Abstract
Severe emphysema patients who have been treated with endobronchial coils have been shown to initially benefit, but slowly decline in the years thereafter. Re-treating a patient with endobronchial coils could potentially lead to new improvements and may again reduce the rate of further decline. To our knowledge, until now, no results are published about patients who are re-treated. The primary aim of this study is to investigate the safety and feasibility of re-treating severe emphysema patients with endobronchial coils, using the PneumRx coil system. Furthermore, as secondary aim, we will evaluate the efficacy of re-treating these patients. Patients who at least 2 years ago were treated with endobronchial coils and responded clinically meaningful to this treatment were included in the study and re-treated. Safety was evaluated by the number of reported adverse events. Efficacy was evaluated 6 months after re-treatment, and measured by the change in quality of life, exercise capacity and pulmonary function testing. Eight patients were re-treated at a median of 1382 days (range 849-1545) after initial coil treatment with a median additional of 12 (10-15) coils per patient. During treatment, and until 6 months of follow-up, no une...Continue Reading
