Trial Evaluating the Rate of Pneumothorax in Severe Emphysema Secondary to Endoscopic Volume Reduction With Two-stage ZEPHYR® Valves Versus Endoscopic Volume Reduction With One-stage ZEPHYR® Valves

Chronic obstructive pulmonary disease (COPD) affects 3.5 million people and is the third leading cause of death worldwide. Emphysema involves air retention in the lungs and is ultimately responsible for a major deterioration in the quality of life. Available drug treatments have moderate efficacy whereas surgical lung volume reduction can improve exercise capacity when offered to a very selected population but at the cost of significant morbidity and mortality. Endoscopic Lung Volume reduction with ZEPHYR® valves improves respiratory function at rest, exercise tolerance and quality of life in patients with little or no interlobar collateral ventilation. If this technique has therefore proven its effectiveness, it is not devoid of complications and is notably responsible for pneumothorax in 27% of cases. The management of this complication is clearly codified, ranging from patient monitoring to the removal of one or more valves. It is therefore a subject of major concern for multiple reasons: high incidence, lengthening of hospital stay, increase in the overall cost of care, potential loss of benefit for the patient in the event of permanent withdrawal. valves and above all a potentially fatal event. A new strategy for implanting ZEPHYR® valves in two stages has been developed in Limoges University Hospital. This innovative algorithm has been evaluated in several non-comparative single or multicenter studies. In those studies, pneumothorax' rate secondary to lung volume red…
