[A lost Seldinger technique guide wire as the cause of deep venous thrombosis]

Five months after the initial abdominal surgery, a female patient presented with a deep venous thrombosis of the right leg. A guide wire, lost during perisurgical insertion of a central venous catheter using Seldinger's technique, was identified and surgically removed. The guide wire had previously remained undetected despite regular radiological controls. The article presents details of the case together with a review of the literature regarding potential complications of Seldinger's technique. Common reasons and possible options for preventive and therapeutic strategies will be discussed.
