What is subclavian vein cannulation?
Percutaneous cannulation of the subclavian vein uses anatomic landmarks to guide venipuncture and a Seldinger technique to thread a central venous catheter through the subclavian vein and into the superior vena cava.
Why do we Cannulate the right subclavian vein?
Right subclavian cannulation, versus left, is sometimes preferred because it avoids the thoracic duct and because the right pleural apex is lower than the left.
Does the subclavian vein turn into the axillary vein?
The axillary vein terminates by becoming continuous with the subclavian vein at the lateral border of the first rib 2.
What is right subclavian vein?
The right subclavian vein is joined by the right lymphatic duct at the right venous angle, which drains lymph from the right upper quadrant of the body (right side of the head, neck, thorax, right upper extremity).
Why subclavian vein is used for catheterization?
Subclavian catheterization also carries a lower risk of catheter-related infection and thrombosis than femoral or internal jugular vein catheterization. Since Aubaniac’s original description in 1952,4 subclavian vein catheterization via the infraclavicular approach has become a well-established technique.
When does subclavian become axillary?
11.1. 6 Termination. The subclavian artery extends to the outer border of the first rib, where it becomes the axillary artery.
Where does subclavian vein drain into?
Blood Supply and Lymphatics The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).
Which vein is used in neck for CVC?
A central venous catheter (CVC) is an indwelling device that is peripherally inserted into a large, central vein (most commonly the internal jugular, subclavian, or femoral), and advanced until the terminal lumen resides within the inferior vena cava, superior vena cava, or right atrium.
Where does the subclavian vein join the axillary vein?
The subclavian vein is the continuation of the axillary vein as it courses beneath the clavicle. It travels superiorly starting at the lateral border of the first rib, then under the clavicle medially until it joins the internal jugular vein.
Which approach to the subclavian vein is preferred for intramuscular cannulation?
An infraclavicular approach to the subclavian vein is preferred by the authors. The operator stands on the side to be cannulated.
What should I do if the subclavian artery is errantly cannulated?
If the subclavian artery is errantly cannulated by either the tissue dilator or the CVC, leave the dilator or catheter in place and obtain surgical consultation for possible surgical removal.
Why is the subclavian vein not used for shunt catheters?
* The subclavian vein may be less preferred for stiff catheters (because of difficulty achieving the sharp turn into the superior van cava) or large-bore hemodialysis catheters (which can cause venous stenosis that renders the ipsilateral arm unsuitable for arteriovenous shunt placement).
