What is placement of a central venous infusion catheter with an external lumen?
Placement of a central venous infusion catheter with an external lumen is a procedure for putting a catheter into the subclavian vein. The subclavian vein is a large vein in the upper part of the chest under the collarbone. The catheter is a thin, soft plastic tube. One end of the catheter is passed through the wall of the vein and advanced to a place just above the heart. The outside end of the catheter is used to draw blood or to give you intravenous (IV) medicine.
