A few months ago someone posted pictures of their port. I couldn't find them although I did find the post from abloedel.
This is what I found on google.....
What is a Port-a-cath?
A Port-a-cath is a long hallow tube with a reservoir attached to the end called a portal. The long hollow tube is commonly referred to as a central venous catheter, because it is inserted through the chest into a large vein leading directly into the heart. The catheter is tunnelled under the skin before entering the large vein; this is done to form a physical barrier against bacteria entering the line and blood stream. The portal is positioned under the fatty layer of skin under the chest wall and stitched in place, then the portal is used to access the catheter for an infusion line (drip) or syringe, using a specially designed needle.
Why use a Port-a-cath?
A Port-a-cath can be left in for a substantial number of months, possibly years, if well looked after.
Having a Port-a-cath will make it more comfortable for you because you will not have to endure a cannula being inserted into a vein over and over again.
Port-a-caths are used for people with poor veins, and who require regular drug injections, infusions, blood transfusions or long term nutrition, over a long period of time.
The advantages of a Port-a-cath over other central venous devices are that:
a) the risk of infection of the catheter is reduced
b) cosmetically the Port-a-cath is more acceptable
c) the catheter does not need flushing with heparin solution (to prevent blockage of the catheter) quite so often
