title: Pericardial cysts: an analysis of 12 cases.
abstract: BACKGROUND
  Pericardial cysts are usually asymtomatic, benign, congenital mediastinal lesions but may also be acquired after cardiothoracic surgery. The purpose of the study was to evaluate surgical approach and results of our experience with pericardial cysts.
  
  
  METHODS
  A total of 12 patients who had undergone surgical treatment for pericardial cyst between February 1999 and August 2010 were retrospectively evaluated. All patients were analyzed according to the symptoms, method for the diagnosis, cyst location, management, and outcomes.
  
  
  RESULTS
  The mean age was 50.4±17 years (range, 23-68 years) with a female-to-male ratio of 8:4. Pericardial cyst were located in the right hemithorax in 8 (67%) patients and left hemithorax in 4 (33%) patients. The cysts were resected by thoracotomy in 4 (33%) patients and by video-assisted thoracic surgery in 8 (67%) patients. There was an excellent long-term follow-up with no morbidity or mortality.
  
  
  CONCLUSIONS
  Videothoracoscopic surgical removal of pericardial cysts is an excellent surgical intervention without serious morbidity and mortality.
