Effect of airway stent on stenosed trachea

Abstract

Tracheal stenosis is a windpipe obstruction that can cause breathing problems. Besides, complications from past surgery or external injuries are several other common causes of tracheal stenosis. Besides, some other common causes of tracheal stenosis are complications from previous surgery or external injuries. Computational fluid dynamics (CFD) technique is allowed to understanding to flow characteristic inside stenosed trachea. This study uses patient computed tomography (CT) images to investigate the relationship of pressure distribution and air flow rate in the tracheal airway. In order based on CT-scans of a patient for all breathing condition. We assessed flow patterns and pressure drops over tracheal stenosis artificially inserted into a actual three-dimensional upper airway model. The actual airway model is extremely irregular and the presence of stenosis adds to its geometrical complexity, resulting in very complex flow patterns with flow separations. In this analysis, the findings show air flow velocity and pressure with trachea stenosis and stenting.
