Cerebrovascular Neurosurgery

Building Your Care Team and Preparing for Consultation

At a Glance

The best preparation for a Moyamoya consultation is to choose a specialized cerebrovascular team, bring your catheter angiogram, MRI/MRA, and perfusion images, document symptoms and medicines, and obtain a written plan for hydration, blood pressure, and aspirin.

Because Moyamoya is a rare and complex condition, your choice of medical team is one of the most important decisions you will make. This requires a coordinated group of specialists who understand how to protect the brain before, during, and long after surgery [1][2].

The Multidisciplinary Care Team

A high-quality Moyamoya program is usually found at a specialized cerebrovascular center. Your “core team” should include:

  • Cerebrovascular Neurosurgeon: This is the specialist who performs the revascularization surgery. They must have specific, documented experience in microvascular bypass techniques [3][4].
  • Stroke Neurologist (Vascular Neurologist): These doctors specialize in the medical management of blood flow and stroke prevention. In children, this should be a Pediatric Neurologist with stroke expertise [1][5].
  • Neuropsychologist: Because Moyamoya can affect executive function and memory, a neuropsychologist provides a baseline assessment to track your cognitive health over time [6][7].
  • Neuro-Anesthesiologist: Surgery for Moyamoya requires extremely precise control of blood pressure, carbon dioxide, and hydration. An anesthesiologist who works on Moyamoya cases is vital for a safe operation [8][2].
  • Geneticist & Other Specialists: If you have Moyamoya Syndrome, you may also need a hematologist (for sickle cell), an endocrinologist (for autoimmune thyroid disease), or a specialist in Down syndrome to ensure your underlying condition is managed simultaneously [9][10].

Vetting Your Surgeon

Don’t be afraid to ask direct questions. A surgeon who is an expert in this field will welcome the opportunity to discuss their experience. You are looking for a surgeon who performs these surgeries regularly and has an experienced team [3].

Key questions to ask include:

  1. “What is your center’s recent case volume by age group and procedure, and what are your audited complication and bypass patency rates?”
  2. “Do you perform both direct and indirect bypasses?” An expert should be able to explain why one is better for your specific anatomy [11].
  3. “What is your protocol for preventing strokes and managing hyperperfusion during and after surgery?” Experienced centers typically have established protocols for nursing and ICU staff to spot Moyamoya-specific concerns [12][13].

Preparing for Your First Consultation

The first visit is often a deep dive into your imaging. To make the most of this time, you must arrive with your complete medical history. Do not rely on the hospital to send over your records; bring your own copies.

  • Imaging on Disc: Bring the actual digital images (DICOM files) of your Catheter Angiogram (DSA), MRI/MRA, and any Perfusion scans (like SPECT or PET) [14][15]. The surgeon needs to see the raw images.
  • Symptom Timeline: Keep a dated log of every TIA, stroke, seizure, or unusual spell [16][15].
  • Medication List: Include dosages of everything you take, especially blood thinners like aspirin or medications for blood pressure [17][18].

Pre-Surgical Optimization and Safety

In the weeks leading up to a consultation or surgery, your team will focus on optimizing your brain’s environment. This usually involves:

  • Hydration: You will be told to maintain normal hydration to keep your blood volume stable [19][20]. The right fluid plan depends on your age, kidney function, and center protocol, so do not attempt “aggressive hydration” without explicit instructions; excessive water can cause fluid overload. Do contact your team for a sick-day plan if you experience fever, vomiting, or diarrhea.
  • Blood Pressure Stability: Your doctors will work to keep your blood pressure in a targeted range [8][21]. Never adjust these medications yourself.
  • Aspirin Management: Aspirin continuation or interruption varies based on your bleeding risk, ischemic risk, and local protocol [20][18]. Do not start, stop, or change aspirin, migraine medicines, or seizure medicines independently; obtain a written perioperative plan from your treating team.

By building a specialized team and arriving prepared, you shift to being an informed manager of your care [22].

Common questions in this guide

How do I choose a medical team for Moyamoya disease?
Look for a specialized cerebrovascular center with a neurosurgeon who regularly performs Moyamoya revascularization and an experienced multidisciplinary team. The team may include vascular neurology, neuropsychology, anesthesia, and specialists who manage associated conditions. Ask about recent case volume and outcomes rather than relying only on general hospital experience.
What should I ask a Moyamoya surgeon before deciding on surgery?
Ask how many patients the center treats by age and procedure, and request audited complication and bypass-patency rates. Ask whether the surgeon performs both direct and indirect bypasses and how the choice fits your anatomy. Also ask how the team prevents strokes and monitors for excessive blood flow after surgery.
What should I bring to my first Moyamoya consultation?
Bring digital copies of the actual images from your catheter angiogram, MRI or MRA, and any brain-perfusion scans such as SPECT or PET. Also bring a dated timeline of transient ischemic attacks, strokes, seizures, or other spells and a complete medication list with doses. Keeping your own copies helps the specialist review the original studies.
Which specialists may be involved in Moyamoya care?
A typical team includes a cerebrovascular neurosurgeon, vascular neurologist, neuropsychologist, and anesthesiologist familiar with Moyamoya surgery. Children may need a pediatric neurologist with stroke expertise. People with associated conditions may also need a geneticist, hematologist for sickle cell disease, endocrinologist for autoimmune thyroid disease, or Down syndrome specialist.
How should I manage hydration, blood pressure, and aspirin before Moyamoya surgery?
Follow a written plan from your treating team rather than changing medicines or fluids on your own. Your plan may address normal hydration, a target blood-pressure range, and whether to continue or pause aspirin based on your individual risks and the center’s protocol. Ask what to do if fever, vomiting, or diarrhea makes it hard to stay hydrated.
How can I coordinate Moyamoya care between a specialty center and local doctors?
Ask the specialty center to identify the neurologists and other clinicians who will manage long-term care and to explain how information will be shared with your local team. Request written instructions for medicines, fluids, blood pressure, and sick days. Clear roles and communication can help prevent conflicting advice.
