions

  • Chronic Neuropathic Pain (select cases for neurostimulation): Persistent pain due to nerve damage, where spinal cord stimulation or other neuromodulation techniques might be considered.
  • Trigeminal Neuralgia: A chronic pain condition affecting the trigeminal nerve, causing severe facial pain, potentially treated with microvascular decompression.
  • 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.

This list is not exhaustive. For personalized advice regarding your specific neurosurgical condition, please consult with Dr. Jonathan Chainey.

Neurosurgeon Services Offered by Dr. Jonathan Chainey

  • Epilepsy Surgery (e.g., Temporal Lobectomy, Lesionectomy, Corpus Callosotomy - in selected cases): Surgical interventions for medically refractory epilepsy, aimed at removing or disconnecting the seizure focus.
  • Hydrocephalus Management (VP Shunt, ETV - Endoscopic Third Ventriculostomy): Surgical treatment for abnormal accumulation of cerebrospinal fluid in the brain, including shunt placement/revision and endoscopic procedures.
  • Spinal Cord Tumor Resection/Biopsy: Surgical removal or biopsy of tumors located within or around the spinal cord or spinal column.
  • Cavernous Malformation Resection: Surgical removal of abnormal clusters of small blood vessels in the brain or spinal cord that can cause bleeding or seizures.
  • 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.
  • Comprehensive Neurosurgical Consultation & Evaluation: In-depth assessment of conditions affecting the brain, spine, and peripheral nerves, including review of medical history, neurological examination, imaging review, and surgical planning.
