What causes tracheal diverticulum?
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 tracheal pouch?
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 Tofs syndrome?
Oesophageal atresia is a rare birth defect that affects a baby’s oesophagus (the tube through which food passes from the mouth to the stomach). The upper part of the oesophagus doesn’t connect with the lower oesophagus and stomach. It usually ends in a pouch, which means food can’t reach the stomach.
Can diverticula pockets go away?
Once diverticula form, they do not disappear by themselves. Fortunately, most patients with diverticulosis do not have symptoms, and therefore do not need treatment.
Can a large tracheal diverticula cause dysphagia?
Large posterior tracheal wall diverticula may compress the esophagus and cause dysphagia. The differential diagnosis of a paratracheal air collection includes pharyngocele, esophageal diverticulum, laryngocele, apical hernia of the lung, and apical paraseptal blebs or bullae [5].
Can a tracheal diverticulum be congenital or acquired?
It may be congenital or acquired, the difference residing mainly in the histological features of the wall. Tracheal diverticulum is frequently an incidental finding in the postmortem examination, reported in 1% of patients in an autopsy series [1].
What kind of cyst is a tracheal diverticulum?
1 Introduction. Tracheal diverticulum is a paratracheal air cyst representing an out pouching of the tracheal wall. It may be congenital or acquired, the difference residing mainly in the histological features of the wall.
How is differential diagnosis of paratracheal air collection performed?
The differential diagnosis of a paratracheal air collection includes pharyngocele, esophageal diverticulum, laryngocele, apical hernia of the lung, and apical paraseptal blebs or bullae [5]. Both barium contrast study and CT scan of the neck and chest are useful noninvasive techniques for differential diagnosis.
