subcutaneous emphysema


Also found in: Dictionary, Thesaurus, Encyclopedia.

sub·cu·ta·ne·ous em·phy·se·ma

the presence of air or gas in the subcutaneous tissues.

subcutaneous emphysema

the presence of air or gas in the subcutaneous tissues. The air or gas may originate in the rupture of an airway or alveolus and migrate through the subpleural spaces to the mediastinum and neck. The face, neck, and chest may appear swollen. Skin tissues can be painful and may produce a crackling or popping sound as air moves under them. The patient may experience dyspnea and appear cyanotic if the air leak is severe. Treatment may require an incision to release the trapped air. Also called aerodermectasia.

emphysema

a pathological accumulation of air in tissues. The air may derive from a skin laceration and be drawn in by the movements of muscles. A discontinuity of the tracheal mucosa is a common cause, either by way of laceration or ulceration. Extension from a pulmonary lesion is also common. The syndrome resulting depends on the location of the air. See also pulmonary emphysema and subcutaneous emphysema (below).

acute bovine pulmonary emphysema
alveolar emphysema
see pulmonary emphysema (below).
bullous emphysema
emphysema in which bullae form in areas of lung tissue so that these areas do not contribute to respiration.
conjunctival emphysema
may occur after head trauma which permits escape of air from the paranasal sinuses.
fetal emphysema
see emphysematous/putrescent fetus.
generalized emphysema
widespread distribution of air, including subcutaneous tissues, seen with pneumomediastinum.
hypoplastic emphysema
pulmonary emphysema due to a developmental abnormality, resulting in a reduced number of alveoli, which are abnormally large.
interlobular emphysema
accumulation of air in the septa between lobules of the lungs.
interstitial emphysema
presence of air in the peribronchial and interstitial tissues of the lungs.
intestinal emphysema
a condition marked by accumulation of gas under the tunica serosa of the intestine.
lobar emphysema
emphysema involving less than all the lobes of the affected lung.
mediastinal emphysema
orbital emphysema
may occur after trauma to the head which permits escape of air from the paranasal sinuses; appears as swelling with crepitus under the conjunctiva or periocular skin.
panacinar emphysema, panlobular emphysema
generalized obstructive emphysema affecting all lung segments, with atrophy and dilatation of the alveoli and destruction of the vascular bed.
pulmonary emphysema
distention of the lung caused by overdistention of alveoli and rupture of alveolar walls (alveolar emphysema) and in some cases escape of air into the interstitial spaces (interstitial emphysema). It is a common pathological finding in many diseases of the lung in all species, but also occurs independently, especially in horses, as a principal lesion in chronic obstructive pulmonary disease. It is also a prominent lesion in bovine atypical interstitial pneumonia. It is always secondary to a primary lesion which effectively traps an excessive amount of air in the alveoli. It is characterized clinically by cough, dyspnea, forced expiratory effort and poor work tolerance. A double expiratory effort is a characteristic sign—hence broken wind.
subconjunctival emphysema
occurs with fractures involving the paranasal sinuses.
subcutaneous emphysema
air or gas in the subcutaneous tissues. The characteristic lesion is a soft, mobile swelling which crackles like stiff paper when palpated. There is no pain, nor heat and no ill effects unless the pharyngeal area is sufficiently involved to cause asphyxia.
surgical emphysema
subcutaneous emphysema following operation.
unilateral emphysema
emphysema affecting only one lung, frequently due to congenital defects in circulation.
vesicular emphysema
see panacinar emphysema (above).
