What causes blebs and bullae

Exactly which patients are most likely to benefit and the magnitude of the benefit remain controversial.

Pulmonary Blebs and Bullae

On some occasions, a collapsed lung can be a life-threatening event. However, even patients who are aggressively treated may occasionally experience progressive dyspnea, airflow obstruction, exercise limitation, and poor quality of life.

In a patient who requires bilateral intervention, median sternotomy is often used to allow access to both lungs via one incision.

Emphysema in the lung surrounding the bulla appears to increase the risk of prolonged air leak.

Primary spontaneous pneumothorax

As the remaining lung stretches to fill the space previously occupied by the bulla, elastic recoil is increased, helping to pull open small airways and improve expiratory airflow. The procedure is performed with general anesthesia using a special endotracheal tube that allows intentional collapse of the lung which is operated on.

apical bulla in right lung

In the vast majority of cases, blebs remain asymptomatic. Air in the pleural space creates pressure on the lung and can lead to its collapse.

Many people who have had one pneumothorax can have another, usually within one to two years of the first. Epub 2005 Jan 18.

The laboratory workup of a patient with bullous emphysema is not standardized, but it may include the following considerations: Familial spontaneous pneumothorax and lung cysts due to a Folliculin exon 10 mutation.

Collapsed and normal lung In a collapsed lung, air from the lung leaks into the chest cavity. Cavities are usually thick-walled collections formed by focal necrosis within a consolidation, mass, or nodule.

Bullous Lung Disease (includes HIV-related emphysema)

Pneumatoceles are temporary tents in the lung parenchyma that usually arise from blunt trauma or over-distension of the lung. With pneumothorax the air-filled space lies outside visceral pleura, rather than within lung parenchyma. Patients with blebs will typically have emphysema.

However, they usually demonstrate obstructive lung disease. Pulmonary hypertension: Advertising revenue supports our not-for-profit mission. In most cases, a person inherits the FLCN gene mutation from an affected parent. Lose weight. Case 2: Exposures and environmental factors: Shields TW. Common abnormalities include airflow obstruction, hyperinflation i.
