Bronchiectasis is destruction and widening of the large airways.
Acquired bronchiectasis; Congenital bronchiectasis
Causes, incidence, and risk factorsBronchiectasis is often caused by recurrent inflammation or infection of the airways. It most often begins in childhood as a complication from infection or inhaling a foreign object.
Cystic fibrosiscauses about half of all bronchiectasis in the United States. Recurrent, severe lung infections (pneumonia, tuberculosis, fungal infections), abnormal lung defenses, and obstruction of the airways by a foreign body or tumor are some of the risk factors.
The condition can also be caused by routinely breathing in food particles while eating.
SymptomsSymptoms often develop gradually, and may occur months or years after the event that causes the bronchiectasis.
They may include:
When listening to the chest with a stethoscope, the doctor may hear small clicking, bubbling, wheezing, rattling, or other sounds, usually in the lower lobes of the lungs.
Tests may include:
Treatment is aimed at controlling infections and bronchial secretions, relieving airway obstruction, and preventing complications.
Regular, daily drainage to remove bronchial secretions is a routine part of treatment. A respiratory therapist can show the patient coughing exercises that will help.
Antibiotics, bronchodilators, and expectorants are often prescribed for infections.
Surgery to resect the lung may be needed if medicine does not work or if the patient has massive bleeding.
Expectations (prognosis)With treatment, most people can lead normal lives without major disability.
ComplicationsCall your health care provider if:
The risk may be reduced if lung infections are promptly treated.
Childhood vaccinations and a yearly flu vaccine help reduce the chance of some infections. Avoiding upper respiratory infections, smoking, and pollution may also reduce your risk of infection.

Causes, incidence, and risk factorsBronchiectasis is often caused by recurrent inflammation or infection of the airways. It most often begins in childhood as a complication from infection or inhaling a foreign object.
Cystic fibrosiscauses about a third of all bronchiectasis cases in the United States. Certain genetic conditions can also cause bronchiectasis, including primary ciliary dyskinesia and immunodeficiency syndromes.
The condition can also be caused by routinely breathing in food particles while eating.

bronchiectasis
Chest x ray may reveal evidence of bronchiectasis, and CT scans are particularly good at revealing the thick, dilated bronchial walls of bronchiectasis. Sputum will need to be collected and cultured (grown in a laboratory dish).
Bronchiectasis is the medical term meaning chronic enlargement of the bronchioles.
James R. Lisa has written: 'Bronchiectasis; pathogenesis, pathology and treatment' -- subject(s): Bronchiectasis
In bronchiectasis, the diameter of the bronchi is unusually large. Examination of the walls of the bronchial tubes reveals destruction of the normal structural elements, with replacement by scar tissue. Pus collects within the bronchi and.

Bronchiectasis is the medical term for dilation of the bronchi. It is a chronic necrotizing infection of bronchi & bronchioles causing abnormal permanent dilation of these airways.Rationale: Dilation (-ectasis) of the bronchi (bronchi/o = bronchus).treakia i thinkbronchiectasis
