Having read through the previous litany of potential disasters and complications, one could ask the obvious question, "Why would anyone want to do this kind of surgery?"

A sound knowledge of the regional anatomy and tutelage by those knowledgeable in particular areas of surgery that may not have been a part of the individual surgeon's prior training is essential. The author was fortunate to have the help of a very accomplished and generous vascular surgeon, Dr. William Abbott of the Massachusetts General Hospital for many months when I began on what I have considered a fascinating and intellectually rewarding odyssey.
