The cause of primary spontaneous pneumothorax is unknown, but established risk factors include being of the male sex, smoking, and a family history of pneumothorax. [18] Smoking either cannabis or tobacco increases the risk. [3] The various suspected underlying mechanisms are discussed below. [12] [13]
[citation needed] An abrupt worsening in COPD symptoms may cause rupture of the airways in the lungs, which in turn may cause a spontaneous pneumothorax. [4] In infection, there is often weakness, fever and chills. If due to a bacterial infection, the sputum may be slightly streaked with blood and coloured yellow or green. [5]
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 ...
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 ...
Ectopic endometrial tissue reaches the pleural space of the lung or the right hemi-diaphragmatic region and erodes the visceral pleura, causing the formation of a spontaneous pneumothorax. The condition is often cyclical, due to its associations with the beginning of the menstrual cycle. [8]
Those with an abnormal accumulation of air within the pleural space (a pneumothorax) can bleed into the cavity, which occurs in about 5% of cases of spontaneous pneumothorax, [8] especially when lung bullae rupture. [11] The resulting combination of air and blood within the pleural space is known as a hemopneumothorax. [8]
Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax. Other causes include abdominal compartment syndrome, Hiatal hernia, severe aortic valve stenosis, and disorders of the aorta. Constrictive pericarditis is a rare cause.
