The tip of the catheter can also be misdirected into the contralateral ( opposite side ) subclavian vein in the neck, rather than into the superior vena cava.
32.
The right and left vertebral veins drain the vertebrae and muscles into the right subclavian vein and into the superior vena cava, into the right atrium of the heart.
33.
The blood does not come into direct contact with the parenchymal lymphatic ducts, which drain into one of the two subclavian veins, near their junction with the internal jugular veins.
34.
Additionally, studies suggest that short term use of CVCs in the subclavian vein is less likely to be associated with blood clots than CVCs placed in the femoral vein in non-cancer patients.
35.
Temporary internal pacemakers can work, but a wire must be threaded through the jugular vein in the neck or the subclavian vein under the collarbone all the way into the right ventricle.
36.
Short-chain fatty acids and medium-chain fatty acids are primarily absorbed through the portal vein during lipid digestion, while long-chain fatty acids are packed into chylomicrons and enter lymphatic capillaries, and enter the blood first at the subclavian vein.
37.
The right bronchomediastinal trunk may join the right lymphatic duct, and the left the thoracic duct, but more frequently they open independently of these ducts into the junction of the internal jugular and subclavian veins of their own side.
38.
In its course it crosses the sternocleidomastoideus obliquely, and in the subclavian triangle perforates the deep fascia, and ends in the subclavian vein lateral to or in front of the scalenus anterior, piercing the roof of the posterior triangle.
39.
The subclavian vein lies behind the clavicle, and is not usually seen in this space; but in some cases it rises as high as the artery, and has even been seen to pass with that vessel behind the Scalenus anterior.
40.
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.
