Hi Amy,
I understand that you have received much of your information from "here say" but at least you are doing your best to find out more about this "rare" disease. As for doctors diagnosing MM, they do NOT have to see a patient's angiogram results to make this diagnosis.
I was diagnosed based on my MRI/MRA results. I believe medical professionals who are familiar and experienced with this disease are able to appropriately make this diagnosis based on their experience, education, and research of this disease. As for MM experts, I believe it all depends on who you speak to.
All of us who have successfully had surgery, whether a bypass or EDAS, will attest to their own medical professional's expertise. And why wouldn't we? They literally saved our lives! ;
When people come to me and ask me for my opinion or advice, I don't try to steer them in one direction and try to convince them to make the travel to North Carolina as I did--to my neurosurgeon. I share my story and personal situation.
I do; however,
press upon them the importance to seek the opinions of MM experts and tell them to make their decision from there. I also understand that we all have other things to consider such as finances, family, etc., which may prevent someone from traveling across the country... I do have to admit that I firmly believe in what I was told by my neurologist...
"it's important and worth it to have it done right, the first time"
as he sees many MM patients who have received surgery from various surgeons, including those who are considered by "MM experts" and who have had to return for additional surgeries

Sometimes things happen...we are all individual cases.
You mentioned your dr. being old...and him saying surgery wouldn't work on you. Again, I would recommend you seeking additional opinions, and soon.

Remember,
you DON'T need to have an angiogram to be diagnosed. If you have MRI or MRA films, that should be sufficient (to obtain opinions and be properly diagnosed). Call the offices of the neurosurgeons you are interested in, and they will provide you with additional information. ;

Take care,
Shan
