Particularly patients who develop atelectasis benefit from valve therapy.Methods: Retrospective analysis of the incidence of a complete atelectasis following valve treatment in patients treated from 01/2008 to 12/2013 in the Thoraxklinik Heidelberg.Results: From 01/2008 to 12/2013, 373 patients were treated by valves (217 x EBV (Pulmonx Inc., USA), 101 x IBV (Olympus Inc., Japan), 55 x EBV/IBV). 234 patients received valves on the left, 136 on the right and 3 patients were treated bilaterally. 115 patients (30.8%) experienced a complete atelectasis. The incidence of atelectasis at a rate of 35.9% (84/234) following a left-sided therapy was higher compared to 22.8% (31/136) following a right-sided treatment. 40.1% of the atelectasis (87/217) occurred following EBV placement, 20.8% (21/101) following IBV placement. 12.7% of patients (7/55) who developed atelectasis received EBV as well as IBV. Regarding at the incidence of atelectasis following valve therapy based on the years, a significant increase can be observed.Discussion: The overall incidence of an atelectasis following valve therapy in the last 5 years is 30.8%. However, a significant increase can be observed over the years. This can be explained that since the end of 2010 the fissure integrity is increasingly respected. ER -
