title: Video-assisted thoracoscopic surgery in the prone position.
abstract: METHODS
  Review of 27 consecutive patients who underwent video-assisted thoracoscopic surgery (VATS) in the prone position for anterior release and discectomy.
  
  
  OBJECTIVE
  To convey the benefits and safety of this new technique for treating spinal deformities through VATS.
  
  
  BACKGROUND
  All reports using VATS for spinal deformities describe the patient in the lateral position. This is the first study to demonstrate the benefits and safety of the prone position.
  
  
  METHODS
  The patient is positioned prone, prepared, and draped allowing room for lateral portals on the convexity of the curve. Traditionally, a double-lumen endotracheal tube is used to deflate the ipsilateral lung. Prone positioning eliminates this need, because gravity aids in retraction of the lung.
  
  
  RESULTS
  All procedures were successfully performed using the VATS technique with the patient prone. After the anterior release and discectomy, posterior instrumentation (n = 27), costoplasty (n = 16), and fusion (n = 27) were performed. The time (n = 20) and blood loss (n = 16) for the anterior approach averaged 129 +/- 35 minutes and 221 +/- 231 mL, respectively. The mean number of disks resected was 3.3 +/- 0.7 (range, 2-5).
  
  
  CONCLUSIONS
  The prone position is both safe and effective for VATS when treating spinal deformity. The current results confirm that there is no need to insert a double-lumen tube, there is gravity-assisted correction of kyphosis when the patient is prone, and significant operative time is saved with the elimination of repositioning and redraping before the posterior procedure. Surgical times and blood loss compare very favorably with those reported for VATS in the lateral position.
