Tracheobronchomalacia may also occur in people who have normal cartilaginous structure of the trachea, but significant atrophy of the posterior wall, causing significant invagination of the trachea on expiration. In these cases it is more commonly known as excessive dynamic airway collapse (EDAC).
Dynamic compression of the airways results when intrapleural pressure equals or exceeds alveolar pressure, which causes dynamic collapsing of the lung airways. It is termed dynamic given the transpulmonary pressure (alveolar pressure − intrapleural pressure) varies based on factors including lung volume, compliance, resistance, existing pathologies, etc. [1]
Several videos and photographs of the hole left by the plane show a living woman inside the hole, generally identified as Edna Cintrón, waving at people in the streets below. [ 6 ] [ 7 ] The victim appears outside among the mass of iron and leaning on one of the ruins of the structure while shaking her hand, and right arm.
Cross-sectional radiological images are important in detecting mediastinal structures involved in TM prior to surgery. Tracheography/ Bronchography is no longer a preferred diagnostic method. Bronchography provides an accurate measurement of the airway lumen with a dynamic and morphological evaluation of the tracheobronchial tree .
Four-dimensional computed tomography (4DCT) is a type of CT scanning which records multiple images over time. It allows playback of the scan as a video, so that physiological processes can be observed and internal movement can be tracked.
NEW LONDON, Conn. (AP) — An historic Connecticut church's soaring steeple and roof collapsed on Thursday, leaving a gaping hole in the top of the building and the front reduced to a heap of rubble.
Furthermore, when a patient lays supine for a CT scan, the posterior lungs are in a dependent position, causing partial collapse of the posterior alveoli. This leads to an increase in density of the tissue, resulting increased attenuation and a possible ground-glass appearance on CT.
