Vein Access Technologies: STEM anatomy
See the video dissection of the AC region above.
This is an actual dissection of the antecubital region for STEM venipuncture - whether it is for a blood draw, an IV, an injection of contrast, a blood donation, a plasma donation, or a Factor VIII injection.
Pay attention to the detail: the skin, the subcutaneous tissue, the position of the veins within those tissues, the actual vein itself, and the anatomical surgical landmarks for the field under consideration.
