Follow-up chest X-ray after insertion of a port, with a malpositioned tip in the azygos vein. CT scan of the same patient confirming the position of the port tip in the azygos vein. A port is most commonly inserted as an outpatient surgery procedure in a hospital or clinic by an interventional radiologist or surgeon, under moderate sedation ...
An implanted port is less obvious than a tunneled catheter and requires little daily care. It has less impact on a person's activities than a PICC line or a tunneled 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.
An implanted central venous catheter, also called a port a "cath" or "port-a-cath", is similar to a tunneled catheter, but is left entirely under the skin and is accessible via a port. Medicines are injected through the skin into the catheter. Some implanted ports contain a small reservoir that can be refilled in the same way.
The cavoatrial junction (CAJ) is the point at which the superior vena cava meets and melds into the superior wall of the cardiac right atrium. Both the superior and inferior vena cavae enter the right atrium, but only the superior entry is called the cavoatrial junction .
Common site of catheter placement is placed by puncturing the right internal jugular vein (IJV) in the neck, advancing into superior vena cava (SVC) towards the right atrium of the heart due to its straightforward path into the SVC. Alternatively, a SVC catheter can be inserted via the right external jugular vein (EJV) if right IJV is ...
The insertion of a central Groshong line is usually done under local anesthetic by an interventional anaesthesiologist, interventional radiologist or surgeon. Throughout the procedure, ultrasound and X-rays may be used to confirm placement. When a central venous catheter is inserted, a chest radiologic examination is usually performed to ...

Trocars are designed for placement through the chest and abdominal walls during thoracoscopic and laparoscopic surgery, and each trocar functions as a portal for the subsequent insertion of other endoscopic instruments such as grasper, scissors, stapler, electrocautery, suction tip, etc. — hence the more commonly used colloquial jargon "port ...
