What does atelectasis mean on a CT scan?

What does atelectasis mean on a CT scan?

Atelectasis refers to either incomplete expansion of the lungs or the collapse of previously inflated lungs, which produces areas of relatively airless pulmonary parenchyma. Image depicting a right upper lobe collapsing posteriorly and inferiorly.

What are Atelectatic changes?

Atelectasis (at-uh-LEK-tuh-sis) is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing (respiratory) complications after surgery.

Is atelectasis reversible?

Atelectasis is reversible collapse of lung tissue with loss of volume; common causes include intrinsic or extrinsic airway compression, hypoventilation, and a malpositioned endotracheal tube.

What causes atelectasis?

Atelectasis, the collapse of part or all of a lung, is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the lung. Risk factors for atelectasis include anesthesia, prolonged bed rest with few changes in position, shallow breathing and underlying lung disease.

What are the 3 types of atelectasis?

The term atelectasis can also be used to describe the collapse of a previously inflated lung, either partially or fully, because of specific respiratory disorders. There are three major types of atelectasis: adhesive, compressive, and obstructive.

What are the symptoms of discoid atelectasis?

Symptoms of discoid atelectasis as with most other types of atelectasis are often confused for other illnesses. Symptoms such as breathing difficulties, chest pain and cough are general enough to make a diagnosis of the disease problematic.

How is atelectasis of the left lung determined?

Pulmonologists determine the types of atelectasis either depending on the specific features of its localization in airway structures – atelectasis of the right lung, atelectasis of the left lung, atelectasis of the lobe of the lung (lower, middle or upper), or taking into account its pathogenesis.

What causes a person to have adhesive atelectasis?

When that happens, it’s called adhesive atelectasis. It can be caused by serious lung problems such as respiratory distress syndrome or a bruised lung (pulmonary contusion). Cicatricial: This type of atelectasis is when the tissue that makes up your lungs has scars that keep them from being able to hold as much air as they should.

How are bronchial tubes used to treat discoid atelectasis?

Sometimes to relieve discoid atelectasis, bronchodilator medications are beneficial. It makes breathing easier by dilating the bronchial tubes and drains the mucus. Most cases of discoid atelectasis do not require to be treated as the alveoli re- inflates on its own over a period of time.
