Successful management of intractable chylothorax in Gorham-Stout disease by awake thoracoscopic surgery.

Gorham-Stout is an extremely rare disease, which is characterized by proliferation of vascular and lymphatic bone structures. A 15-year-old male patient was the diagnosis of Gorham-Stout disease of the cervical spine with chylothorax. Awake thoracoscopic ablation was performed using bronchoscopic tools and awake thoracoscopic debridement of the thoracoscopic cavities and chemical pleurodesis with OK-432 were repeated. The amount of drained liquid was controlled. There was no recurrence of pleural effusion.
