Entrapment of a guide wire: an incidental complication of central line catheter placement

Seldinger's technique is widely used to place central venous and arterial catheters and is generally considered safe. This technique does have multiple potential risks. Guidewire-related complications are rare but potentially serious. We describe a case of an entrapped guidewire during central venous catheter insertion followed by a review of the literature on this topic. Measures which can be taken to prevent such complications are explained in detail as well as recommended steps to remedy errors should they occur.
