Pneumothorax is one of diseases that listed in the lining of the lungs called Pleura. The pleura is a cavity located between the membrane that lines the lungs and chest cavity . So the rays penetrating chest visible presence of air in the cavity . This is what is pneumothorax . While under normal circumstances the pleural cavity contains no air to inflate the lungs freely against the thoracic cavity . Diagnosis of pneumothorax depends on the line formed at the edge of the pleura that separates the lungs and chest wall , mediastinum or diaphragm by air , and also the lack of a shadow outside the lines .
Entry of air into the pleural cavity is distinguished in two ways :
Spontaneous pneumothorax occurs in patients who have not found any lung diseases before. This type of pneumothorax caused by rupture of a small air-filled sacs in the lungs called a bleb or bulla . The disease often strikes in a tall – skinny men , aged 20-24 years . Factors that tend to cause this disease is cigarette smoking and family history of the same disease . This condition can occur repeatedly and often become chronic conditions .
While in secondary spontaneous pneumothorax is a complication of lung disease , such as chronic obstructive pulmonary disease , asthma , cystic fibrosis , tuberculosis , and whooping cough .
Traumatic Pneumothorax occurred due to a traumatic injury to the chest . Are penetrating trauma such as stab and bullet wounds , or blunt as impact on motor vehicle crashes . In addition , it could be due to complications of medical treatment , for example Torakosentesis . Outside air into the pleural cavity through a stab wound or pneumothorax intentional (artificial ) with therapy , in terms of expenditure or diminution cavity present specific process is not done anymore . Accidentally on purpose pneumothorax is a diagnostic to distinguish the masses , whether it comes from the pleura or lung tissue . While other causes of pneumothorax and lung biopsy is the act of discharge pleural cavity .
Entry of air through the mediastinum usually caused by trauma to the trachea or esophagus due to actions by inspection tools ( endoscopy ) or sharp foreign objects ingested . Malignancy in the mediastinum can also cause air in the pleural cavity through the fistula between the proximal airway pleural cavity . The air can also be derived from subdiafragma with a torn stomach caused by trauma or asbestos subdiafragma with gas -forming bacteria .
