The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck. This vein runs in the carotid sheath with the common carotid artery and vagus nerve. It begins in the posterior compartment of the jugular foramen, at the base of the skull.
The jugular vein runs parallel to the carotid artery and operates under much lower pressure, returning deoxygenated blood to the heart, whereas the carotid artery, a high-pressure vessel supplying oxygenated blood to the brain, is far more critical and vulnerable in sustaining cerebral circulation.
It is most commonly placed in the neck (internal jugular) but may also be placed in the groin (femoral), liver (transhepatic), chest (subclavian) or back (translumbar). [3] The catheter is inserted into the vessel under ultrasound or fluoroscopic guidance and tunneled through the skin. Tunneled catheters have multiple channels called lumens ...
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 ...
Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
The percutaneous CVC is inserted directly through the skin. The subclavian (left), internal (right) or external jugular, or femoral vein is used. There are several types of central venous catheters; these can be further subdivided by site (where the catheter is inserted into the body) as well as the specific type of catheter used. [39]
"Cardiac catheterization" is a general term for a group of procedures. Access to the heart is obtained through a peripheral artery or vein. Commonly, this includes the radial artery, internal jugular vein, and femoral artery/vein. Each blood vessel has its advantages and disadvantages.
Catheter ablation is usually performed by an electrophysiologist (a specially trained cardiologist) in a cath lab. [citation needed] Catheter ablation procedure involves advancing several flexible catheters into the patient's blood vessels, usually either in the femoral vein, internal jugular vein, or subclavian vein. The catheters are then ...
