[Operative management of penetrating injuries to the subclavian artery. Technical tutorial]

Penetrating injury to the subclavian arteries is one of the most taxing arterial injuries a trauma surgeon can encounter. Operative access for repair is difficult, crossing two separate anatomical areas-superior mediastinum and base of the neck. The artery runs well protected behind sternum and clavicle and tears easily if clamped. Physiologically unstable patients must be rushed to theatre in an attempt to control exanguinating haemorrhage and to repair the injury. In the rare circumastance of being confronted with it, it is imperative for the occasional trauma surgeon to have a practical operative concept for dealing with this type of injury. This tutorial describes a practical approach for penetrating subclavian injuries, and it discusses alternative surgical strategies when supraclavicular expanding hematomas deny straightforward access.
