Is Laser treatment really worth it?

It's great to see the technology developing and I am all for it, but it seems that certain technologies may not be necessary until they are fully or futher developed. I can see the points in this article that the laser technology helps with doing a bypass in the brain and fully agree that brain surgery is no easy task at anytime. What I don't see is if it is worth it. Brain surgery is brain surgery. The risk of it is rediculous everytime, but is improving from 15% chance to 12% chance of suffering a stroke worth the cost and risk of a fairly new procedure. I can see both sides. The cost of the laser surgery is going to be a lot more expensive, but what is a couple more hundred thousand when it has to do with you life? And 3% can make the difference between life and death, its better than 0%. Although how much has this technique been tested? How does the brain react by being bombarded with a high intensity wave of light energy? Does it give of radiation that may cause surrounding cells to be cancerous? The article seemed to go only one way, and that's for it. And it was effective in persuading the reader to be for it. By tapping into the emotional aspect of the reader to feel for the man getting the operation. He's young, seems to have a steady job he enjoys doing, and a family. You feel for people in the prime of their life. Then the details the writer gives is almost too much. Being from a science background, a lot of us understand most of the readings, but in this case most of it was over-the-top in detail to which the writer lost me.

He explains the bypass that needs to occur "create a detour for blood to flow by taking a vein from the leg and sewing its ends to the artery on either side of the aneurysm". This was good enough. But he then goes into the details of the operation, listing terms, "the bypass would run fromt he carotid atery in the neck... down through the Sylvian fissure between the frontal and temporal lobes". What? I understand the idea but I don't feel it was necessary to go over it fully. Its not like we're the ones doing the operation, and I don't feel its really necessary to put in to persuade us to be for it or not. O well, it was an interesting read none-the-less. Times up.
