Silicone stent acting as a support in a tracheal stenosis at the level of the first rings. The vocal cords are somewhat thickened and with obvious congestion in the mucosa in its posterior third, close to the arytenoids.
Complex tracheal stenosis after endo-surgical treatment. Image taken one month after a stent, that remained for 2 years, was removed. There is sufficient tracheal light and some changes in its relief due to the presence of granulomas on the left wall. The edema erases the longitudinal folds and the silhouette of the cartilages.
Radial cuts at hours 3 and 9, performed with electrocautery. Procedure prior to dilation of a simple tracheal stenosis. The radial cut is also a safety measure reducing the risks of rupture of the posterior membrane during the dilation maneuvers.
The light from the left source bronchus is greatly reduced due to a stricture established after a complete bronchial rupture due to chest trauma. The reduction of the bronchial diameter is concentric and progressive or “infundibuliform”. The edema thickens the mucosa and the cartilaginous reliefs and also the linear folds of the posterior wall of … Read more
Tracheal stenosis that forms a double diaphragm of fibrous tissue. At the distance, a second stenosis can be seen with little punctate light, the only way available for ventilation.
Strangely, a “T” tube has lost its alignment with the trachea. Inspection from the glottis identifies its end that rests on inflamed tissue in the posterior wall, full of secretions. Alejandro Posadas Hospital
Consolidated stenosis, central and short, below the prominence of the first tracheal ring. Asymptomatic, because its diameter exceeds 8mm. (Isidoro, R. Prolonged prolonged implant prosthesis: 10 years, RAMR 2016; 3: 250-257)
Central benign tracheal stenosis, with several fibrous arches. Its thin edges together with its pallor indicate an absent inflammatory state. Condition very suitable for open surgical treatment.
Subglottis: at short distance from the vocal cords a simple stenosis, in diaphragm, considerably reduces the light. Ventilation is possible thanks to a central and circular hole, with a small marginal nodule. The same volume of inhaled air must increase its speed to enter through a narrow light, becoming turbulent, which causes visible hyperemia in … Read more
Laryngeal stenosis that has evolved towards the total closure of light at the level of the subglottis. The patient suffers a post-intubation rash with damage to the laryngeal cartilages. It develops a subglottic stenosis that, when it becomes symptomatic or critical, receives the relief of the tracheostomy at the hands of the surgeon. However, this … Read more
