Expert Care for Moyamoya

Moyamoya is a rare, progressive condition that narrows the arteries at the base of the brain, reducing blood flow and raising your risk of stroke. It can affect both children and adults – and early, expert intervention matters.

The Cerebrovascular Center at Swedish Cherry Hill is a leader in treating conditions that affect the blood vessels in the brain, and the center is part of one of the largest neuroscience institutes in the country.

Moyamoya Treatment Options

Your care team will recommend the best approach based on your symptoms, imaging and overall health. Treatments may include: 

Getting an accurate picture of your blood flow is the first step. At the Swedish Cerebrovascular Center, your team may use advanced imaging to confirm your diagnosis and guide treatment, including:

  • MRI and magnetic resonance angiography (MRA)
  • CT scan and CT angiography (CTA)
  • Cerebral angiogram
  • Perfusion imaging to measure blood flow to the brain 

For many people with moyamoya, surgery is the most effective treatment. Our neurosurgeons perform delicate bypass procedures – also called revascularization – that reroute blood flow to restore circulation to your brain.

Medication can't stop moyamoya from progressing, but certain drugs – such as blood thinners and calcium channel blockers – may offer important benefits, alone or alongside surgery.

Your team will assess, monitor and manage your condition over time, which may include regular brain scans so we can act quickly if we identify areas of concern.
