Early transection of a central venous catheter in a sedated ICU patient.

We report transection and embolization to the heart of a subclavian venous catheter in an immobilized and mechanical ventilated patient. The catheter tip was retrieved using a percutaneous method via the left femoral vein. Mechanical compression of the subclavian venous catheter at the costoclavicular area is termed pinch-off syndrome. It can be recognized by intermittent difficulties with drug injection, and chest wall swelling at the insertion site. The diagnosis can be confirmed by chest radiography with or without contrast administration. A more lateral approach of the subclavian vein is advocated to prevent compression.
