Moyamoya Disease: Anesthesia Management Review
Moyamoya Disease: Anesthesia Management Review Moyamoya disease is a rare condition that affects blood flow in the brain. It happens when the main blood vessels in the brain get blocked. This leads to the growth of new, weak blood vessels. These vessels are fragile and can easily get blocked too.
This makes surgery tricky. We need to be very careful with anesthesia for moyamoya patients. Our review looks at moyamoya disease anesthesia protocols. It focuses on how to care for moyamoya patients during surgery.
It’s important to know the risks of moyamoya surgery. We’ll cover the risks and steps to take to keep patients safe.
Understanding Moyamoya Disease
Moyamoya disease comes from a Japanese term meaning “hazy puff of smoke.” It’s a condition where blood vessels form in a special way. This happens because arteries at the base of the brain are blocked. It leads to different symptoms.
Definition and Symptoms
Moyamoya syndrome means the arteries at the brain’s base get blocked over time. It can cause many symptoms. These include short-term brain attacks, strokes, seizures, and thinking problems.
Children often have more brain strokes from moyamoya. Adults might have bleeding strokes instead.

Being exposed to radiation can also play a part in getting moyamoya.
| Symptom | Description | Age Group |
|---|---|---|
| Transient Ischemic Attacks | Brief episodes of neurologic dysfunction caused by ischemia without acute infarction. | Children |
| Strokes | Interruption of blood supply to the brain leading to chronic or severe neurologic damage. | Both children and adults |
| Seizures | Sudden, uncontrollable electrical disturbances in the brain leading to various physical and sensory symptoms. | Children |
| Cognitive Decline | Notable and progressive deterioration in cognitive abilities, including memory and thinking skills. | Adults |
Understanding moyamoya disease helps us find better ways to treat it. This is key for managing this complex condition.
Diagnosis of Moyamoya Disease
Doctors use special imaging to find moyamoya disease. This helps them see the brain’s blood vessels clearly. They use different tools to check how bad the disease is.
Imaging Techniques
Diagnostic imaging for moyamoya includes several important methods:
- Magnetic Resonance Angiography (MRA): This test doesn’t need surgery. It shows the blocked blood vessels and new paths in the brain.
- Digital Subtraction Angiography (DSA): This is the top choice for seeing blood vessels. It shows moyamoya disease clearly.
- Computerized Tomography (CT): CT scans are not as detailed but can spot blood vessel problems and bleeding.
Laboratory Tests
No blood test can say for sure if someone has moyamoya disease. But, blood tests help rule out other health issues. They also help doctors decide on treatment. Genetic tests are useful for families with moyamoya, making diagnosis more accurate.
