Endobronchial valve therapy for severe emphysema: an overview of valve-related complications and its management. Expert Rev Respir Med. 2020 Aug 26;: Authors: Koster TD, Klooster K, Ten Hacken NHT, van Dijk M, Slebos DJ Abstract INTRODUCTION: Bronchoscopic lung volume reduction treatment with one-way valves is an effective guideline treatment option for patients with severe emphysema. However, important challenges and adverse reactions may occur after treatment. AREAS COVERED: This review summarizes the complications after endobronchial and intrabronchial valve treatment that have been described by the currently published randomized controlled trials and other relevant papers regarding the complications and its management. In case there was no relevant literature regarding these subjects, recommendations are based on expert opinion. Complications include pneumothorax, post-obstruction pneumonia and hemoptysis. Also, the treatment may not be effective due to the presence of collateral ventilation or misplaced valves. Furthermore, an initial beneficial effect may vanish due to granulation tissue formation, valve dysfunction or valve migration. Careful follow up after treatment with valves is important. Evaluation with a CT-scan and/or bronchoscopy is needed if there is no improvement after treatment, loss of benefit or occurrence of important adverse events during follow up. EXPERT OPINION: Treating severe emphysema pat...
