Hi JeepNerd,
You know as an Analyst, I am always interested in studies and particularly studies with high volume looking at the design, measurements and sample size to validate a conclusion. This particular study was low volume with limitations as noted in the Abstract.
Statistics class 101 speaks to the lowest number range to have validated conclusion and this study is too small and has too many limitations for a validated conclusive outcome for all.
Some of the limitations of the study which they mention in the abstract are; one institution and as quoted in the study, "several limitations of the study must be noted" and "the sample size of the present study is small and the study design is retrospective." I also noticed that other medical conditions were included in addition to Moyamoya and there was no mention of lifestyle choices by the individuals studied or co-morbid conditions specific to the individuals studied.
However, the conclusion of the study, albeit small and including only one institution, said "The present data suggests that surgery may be of benefit in patients with Moyamoya disease despite the risks of ischemic complications if diagnosed early." Unfortunately, many are not diagnosed early due to the lack of knowledge of Moyamoya in the medical community. Clearly, my brother is one of those not diagnosed early (misdiagnosed for 4 years). In that time, he had two strokes, a dissected right upper internal carotid artery (his artery lays in his neck like a soaked roll of paper towel) and a hemorrhage and his left side blocked to a point time was against him in terms of being completly blocked to blood flowing in reverse if he didn't die first. Clearly, one cannot survive with blood flow in reverse or both carotid arteries completely blocked and one actually dissected. My brother also had aphasia. After his surgery, the aphasia diminshed to a point the ICU nurses called the doctor because they had an aphasia notice and when my brother was speaking to them with no problem you can only imagine their confusion and my amazement. I should add that my brother is 3 years and almost 3 months post surgery and is doing extremely well with no complications or any indication of complications to date.
The re-vascularization surgery puts the Moyamoya patient on a level playing ground meaning they stand the chance of having a stroke the same as any other person depending on a number of factors such as physical, genetic makeup, co-morbid conditions and lifestyle choices.
As an example, I don't have Moyamoya. We come from a family with a history of heart attacks and strokes and my brother having Moyamoya. Genetically, I am at risk for a stroke even without having Moyamoya. Added to the genetic part, my lifestyle choices can also play a big part in my risk for a stroke (If I don't exercise, eat properly or if I drink to excess or smoke, I would most likely be a stroke waiting to happen) as well as any co-morbid conditions that may exist.
In my opinion, seriously, I'd prefer to have blood flow. Even if my brother had been diagnosed early, In retrospect, knowing what I know today about Moyamoya and Moyamoya being a progressive disease, I'd opt for the bypass. However, it is a personal choice to have surgery or not but personally I can't imagine not having the surgery. It goes without saying that a progressive disease that narrows and closes the carotid arteries is a stroke, hemorrhage or death waiting to happen. Is the progression slower or faster depending on the individual? Regardless, ultimately something will occur with little to no blood flow and one can't survive very long under those conditions and especially if blood flow goes in reverse.
Just my observations as I am not a doctor but clearly, simple logic and common sense tells me that a progressive disease is just that......progressive and to wait is, in the case of Moyamoya disease, a stroke hemorrhage or death waiting to occur.
