The cephalic vein : a providential vein

The first time, I saw a Port-à Cath operation, was in 1989. The surgeon did it through the cephalic vein, under local anesthesia. In 1990, I had to do it through the subclavian vein, percutaneously, following the policy of the department, again under local anesthesia. Since 1994, I have been doing this operation, through the cephalic vein. So, I asked myself which technique is better and who should do this operation.
