Two Cases of Malpositioning of Internal Jugular Central Venous Catheters: A Review of Literature and Current Treatment Recommendations.

Percutaneous central venous catheterization, despite ultrasound guidance, is known to carry significant risks. While central venous catheters are widely used in clinical practice, they are also associated with various complications, including incorrect positioning during insertion. Arterial puncture is a well-recognized complication, and although unintended subclavian or carotid artery cannulation is rare, it can lead to serious consequences. We present two cases, in which a dual-lumen, non-tunneled temporary hemodialysis catheter was inadvertently inserted into the left common carotid artery and in the left innominate vein.
