A Central Venous Access Catheter or CVACs is a tube that is inserted beneath your skin so there is a simple, pain-free way for doctors or nurses to give you nutrients, or to draw your blood.
An interventional radiologist will do the CVAC procedure. You will receive medication to help you relax, and the area will be numbed. A needle is inserted into the skin, creating a small tunnel. The CVAC is then placed in the tunnel with the tip coming to rest in a large vein. You may feel some pressure and slight discomfort during the procedure, but it is not very painful.
