Purpose: The subclavian vein is thought to be the most appropriate route for central venous access in major maxillofacial surgery. Evidence suggests that left-sided central venous catheters should lie below the carina and be angulated at less than 40 degrees to superior vena cava wall. This reduces perforation risk. With ...

BACKGROUND: The internal jugular vein (IJV) is one of the recommended sites for safe insertion of a central venous catheter (CVC). Although CVC insertion via the IJV has a lower risk of severe complications such as pneumothorax and arterial bleeding than insertion via the subclavian vein, few reports have provided ...
