Young woman comes into the ER with another episode (3 total events now over the past 6 months) of face drooping, arm weakness, and arm numbness. She was found to have a small stroke. Prior imaging of her neck arteries did not show any blockage but this time the doctors imaged her brain vessels and found that she has blockages of the major arteries of the brain on both sides. She was transferred to our hospital for further evaluation.
After additional work-up, she was found to have moyamoya disease - a condition where there is gradual narrowing and blockage of the large brain vessels that result in strokes and brain bleeding.
The treatment for this just like in the heart in cases of blockage, is to under go a bypass which consists of re routing the blood flow to the brain by connecting a different artery to improve the blood flow.
The patient was observed in the hospital for 3 days after surgery and discharged home. She presented back a couple of months later and had the same surgery performed on the other side.
Over the past 5 years she has not had any recurrent stroke events.
Images show the artery occlusions and surgery.
