RESUMEN

Tridimensional printing is becoming relevant in medicine, specially in surgical and interventional specialties. We review the technical aspects and clinical application of airway tridimensional printing. Using this technique, simulation models for bronchoscopy and models for diagnostic and therapeutic procedures such as stent design, tracheal reconstruction and airway models can be created.

RESUMEN

Chronic obstructive pulmonary disease (COPD) has no curative treatment, and in moderate to advanced stages, functional parameters and quality of life are affected. Lung volume reduction improves respiratory parameters and quality of life of these patients. Endoscopic lung volume reduction is a minimally invasive procedure that uses endobronchial valves or coils. Valves are unidirectional, blocking the air from entering the target lobe during inspiration, allowing the exit of air and secretions during expiration. Complete fissure and absence of collateral ventilation are needed for an adequate functioning of endobronchial valves. Endobronchial coils cause mechanical retraction of the lung parenchyma. We report two patients who underwent endoscopic lung volume reduction by endobronchial valves. One patient was on continuous positive pressure non-invasive ventilation due to his severe emphysema.
