Translation of "central line" into Japanese

In medicine, a central venous catheter ("central line", "CVC", "central venous line" or "central venous access catheter") is a catheter placed into a large vein in the neck (internal jugular vein), chest (subclavian vein or axillary vein) or groin (femoral vein); it is used to administer medication or fluids, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure.
