Vascular terror: the strange nightmare of a knotted guidewire during central venous catheterisation.

A 79-year-old woman presents to the hospital with dyspnoea, fever, and hypotension, and is diagnosed with community-acquired pneumonia and septic shock. Resuscitation is initiated with fluids and vasopressors, and a central venous catheter is placed. However, during the procedure, the guide experiences resistance and cannot be removed, becoming trapped. This is confirmed with tomography and reconstruction, demonstrating intravascular position. The patient is then sent to interventional cardiology for extraction, which is successfully performed using the EN Snare (Merit Medical). The significance of this case lies in the complications of not guiding procedures with ultrasound and how to resolve them, such as the guide being trapped in this patient.
