What is a venous access port?

venous access ports are medical appliances that can be inserted under the skin during a small surgery. These devices are used to supply drugs and other substances directly to the human circulatory system, especially under circumstances where such treatment is regularly required. After the initial procedure, it is usually less painful and invasive insert the needle into the venous access port than directly into the vein. This is due to the fact that the ports are located directly under the skin. These ports can be associated with the main veins such as Jugular, Subclavian and superior vena Cava, and can usually resist several hundred needle before replacement.

To describe venous access ports, a number of different expressions can be used. These medical appliances are sometimes called portacaths, which is the result of a combined port and catheter. This is due to the fact that each of these applications are formed by a catheter that connects to the vein, and a silicone port that can be pierced by a needle. Term "completely implanted port" (tIP) also used to distinguish these devices from other venous access methods such as peripherally inserted central catheter lines (PICC).

The two main components of the venous access port are a catheter and a small port, which is filled with a silicone material to be modified separately. These devices are installed under the skin in surgery, during which the catheter is inserted into a suitable vein, such as jugular. The silicone filled with the port is then fastened to the skin and the cut is closed. Once the venous access port is installed, it is possible to insert the needle through the skin into the silicone of the filled port and either inject the medicine or draw blood. After removing the silicone Will needle, it tends to close naturally, even if anticoagulants are sometimes injected to prevent clotting.

There are several different reasons for installing a venous access port, all of which are related toby medical treatments. One of the reasons is that some people have problems with their veins, which makes it difficult or impossible to insert a needle every time a medicine is needed or blood is needed. Some medical treatments may also damage the veins, in which case a venous access port may be installed in advance. These ports are also useful for patients who require repeated intravenous therapies in the long run, need regular blood transfusions or undergo treatment such as bone marrow transplantation.
