Background of COPD. The first CXR is performed after bronchoscopic nitinol coil implantation in the right lung. Multiple nitinol coils are present in the right mid and upper lung. The second CXR is performed after treatment of the left lung and also shows multiple nitinol coils in the left mid and upper lung.
Patients with severe COPD can benefit from bronchoscopic lung volume reduction with nitinol coils. The coils are designed to reduce hyperinflation and improve elastic recoil in severe emphysema.
