Central Venous Access Port Placement or Removal

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. 

What happens during a Central Port Access procedure?

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.

Learn what to expect and how to prepare for a CVAC.
