The image displays a recently inserted temporary dual-lumen hemodialysis catheter positioned in the left internal jugular vein of a patient. This type of central venous access device serves as a crucial but temporary vascular access option for patients requiring urgent or short-term hemodialysis treatment. The catheter features two color-coded lumens—red for arterial (blood withdrawal) and blue for venous (blood return)—that facilitate the extracorporeal blood circuit necessary for dialysis.
