Healthcare professionals require central venous access (access to a major vein) for several reasons, including the administration of medications, the insertion of catheters and the frequent drawing of blood. There are many devices that can be used to enable ongoing central venous access, known as Central Venous Access Devices (CVADs). The most suitable device is determined based on the patient’s condition and the healthcare professional’s requirements.
Types of Central Venous Access Device
Infus-a-port is an implanted CVAD that sits beneath the skin. This device is suitable for long-term use (more than one year) and is frequently required for the administration of chemotherapy in cancer patients. It is accessed through the skin using a special needle when treatment is needed, and is not visible or felt when not in use.
Hickman catheter is a tunnelled CVAD that is suitable for shorter-term central venous access. Unlike the Infus-a-port, the Hickman line exits through the skin and can be used without a needle, making it practical for patients who require frequent blood draws or medication administration.
All central venous access devices are inserted under imaging guidance to ensure accurate placement and minimise the risk of complications. Dr Garbowski and the team at Perth Vascular Clinic are experienced in the full range of CVAD insertion procedures.
