Venous cutdown is an emergency procedure to secure intravenous access. It is used when peripheral veins are not visualized, commonly due to hypovolemia. The procedure carries with it risks of complications including hematoma, cellulitis, thrombophlebitis, damage to neighbouring neurovasculature and has largely fallen out of favour. However, it may still be used in emergency settings when other options have failed or are unavailable.
