Hey Manny

I'm sorry about your wife's situation but you're at the right place for info.

My foremost suggestion would be to find a neurologist with moyamoya experience to assess your wife. You'll find a list of them here:

It's my understanding that a shunt isn't going to alleviate the blockage caused by moyamoya, bypass surgery is the only way of doing this. Unfortunately until she has the correct surgery, the risk of further strokes is increased. What I've said is not intended to throw you into a panic, but more to get you an informed opinion from an expert. Each and every case of moyamoya is different and there are a number of bypass surgeries depending on the individuals situation.

There does appear to be a general lack of moyamoya knowledge amongst quite a few neurologists who haven't dealt with the disease before. Some form of a blood thinning medication, like Disprin,  is generally given to moyamoya patients. This helps the blood flow through the compromised arteries. I'm not suggesting you self medicate because if your wife is hemorrhaging you really want the blood to thicken, not thin. That's why speaking to a neurologist familiar with moyamoya is imperative.

Unfortunately Asians seem to be more predisposed to moyamoya than Westerners. In my research looking for a surgeon to do my daughters surgeries, it became quite apparent that the Japanese have been dealing with this disease for a very long time and the surgeons over there are very experienced. I came very close to taking Luca to a moyamoya clinic in Japan run by a Dr Touho:

Good luck and stay strong for your wife
