What means Subsegmental atelectasis?

What means Subsegmental atelectasis?

Terminology. The term subsegmental atelectasis includes any loss of lung volume so small that it does not cause indirect signs of volume loss (as might be seen with larger atelectases).

What is plate atelectasis in lung?

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.

What is obstructive atelectasis?

Obstructive atelectasis is the most common type and results from reabsorption of gas from the alveoli when communication between the alveoli and the trachea is obstructed. The obstruction can occur at the level of the larger or smaller bronchus.

What causes resorption atelectasis?

Resorption atelectasis is caused by resorption of alveolar air distal to obstructing lesions of the airways; adhesive atelectasis stems from surfactant deficiency; passive atelectasis is caused by simple pneumothorax, diaphragmatic dysfunction, or hypoventilation; compressive atelectasis is due to tension pneumothorax.

What does lingular subsegmental atelectasis mean in medical terms?

Partial Collapse: The lingula is the lower anterior (front) portion of the left upper lobe of the lung that corresponds to the right middle lobe. Atelectasis is collapse of a portion of the lung. So, subsegmental atelectasis means that portions of lung segments of the lingula are incompletely aerated.

What are the subcategories of lung atelectasis?

Atelectasis can also be subcategorised by morphology : linear (a.k.a. plate, band, discoid) atelectasis : a minimal degree of collapse as seen in patients who are not taking deep breaths (“splinting”), such as postoperative patients or patients with rib fracture or pleuritic chest pain; this is very common

What does round atelectasis mean in medical terms?

lobar atelectasis: collapse of one or more lobes of a lung. round atelectasis : classically associated with asbestos exposure.

Can you get atelectasis from breathing in a foreign object?

It’s also a possible complication of other respiratory problems, including cystic fibrosis, lung tumors, chest injuries, fluid in the lung and respiratory weakness. You may develop atelectasis if you breathe in a foreign object.
