[|Human|] Dear SirMy wife is suffering from Narrowing of Brain Arteries and the have done MRI reports which suggests severe narrowing of brain arteries, now the doctor has suggested DSA (Digital Subtraction Angiogram) of Brain to check the further status of the disease , pls suggest is there any risk involved in going for DSA test.Further the doctor has said we will need to do a bypass surgery of brain which may help the blood flow from any other donor artery , pls also revert if bypass of brain is suggested and what are percent chances of this bypass going sucessful and what are the effects after the bypass operation.
[|AI|]  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 wives case, so that the definitive treatment plan can be made. There are several possibilities in your wives case. The most common can be a disease called as 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 autoimmune 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, Chat Doctor. Ly/
