The port is usually inserted in the upper chest (known as a "chest port"), just below the clavicle or collar bone, with the catheter inserted into the jugular vein. A port consists of a reservoir compartment (the portal) that has a silicone bubble for needle insertion (the septum), with an attached plastic tube (the catheter).
Surgically implanted infusion ports are placed below the clavicle (infraclavicular fossa), with the catheter threaded into the heart (right atrium) through a large vein. Once implanted, the port is accessed via noncoring "Huber" needles inserted through the skin. The health care provider may need to use topical anesthetic before accessing the port.
The catheter is a foreign body in the vein and often provokes an inflammatory reaction in the vein wall. This results in scarring and narrowing of the vein, often to the point of occlusion. This can cause problems with severe venous congestion in the area drained by the vein and may also render the vein, and the veins drained by it, useless for ...
A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein. A Hickman line is a central venous catheter most often used for the administration of chemotherapy or other medications, as well as for the withdrawal of blood for analysis.
Surgically implanted infusion ports are placed below the clavicle (infraclavicular fossa), with the catheter threaded into the heart (right atrium) through a large vein. Once implanted, the port is accessed via a "gripper" non-coring Huber-tipped needle (PowerLoc is one brand, common sizes are 0.75 and 1 inch (19 and 25 mm) length; 19 and 20 gauge.
The jugular vein is prominent in heart failure. When the patient is sitting or in a semirecumbent position, the height of the jugular veins and their pulsations provides an estimate of the central venous pressure and gives important information about whether the heart is keeping up with the demands on it or is failing.

A peripheral venous catheter is usually placed in a vein on the hand or arm. It should be distinguished from a central venous catheter which is inserted in a central vein (usually in the internal jugular vein of the neck or the subclavian vein of the chest), or an arterial catheter which can be placed in a peripheral or central artery.
Catheter placement in one of the big veins (Subclavian vein, Internal jugular vein or femoral vein) is routinely done to monitor central venous pressure (CVP), to administer long term intravenous medication and parenteral nutrition in critically sick patients. The subclavian vein is the preferred choice for this purpose because it is most ...
