[Damage of the subclavian vein with a thorax drainage].

The necessity for insertion of a thorax drainage can lead to serious complications. Especially the use of a trocar instead of a mini-thoracotomy has a notable risk of misplacement or complications. Chest tubes per se can perforate the parietal pleura resulting in an extrathoracic position of the tube and contraindications for chest tubes should always be considered. Accidental lacerations of blood vessels should be avoided by a correct technique and a clear indication. A chest X-ray in one plane is not sufficient to prove correct positioning of a chest tube and suspected misplacement of a chest tube has to be assessed radiographically in at least two planes. A case of a fatal complication of a misplaced chest tube causing a laceration of the right subclavian vein is described.
