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).
Once access to the jugular vein is confirmed, a guidewire and introducer sheath are typically placed to facilitate the shunt's placement. This enables the interventional radiologist to gain access to the patient's hepatic vein by traveling from the superior vena cava into the inferior vena cava and finally the hepatic vein.
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. [4]
A central venous catheter (CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein. It is a form of venous access. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged ...
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
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 anterior jugular vein varies considerably in size, bearing usually an inverse proportion to the external jugular. [1] Most frequently, there are two anterior jugulars, a right and left. [1] [4] However, there is sometimes only one. [1] A duplicate anterior jugular vein may be present on one side, which may cross over the midline.
It is a long tube with a one-way valve running subcutaneously from the peritoneum to the internal jugular vein in the neck, which allows ascitic fluid to pass directly into the systemic circulation. Various models exist, among which the LeVeen shunt and the Denver shunt. [2] Possible complications include: Infection; Superior vena caval thrombosis
