A secondary spontaneous pneumothorax occurs in the presence of existing lung disease. [3] [7] Smoking increases the risk of primary spontaneous pneumothorax, while the main underlying causes for secondary pneumothorax are COPD, asthma, and tuberculosis.
Catamenial pneumothorax is a spontaneous pneumothorax that recurs during menstruation, within 72 hours before or after the onset of a cycle. [1] It usually involves the right side of the chest and right lung, and is associated with thoracic endometriosis. [2] A third to a half of patients have pelvic endometriosis as well.
There are several causes for a tracheal deviation, and the condition often presents along with difficulty breathing, coughing and abnormal breath sounds. The most common cause of tracheal deviation is a pneumothorax, which is a collection of air inside the chest, between the chest cavity and the lung. A pneumothorax can be spontaneous, caused ...
Once the pneumothorax or pneumomediastinum that causes the subcutaneous emphysema is resolved, with or without medical intervention, the subcutaneous emphysema will usually clear. [18] However, spontaneous subcutaneous emphysema can, in rare cases, progress to a life-threatening condition, [ 5 ] and subcutaneous emphysema due to mechanical ...
Spontaneous pneumothorax is common. [24] In spontaneous unilateral pneumothorax, air escapes from a lung and occupies the pleural space between the chest wall and a lung. The lung becomes partially compressed or collapsed. This can cause pain, shortness of breath, cyanosis, and, if not treated, death.
Spontaneous, sometimes recurrent, [5] pneumothorax occurs far more often and at a younger age with BHD than in the unaffected population. Around 24% of people with the disease have at least one spontaneous pneumothorax, 30 times the occurrence in unaffected people.
A pneumothorax, also known as a collapsed lung, is a collection of air outside the lung in the pleural cavity. [14] Depending on etiology, a pneumothorax is classified as spontaneous, traumatic and iatrogenic. A spontaneous pneumothorax is further classified as primary and secondary, with the former occurring in individuals with no clinical ...
On radiological studies, pneumothorax is visualized using conventional chest x-rays and CT scans. In 90% of the cases, the pneumothorax is located on the right side. In some cases, small nodules can be seen in the pleura using CT scans. Confirmation can be done using video assisted thoracoscopic surgery (VATS). [8]
