What is the Bronchiectasis Medical Definition?
Bronchiectasis is an obstructive condition of the bronchial tree that causes irreversible destruction of the bronchial walls and results in the accumulation of copious amounts of bronchial secretions.
What are the Causes of Bronchiectasis?
The most common causes of Bronchiectasis include the following:
- Cigarette smoking/tobacco
- Cystic fibrosis
- Lung infections
- Autoimmune disorders
- Congenital disorders
- Foreign body obstruction
Most cases of Bronchiectasis stem from Cystic Fibrosis.
What are the Signs and Symptoms of Bronchiectasis?
The signs and symptoms of Bronchiectasis can vary in severity from person to person. Here are some of the most common examples:
- Chronic cough
- Large amounts of green/yellow purulent sputum
- Shortness of breath
- Chest pain
- Coughing up blood
- Cor pulmonale
Keep in mind that there are other signs and symptoms of Bronchiectasis. These are just the most common examples.
How is Bronchiectasis Diagnosed?
There are several things to look at when diagnosing a patient with Bronchiectasis. Here are the most common examples:
- Computed Tomography (CT) scan
- Immunoglobulin levels
- Sputum culture
- Pulmonary Function Tests (PFT)
- Complete Blood Count (CBC)
The physician may recommend a sweat chloride test if Cystic Fibrosis is suspected.
What is the Treatment for Bronchiectasis?
It’s ideal to strive to prevent Bronchiectasis but it can be managed by taking a comprehensive approach. Here are the general methods for treatment and management:
- Airway clearance therapy
- Anti-inflammatory medications
- Chest Physiotherapy (CPT)
- Pulmonary rehabilitation
- Oxygen therapy
Again, patients with Bronchiectasis are treated on a case by case basis and the methods can vary depending on the severity of their symptoms.
Bronchiectasis Practice Questions:
1. What is the definition of bronchiectasis?
Bronchiectasis is a chronic disease of the bronchi and bronchioles characterized by abnormal dilation, inflammation, and destruction of their walls. It is an irreversible lung disease seen in older adults that causes a chronic cough and recurrent lung infections. Lungs in this condition usually have an excess of puss and mucus. The bronchi and bronchioles will have permanent dilatation and thinning of airways. It retains inflammatory secretions and microbes that damage the airway and recurrent infection. Airway wall degradation is seen.
2. What are the causes of the bronchiectasis?
There is no known cause. It starts in childhood in many cases and, often, a secondary to other diseases like ciliary dyskinesia (Karatenger’s syndrome), AIDS, bronchial obstruction, aspiration, aspergillosis, cystic fibrosis, tuberculosis, smoke inhalation, rheumatoid, transplant rejection, and pertussis.
3. What is the pathophysiology of bronchiectasis?
The bacterial infection usually affects the segmental and sub-segmental bronchi.
4. What are the shapes of the destroyed bronchial walls?
Varicose, fusiform, saccular, cystic and cylindrical.
5. Why are distal areas obstructed?
It is due to secretions, inflammation
6. What are some signs, symptoms, and observations of bronchiectasis?
A continuous cough with a large amount of sputum, recurrent local pneumonia, occasional hemoptysis, and increasing dyspnea.
7. What is the breath sounds associated with a severe state of bronchiectasis?
Rales and rhonchi.
8. What is the old method to diagnose bronchiectasis?
9. What is the latest method used to diagnose bronchiectasis?
CT scan and HRCT.
10. What happens in the lungs of patients suffering from bronchiectasis?
Bronchial walls are destroyed, mucosa atrophied and cilia destroyed. The elastic area is filled with pus. Distal areas become obstructed.
11. What are some problems associated with bronchiectasis?
Clubbing, atelectasis, consolidation, increased

22. What is the etiology of bronchiectasis?
Most of the bronchiectasis disease is 50% idiopathic, 25% is a post-infection condition; another 15% is caused by systemic diseases. Many people with cystic fibrosis end up with bronchiectasis, but this is a small portion of the total population. This disease is not always clear in >60% of cases. It can be acquired or congenital which is approximately 50% of cases of cystic fibrosis and 20% from Kartagener’s Syndrome. It can also be due to past medical history of recurrent pulmonary infections. Patients with this condition present shortness of breath and possibly manifest pursed-lips breathing.

33. How do you treat chronic bronchiectasis with Pseudomonas?
34. How do you treat bronchiectasis?
There is no cure for this disease. Treatment and management of the symptoms of this disease are very important. Available management for bronchiectasis includes airway clearance, targeted antibiotics, airway hydration, bronchodilators, macrolides, and surgery to fix and contain the localized disease.
