I had to take the risk on the first patient I did. He happened to be from Lake Charles, a bus driver who was having what we call TIA’s, transient ischemic attacks. And these attacks would occur in such a way that there wasn’t enough blood going to that part of the brain, and he would get partially paralyzed, temporarily, and have to stop, when he was driving a bus. He finally realized he couldn’t continue doing that. So his doctor sent him over here for us to look at. Not with that idea of doing this, but rather to see if there was anything we could do to help him. And I finally decided that this was the thing to do, and I talked with him about it, and explained to him it had never been done. But I explained to him what was involved, that the operation was a relatively simple technical procedure. And I think maybe because I was from Lake Charles too, he had confidence in what I said, and he submitted to it. Agreed. And it fortunately proved very successful. In fact, he lived 19 years after that, died of a heart attack. Never had any more transient ischemic attacks. So you do have to accept some risk sometimes.
