Hi,
Thank you for posting your query.
DSA- digital subtraction
angiography is a safe diagnostic procedure and carries no significant risk. This is important, as it would confirm the diagnosis in your wife's case, so that the definitive treatment plan can be made.
There are several possibilities in your wife's case.
The most common can be a disease called as Moya moya disease, where there is narrowing of main arteries of brain. This condition needs surgery, called as
bypass surgery. This is safe if done by expert neurosurgeons of reputed institutions.
The other likely condition could be
vasculitis, where there is inflammation and narrowing of arteries. This is an auto immune condition and would respond to medical treatment.
Please get back with the DSA report.
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
