Spontaneous pneumothorax is, as in humans, classified as primary or secondary, while traumatic pneumothorax is divided into open and closed (with or without chest wall damage). [63] The diagnosis may be apparent to the veterinary physician because the animal exhibits difficulty breathing in, or has shallow breathing.
LAM is sometimes revealed by chest CT in patients who present with an apparent primary spontaneous pneumothorax, but more often CT scanning is not ordered (in the United States) until recurrences occur. Progressive dyspnea on exertion without the exacerbations and remissions that are characteristic of asthma or COPD sometimes prompt a chest CT.
Common misdiagnoses include myocardial infarction, pancreatitis, lung abscess, pericarditis, and spontaneous pneumothorax. If esophageal perforation is suspected, even in the absence of physical findings, chest xray, water soluble contrast radiographic studies of the esophagus and a CT scan should be promptly obtained.
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.
Left-sided tension pneumothorax. Note the area without lung markings which is air in the pleural space. Also note the tracheal and mediastinal shift from the patient's left to right. Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax.
Pleurodesis is performed to prevent recurrence of spontaneous pneumothorax or pleural effusion, and can be done chemically or mechanically. It is generally avoided in patients with cystic fibrosis if possible, because lung transplantation becomes more difficult following this procedure. Previous pneumothorax with or without pleurodesis is not a ...
A spontaneous pneumoperitoneum is a rare case that is not caused by an abdominal organ rupture. This is also called an idiopathic spontaneous pneumoperitoneum when the cause is not known. [ 16 ] Causes of a spontaneous pneumoperitoneum, with no peritonitis include a barotrauma due to mechanical ventilation , and a tracheal rupture following an ...
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.
