title: [Success and complication rate of CT-guided marking of pulmonary nodules with coil wires for video-assisted thoracoscopic surgery (VATS)].
abstract: OBJECTIVE
  To assess the success and complication rate of the CT-guided marking of pulmonary nodules for video-assisted thoracoscopic surgery (VATS).
  
  
  METHODS
  Pulmonary nodules (mean diameter 9 +/- 5 mm, mean pleural distance 7 +/- 5 mm) were marked with a coil wire in 30 patients (20 males, mean age 57.6 +/- 15.5 years, 22 patients with a history of malignancy). The intended coil-nodule distance was < or = 10 mm.
  
  
  RESULTS
  81 % of nodules were not visible by thoracoscopy. The technical success rate of CT-guided marking was 86.7 %. The projected nodule-coil distance was achieved in 90 % of cases. The procedure had to be changed from thoracoscopy to thoracotomy in 4 patients due to coil wire marking problems: 2 x coil displacement, 1 x coil-nodule distance > 10 mm, unfavorable direction of wire. Histology was determined in all patients (70 % malignant, 30 % benign). Complications requiring therapy were not observed.
  
  
  CONCLUSIONS
  The CT-guided marking of pulmonary nodules is a precondition for VATS if the nodule does not involve the visceral pleura in the majority of cases. The success rate is high with a low complication rate.
