I asked him, he drew a hole and explain to me that if plaque is build up inside of it then he will have to put a stent and if it is outside then he would send me home. That was it. I started asking my 2nd question and he said :I will explain it later" and went to his cubicle. Next thing i am being sedated. He is "that kind" of surgeon. I would never recommend him even to my worst enemy (which I don't have).
