title: Idiopathic tension mediastinal emphysema cured by video-assisted thoracic surgery: a case report.
abstract: Mediastinal emphysema is a status of gas retention in mediastinum, usually caused by airway system injury or esophagus rupture. Healthy people without trauma and basic disease emerging unexplained mediastinal emphysema are called idiopathic mediastinal emphysema. While tension pneumomediastinum is an exceptional and potentially lethal condition, the increased intramediastinal pressure with a severe oppression of heart, vena cava and pulmonary vein leads to impaired central venous return through the cavae system, restricted right heart diastolic filling, and collapse of the cardiac chambers, resulting in reduced stroke volume, cardiac output and dysaemia. This young people-prone disease was initially reported by Hamman in 1939 and usually has a good prognosis so that no special treatments were needed. In this study, however, we presented a young boy with idiopathic tension mediastinal emphysema combined with dysaemia and respiratory failure. Fortunately, he was finally successful treated by VATS after heteropathy and incision on suprasternal fossae.
