Types Of Atelectasis

There are about three major types of atelectasis namely obstructive non-obstructive and adhesive. There are three major types of atelectasis.

The aim of each classification approach is to help identify possible underlying causes together with other accompanying radiological and clinical findings.

Types of atelectasis

. TYPES OF ATELECTASIS Atelectasis can be divided pathophysiologically into obstructive and nonobstructive atelectasis. Segmental lobar or whole lung. Acute atelectasis usually occurs after surgery involving the chest or abdomen.

Non-obstructive atelectasis can be caused by. TYPES OF ATELECTASIS Pulmonary atelectasis can be divided into six types on the basis of mechanism. In the early stages blood flow continues and gradually the oxygen and nitrogen get absorbed resulting in atelectasis.

As the name suggests this type of atelectasis is caused by blockage obstruction. Atelectasis is defined by either partial or complete collapse of lung parenchyma. Passive atelectasis occurs when the lung is allowed to retract eg due to presence of a pneumothorax.

Caused by dysfunction or deficiency of pulmonary surfactant. It may also occur after an injury to the chest. Atelectasis can be passive compressive resorptive cicatricial or discoid.

Among the three the most common is the obstructive atelectasis whereas the former is the least common. Atelectasis can be subcategorised based on underlying mechanism as follows. The different types of atelectasis have their own unique traits including different etiology and radiographic pattern.

Abnormal cardiac pacer leads positioning. Adhesive compressive and obstructive. There are two types of atelectasis acute and chronic.

Abnormal central venous catheter positioning. Atelectasis is a radiopathological sign which can be classified in many ways. Due to increased pressure on the lungs.

When airways are obstructed there is no further ventilation to the lungs and beyond. Resorptive adhesive compressive passive cicatrization and gravity-dependent. And generalized or diffuse.

Compressive atelectasis results from extrinsic compression of the lung by a space occupying process eg a bulla or lung mass. The following chapters review its imaging features and several underlying types. Platelike linear or discoid.

Whereas atelectasis can be divided into types on the basis of these different mechanisms in any given patient several mechanisms can occur simultaneously. Types of nonobstructive atelectasis include. Types of atelectasis.

Typical patterns of lung collapse and their associated radiographic signs are also described. This type of atelectasis involves most of the alveoli in one or more regions of the lung with the alveoli collapsing completely. Depending on the underlying cause atelectasis can involve either small or large portions of your lung.

A brief overview of pleural and lobar anatomy is. Obstructive atelectasis Obstructive ie resorptive atelectasis is a consequence of blockage of an airway 1. Atelectasis is different from a collapsed lung also called pneumothorax.

For descriptive purposes atelectasis can be divided into the following types. What Are The Three Types Of Atelectasis. What types of atelectasis may occur.
