[Rupture of the azygos vein by blunt thoracic trauma. A case report and literature review].
Blunt chest trauma is a common injury in traffic accidents. Thoracic vessel trauma frequently affects intercostal arteries, the aorta and less often the subclavian artery. Azygos vein injury is uncommon and has previously been described in only 19 cases. The 20th case of blunt azygos vein injury due to high energy trauma as a consequence of a traffic accident is reported with a review of the literature. Preoperative diagnosis was performed by computed tomography. Azygos vein injury is rare but potentially lethal (8/20, 40.0%). Chest radiograph with right hemothorax is reported consistently except for two cases. Fractures of ribs and/or thoracic spine (T3-5) were found in nine patients, while neither were found in 11/20 cases. Pathognomonic signs have not been described in the literature. Early resuscitation and immediate thoracotomy with recognition and treatment of azygos vein rupture is necessary to avoid a fatal outcome.
