Traumatic chylothorax following blunt thoracic trauma: two conservatively treated cases.

Chylothorax is rare following blunt thoracic trauma; its diagnosis is usually delayed until the puncture or drainage of posttraumatic pleural effusion and its cause is not clear. Mostly, it is attributed to injury or overstretching of major thoracic duct by fractures or other injury of neighboring thoracic spine. We describe of two cases, one unilateral and one bilateral, of chylothorax, both after blunt thoracic trauma. In the first case, there were associated fractures of lower thoracic vertebrae, whereas in the other there was no obvious cause, except striking osteophytic degeneration alongside the thoracic spine. Both cases were successfully treated after 16 and 23 days, respectively, with drainage, starvation, reexpansion of the lung(-s), and total parenteral nutrition. We believe that with the "triad of RST" ("reexpansion, starvation diet, TPN"), conservative treatment will be successful in the majority of cases.
