Loss of guide wire: a lesson learnt review of literature.

Catheterization of central veins is a routine technique which is widely used in emergency department and medical intensive care units. Seldinger's technique is widely used to place central venous and arterial catheters and is generally considered safe. The technique does have multiple potential risks. Guide wire-related complications are rare but potentially serious. We describe a case of a lost guide wire during central venous catheter (CVC) insertion followed by a review of the literature of 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.
