Hi, The last time I went in for Angioplasty I was looking forward to having the entry site in my arm rather than thigh. However, upon arrival they said that anyone who has had a bypass, cannot have entry made through the arm. I am very intrigued as to why because the Cardiologist didn't give me an answer, he just kept saying "you can't". Surely if you know the bypass map then there isn't a problem, and don't you go in through the Aorta anyway? then into the coronary arteries? I can't see how your could accidentally go through a bypass vessel, so there must be another reason. The only thing I can think of, is they might assume I've had arteries removed from my arms for grafting, but they could easily see I haven't, there are no scars.
