Introduction:Bronchoscopic lung volume reduction (LVR) is a minimally invasive treatment for patients with advanced emphysema on maximal medical management. Bronchoscopic lung volume reduction surgery (BLVRS) refers to segmental atelectasis with endobronchial valves (EBV) to treat emphysematous hyperinflation via a flexible bronchoscope. Several inclusion and exclusion criteria exist for this procedure, without a clear age limit defined. We present the case of an 82 year old male who successfully underwent EBV placement for severe RUL emphysema.
Presentation:An 82 year old male with a PMH of COPD with emphysema presented for BLVRS evaluation for chronic SOB and exercise intolerance. At baseline, he required 2L of O2. His mMRC score was > 2. The patient had a 40 pack year smoking history, though quit 35 years ago. Recent PFTs showed FEV1 24%, RV 234%, TLC 113%. His 6 minute walk results were 354m on 2L O2. A high resolution CT scan confirmed upper lobe predominant emphysematous damage. He met criteria for BLVRS and elected to proceed with the procedure. The patient underwent bronchoscopy with placement of 3 EBVs in the apical, anterior, and posterior segments of the RUL. CXR the following morning revealed RUL atelectasis as expected without pneumothorax. The patient was successfully discharged 72 hours post procedure with close follow up.
Discussion:One-way EBVs are designed to facilitate atelectasis of the damaged, hyperinflated lung after confirmation of fissural integrity with balloon occlusion bronchoscopy. Consequently, we expect to see improvement in SOB and increased exercise tolerance. Proposed mechanisms include decreased air trapping and bronchoconstriction, improved elastic lung recoil, and improved diaphragm movement. Currently, patients considered for BLVRS have been evaluated under inclusion and exclusion criteria similar to those of the National Emphysema Treatment Trial (NETT). During that trial, the upper age limit used was 75. In our patient, all NETT criteria were met except for age. Our patient tolerated the procedure well, and though it is early to assess final outcomes, we propose that BVLRS should not be disregarded on age alone. More research must be dedicated to the use of BLVRS with the goal of improving dyspnea and exercise tolerance.
