Endobronchial valve
One-way endobronchial valves are placed in segmental bronchi of the most hyperinflated and least perfused lobe of the emphysematous lungs on computed tomography (CT). Before the procedure, we confirm that the target lobe has no collateral ventilation with other lobes using Chartis® System (Pulmonx, Inc. Redwood City, CA, USA).
