The Ivy Sign: A Hidden Clue to Moyamoya Disease

Moyamoya disease is a rare vascular disease that affects the blood vessels in the brain. It can cause serious complications, including stroke. The ivy sign is a radiological finding that is often seen in Moyamoya disease. It is a network of small blood vessels that resembles an ivy plant.

A new study has found that the ivy sign is independently associated with several characteristics of Moyamoya disease, including disease severity, cerebral blood flow, and the risk of stroke. The study also found that the ivy sign is associated with good postoperative collateral formation.

These findings suggest that the ivy sign may be a useful biomarker for Moyamoya disease. This could help improve the diagnosis, treatment, and prognosis of this disease.
