What is the most common location of a tracheal diverticulum?
Tracheal diverticula are usually located at the right posterolateral region of the trachea (97.1%) and rarely located at the left side (2.9%) (4).
What causes tracheal diverticulum?
Acquired tracheal diverticulum has a wide opening and can be found at any level in the thoracic cavity. The proposed cause is the herniation of the weakened tracheal wall due to increased luminal pressure in the trachea, such as in the environment observed in chronic obstructive pulmonary disease [ 2].
What is a small tracheal diverticulum?
A tracheal diverticulum is a pouch in the trachea (windpipe). It is often a small piece of esophageal tissue that remains on the trachea after a child undergoes surgical repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). Rarely, a child may be born with a congenital tracheal diverticulum.
What is tracheal diverticulum in adults?
Tracheal diverticulum is defined as an air cyst located on the lateral wall, congenital or acquired. Most of them are asymptomatic, incidentally found on CT. The common symptoms are chronic cough, stridor, or recurrent respiratory infections.
How is tracheal diverticulum treated?
Treatment options of tracheal diverticulum include surgical resection and conservative management. Treatment options change depending on the patient’s symptoms, age and physical state. Surgery is recommended for symptomatic patients, conservative medical treatment for elderly and debilitated patients.
What is respiratory diverticulum?
the endodermal diverticulum from the floor of the caudal end of the primordial pharynx; it gives rise to the epithelium and glands of the bronchial tree. After this diverticulum separates from the foregut, it is referred to as a tube.
How is esophageal diverticulum treated?
How is esophageal diverticulum treated? Cases of esophageal diverticulum that cause minor symptoms can be treated through lifestyle changes, such as eating a bland diet, chewing food thoroughly, and drinking plenty of water after meals.
What is Zenker diverticulum?
A Zenker’s diverticulum is an outpouching that occurs at the junction of the lower part of the throat and the upper portion of the esophagus. The pouch forms because the muscle that divides the throat from the esophagus, the cricopharyngeal (CP) muscle, fails to relax during swallowing.
Is the respiratory diverticulum the lung bud?
The lung bud sometimes referred to as the respiratory bud forms from the respiratory diverticulum, an embryological endodermal structure that develops into the respiratory tract organs such as the larynx, trachea, bronchi and lungs. It arises from part of the laryngotracheal tube.
How many secondary bronchi are on the right lung?
3 secondary bronchi
The right main bronchus gives rise to 3 secondary bronchi: right upper lobe bronchus. right middle lobe bronchus.
Which imaging studies are used to diagnose tracheal diverticulum?
Thin-section multidetector computed tomography (MDCT) is useful for diagnosis of tracheal diverticulum. The relationship between DV and tracheal lumen can be demonstrated by axial, coronal, and sagittal reformat multiplanar images. Bronchoscopy can also be used in diagnosis for tracheal DV.
Can tracheal diverticula be asymptomatic?
Tracheal diverticula are typically asymptomatic but can occasionally present with chronic cough, stridor, dyspnea, or recurrent infection 5 . Tracheal diverticula can be 5:
What are tracheal diverticula (tracheoceles)?
Tracheal diverticula, also known as tracheoceles, are usually an incidental finding. Occasionally it may mimic pneumomediastinum, so-called pseudopneumomediastinum.
What is the prevalence of tracheal diverticulum?
The reported prevalence of PTACs ranges from 0.75–8.1% (1-3). Tracheal diverticulum (DV) consists of small air collections at the paratracheal area lined by ciliated columnar epithelium. Tracheal DV is commonly asymptomatic and incidentally detected by imaging methods. The incidence of tracheal DV is 2.4% (4).
