Lung volume reduction coil treatment for patients with severe emphysema: a European multicentre trial

This multicenter observational study evaluated midterm outcomes after use of the lung volume reduction endobronchial coil for severe emphysema in 60 pts.  The 30-day complication rate was moderate.  At 12 mos, the St. George's Respiratory Questionnaire decreased by 11.1 points, 6 min walk distance increased by 51.4 m, FEV1 increased by 0.11 L, and residual volume decreased by 0.71 L.
