Pneumothorax is the abnormal presence of air in the space between the lungs and the chest cavity (known as the pleural space ), which can lead to a partial or complete collapse of the respective lung. Pathophysiology: Pneumothorax- A trauma occurs to the pleural space and air accumulates within the space. as the result of disease or injury. Summary. Pneumothorax. The causes of secondary spontaneous pneumothorax include: airway disorders such as emphysema, congenital anomalies, infectious lung disease, interstitial lung disease, connective tissue disorders, and malignant conditions . Recognizing that COPD and emphysema represent the most common causes of secondary spontaneous pneumothorax (SSP), investigators sought to determine the prevalence and incidence of SSP in individuals with emphysema and COPD in the United States, and to characterize risk factors for the condition. Secondary pneumothorax - pneumothorax caused by severe chest trauma (rib fracture, bullet wound, stab wound, etc.) A. Pleural white line B. Recurrent Spontaneous Pneumothorax will typically occur within 2 years of prior episode. The presentation of patients with pneumothorax varies depending on the following types of pneumothorax and ranges from completely asymptomatic to life-threatening respiratory distress: 1. Editor s: Antonella Melani, MD, Ian Mannarino, MD, MBA. Secondary spontaneous pneumothorax (SSP) occurs in people with a wide variety of parenchymal lung diseases. Spontaneous pneumothorax can be either small or large. Causes of pneumothorax. It is of two types, i.e., primary spontaneous pneumothorax and secondary spontaneous pneumothorax. 3. The most common associated etiology is chronic obstructive pulmonary disease (COPD), also known as chronic bronchitis or pulmonary emphysema. Overall recurrence rate: 20-60% (with similar rates on the contralateral side) Secondary Spontaneous Pneumothorax recurrence rate: 40-80%. The consequences of a pneumothorax in patients with pre-existing lung disease are significantly greater, Spontaneous pneumothorax is defined by the presence of air in the pleural cavity without history of trauma. It is called primary because it occurs in the absence of lung disease such as emphysema and spontaneous because the pneumothhorax was not caused by an injury such as a rib … A secondary spontaneous pneumothorax occurs when there is the presence of some lung disease or abnormalities. This leads to a loss of negative pressure between the two. There is no known way to prevent pneumothorax. However, you can lower your risk of developing pneumothorax by: Not smoking. Wearing a seatbelt when in a motor vehicle to help prevent accident-related chest trauma. Being aware of the symptoms associated with pneumothorax if you have another lung disease. Secondary spontaneous pneumothorax: Several lung diseases may cause a collapsed lung. The spontaneous pneumothorax can be primary or secondary and the treatment strategy is also decided on the basis of type of spontaneous pneumothorax. Patients also typically undergo a definitive procedure to prevent recurrence during the same hospitalization. There is a bimodal age distribution – neonates and late adolescence. The causes related to the production of pneumothorax are multiple and due to this fact, they have received different denominations such as iatrogenic, traumatic, barotrauma, and spontaneous (primary and secondary) 7). Tschopp JM, Rami-Porta R, Noppen M, Astoul P. Management of spontaneous pneumothorax: state of the art. Blebs and bullae may be related to an underlying disease process such as emphysema / chronic obstructive pulmonary disease, but they (blebs in particular) may also be found in young, healthy people with no other medical issues. Author: Anna Hernández Castillo, MD. Once a bleb ruptures and causes a pneumothorax, there is an estimated 13 to 60 percent chance that the condition will recur. The lung does not inflate normally, due to the presence of this unwanted air/gas. Prompt recognition and treatment of pneumothoraces is necessary to minimize morbidity and mortality. This occurs when air is trapped in the space around the lungs. 3 Pneumothorax occurs in 5% of patients with acquired immunodeficiency syndrome, is associated with subpleural necrosis by Pneumocystis infection, and carries a high mortality. Chronic necrotising pulmonary aspergillosis is a rare cause of pneumothorax. This diagnosis should be considered in patients experiencing pneumothorax with symptoms suggestive of tuberculosis and cavitary changes especially in the upper lobes. Most forms of pneumothorax require medical attention. The extent of this medical attention can vary as much as the disorder itself. The standard medical treatment usually involves inserting a small tube between the ribs or under the collarbone to release the gas that has built up. This will slowly decompress the lung. Air escapes from the lung into the pleural space through rupture of a small pleural bleb, or the pulmonary end of a pleural adhesion; Secondary Underlying lung disease, most commonly COPD and tuberculosis. Lung abscess, fungal disease, TB, Necrotic type of pneumonia; Cavitating neoplasm, metastatic osteogenic sarcoma Figure 1: Chest X-Ray showing pneumothorax secondary to blocked chest tube. About 16% to 20% of patients with cystic fibrosis >18 years of age will experience a pneumothorax at some time in their lives. Resident, Fellow, or Student. A pneumothorax is the presence of air between the two layers of pleura (thin, transparent, two-layered membrane that covers the lungs and also lines the inside of the chest wall), resulting in partial or complete collapse of the lung. Spontaneous pneumothorax develops in 2-6% of HIV infected patients[ii] and is associated with P. carinii pneumonia in 80% of those cases[iii]. Moreover, the outcome of surgical treatment for secondary spontaneous pneumothorax (recurrence of pneumothorax, hospital mortality, postoperative complications) depends on the underlying diseases , . There is no specific cause. Spontaneous pneumothorax represents a common clinical problem. Learn how UpToDate can help you. The incidence varies over time, as with the acquired immune deficiency syndrome (AIDS)-related Pneumocystis jirovecii pneumonia of the 1980s and 1990s. A primary spontaneous pneumothorax (PSP) tends to occur in a young adult without underlying lung problems, and usually causes limited symptoms. The main etiology of SSP is chronic obstructive pulmonary disease [4] . Pneumothorax can be classified as: Traumatic (result of an accident or … Secondary spontaneous pneumothorax (SSP) can be caused by a variety of lung diseases and disorders. chronic obstructive pulmonary disease and cystic fibrosis) Catamenial: in conjunction with menstruation (Neonatal) Traumatic Iatrogenic: secondary to transthoracic and transbronchial biopsy, Learn the pneumothorax or collapsed lung types, including the definition of a primary and secondary spontaneous pneumothorax vs tension pneumothorax vs traumatic pneumothorax. Primary spontaneous pneumothorax is more common in men than in women. The two subtypes of atraumatic pneumothorax are primary and secondary. Hemopneumothorax is a combination of two medical conditions: pneumothorax and hemothorax. fluid in pleural space. Spontaneous pneumothorax. These may … Chronic obstructive pulmonary disease is the most common cause. Secondary pneumothoraces: occur as a complication of an underlying pulmonary disease, including catamenial pneumothorax secondary to thoracic endometriosis. As discussed earlier, lung collapse results from an undesirable collection of air or gas between the chest and lung. Primary Spontaneous Pneumothorax (PSP) has an incidence of 7.4 to 18 cases among males and 1.2 to 6 cases among female per 100,000 populations each year. A primary spontaneous pneumothorax (PSP) occurs automatically without a known eliciting event, while a secondary spontaneous pneumothorax (SSP) occurs subsequent to an underlying pulmonary disease. A large pneumothorax can squash the lung and cause it to collapse. It has a peak incidence of 60–65 years of age. Primary spontaneous pneumothorax most commonly results from the bleb (small air-filled lesions under pleural surface) rupture allowing the air to leak into the pleural space. Most patients with secondary spontaneous pneumothorax (SSP) are treated with supplemental oxygen and removal of air from the pleural space, typically by chest tube thoracostomy. The occurrence of a spontaneous pneumothorax represents a troubling milestone in the course of patients with moderate-to-severe COPD. More cases of secondary spontaneous pneumothorax precipitated by pneumonia have been reported in children than in adults. Spontaneous pneumothorax can be further classified into primary with no clinical evidence of underlying lung disease or secondary due to pre-existing lung disease.” Spontaneous pneumothorax is a condition that is relatively rare in pediatrics. An overview of relevant and updated information on epidemiology, pathophysiology and cause(s) of spontaneous (primary and secondary) pneumothorax is described. Objective Silicosis is one of the common occupational lung diseases caused by crystalline silica respiration. What causes a spontaneous pneumothorax? Blocked chest tube Figure 2: Depressed right hemidiaphragm due to pneumothorax Table 1: Causes of iatrogenic pneumothorax according to frequency[11] Transthoracic needle aspiration or biopsy 24% Subclavian or jugular vein catheterization 22% Pneumothorax is a frequent and potentially fatal complication of mechanical ventilation in patients with acute respiratory distress syndrome (ARDS). Pneumothorax causes. We evaluated prevalence, clinical characteristics, and in-hospital mortality among Japanese patients with primary or Air in the pleural space occurring spontaneously or from trauma. Pathophysiology DR K . A primary spontaneous pneumothorax (PSP) occurs automatically without a known eliciting event, while a secondary spontaneous pneumothorax (SSP) occurs subsequent to an underlying pulmonary disease. This is an example of a secondary spontaneous pneumothorax due to emphysema. Secondary Spontaneous Pneumothorax. Causes of Secondary Spontaneous Pneumothorax Traumatic pneumothorax is a common complication of penetrating or blunt chest injuries. SSP carries more serious symptoms than PSP, and it is more likely to cause … It can also be caused by iatrogenic injuries. The most common cause is the placement of a subclavian central venous line (CVL). Most pneumothoraces occurring during anaesthesia and in the critically ill are classified into two categories: (i) pneumothorax secondary to barotrauma and (ii) traumatic pneumothorax as a result of thoracic injury from trauma, surgery, or other interventions. However, unlike primary spontaneous pneumothorax, patients with secondary pneumothorax often have another underlying respiratory disease present, such as tuberculosis (TB), COPD, pneumonia, among many. are primary or secondary pneumothroax more likely to require an intervention. [ 2] These individuals have underlying pulmonary pathology that … that tears the pleura. Pneumothorax DR RAMDHAN KUMAR KAMAT PG JLNMCH, BHAGALPUR 1. Pleural effusion. A small pneumothorax may cause few or no symptoms. Postprocedure pneumothorax is a rare complication of ultrasound-guided thoracentesis. Secondary sp… Pneumothorax is one of the most common and morbid complications of silicosis involving lung pleura. It is a traumatic pneumothorax secondary to an invasive procedure or surgery. 11 If the pressure becomes too great, the mediastinum shifts to the opposite hemithorax, and this causes compression of the contralateral lung and great vessels. Pneumothorax is the medical term for a collapsed lung. Optimal treatment practices and factors associated with in-hospital mortality in spontaneous pneumothorax (SP) are not fully understood. The overall person consulting rate for pneumothorax (primary and secondary combined) in the GPRD was 24.0/100 000 each year for men and 9.8/100 000 each year for women. Eur Respir J. Pneumothorax is the presence of air in the pleural space that prohibits complete lung expansion 12. A tension pneumothorax develops when air progressively accumulates under pressure within the pleural cavity. Secondary spontaneous pneumothorax occurs more in males too than female but at a smaller ratio of 3:1. The causes of secondary pneumothorax are listed in Table 58-2. A spontaneous pneumothorax is a collection of air or gas in the chest that causes the lung to collapse. together for the benefit of busy physicians. Primary No evidence of overt lung disease. pleural membranes. Iatrogenic pneumothorax is caused by medical interventions, including transthoracic needle aspiration, thoracentesis, central venous catheter placement, mechanical ventilation, and cardiopulmonary resuscitation. Causes. It can be further classified as primary (i.e., collapse of lung for no apparent reason) or secondary (i.e., collapse of the lung secondary to underlying pulmonary pathology), as detailed in Table 128-2 . The form of pneumonia known to cause pneumothorax is bacterial pneumonia. Our case series documents its absence with diagnostic thoracentesis when ultrasonography is employed in a controlled setting with expert supervision. Pneumothorax can be classified into tension and non-tension pneumothorax. Pneumothorax refers to the presence of air or gas in the pleural cavity between the visceral and parietal pleura, which results in violation of the pleural space, and although pediatric pneumothorax is uncommon, it can be life threatening. Secondary pneumothorax (SSP) is associated with underlying lung disease, in distinction to PSP, although tuberculosis is no longer the commonest underlying lung disease in the developed world. 2 , 3 Pneumothorax occurs in 5% of patients with acquired immunodeficiency syndrome, often from subpleural necrosis secondary to Pneumocystis infection, and carries a high mortality. Pneumothorax was significantly more common in TB patients < 30 years old (P < .001); the mean age of our pneumothorax group was 34 years, which is closer to the age distribution of patients with primary spontaneous pneumothorax (10–30 y) than with secondary pneumothorax (60–65 y), according to COPD population distribution. Overview. Airway diseases, including COPD, CF, and asthma, lead the list of causes of SSP, followed by infections such as PJP, tuberculosis, and necrotizing pneumonia. Like all spontaneous pneumothoraxes, secondary spontaneous pneumothorax occurs spontaneously. Catamenial pneumothorax is a rare form of secondary spontaneous pneumothorax that occurs within 48 hours of the onset of menstruation in premenopausal women and sometimes in postmenopausal … The pathophysiology of catamenial pneumothoraces is not known. It is commonly seen unilaterally in chronic silicosis and can often be lethal. Tall and thin adolescent males are typically at greatest risk, but females can also have this condition. Causes of secondary spontaneous pneumothorax are listed in Table 68-1. Spontaneous pneumothorax represents a common clinical problem. People who are affected by a PSP are often unaware of the potential danger and may wait several days before seeking medical attention. Secondary pneumothorax, defined as pneumothorax occurring in the setting of acute trauma (including iatrogenic) or underlying lung disease including but not limited to COPD, pulmonary fibrosis, TB, cystic fibrosis, lung cancer and asthma that requires regular preventative medication or has been symptomatic within the last two years Spontaneous pneumothorax: No clinical signs or symptoms in primary spontaneous pneumothorax until a bleb ruptures and causes pneumothorax; typically, the result is A secondary spontaneous pneumothorax occurs in patients with pre-existing pulmonary diseases.A tension pneumothorax is a medical emergency that requires immediate decompression.Patients with a pneumothorax. Unlike a PSP, a secondary pneumothorax is often larger and takes much longer to resolve. PNEUMOTHORAX PATHOPHYSIOLOGYPneumothorax is a topic you must know about in nursing school. The two subtypes of atraumatic pneumothorax are primary and secondary. Spontaneous pneumothorax: No clinical signs or symptoms in primary spontaneous pneumothorax until a bleb ruptures and causes pneumothorax; typically, the result is acute onset of chest pain and shortness of breath, particularly with secondary spontaneous pneumothoraces pneumothorax is further classified into primary and se-condary. Causes of secondary spontaneous pneumothorax are listed in Table 68-1. why are secondary pneumothorax geenrally more symptomatic. A secondary spontaneous pneumothorax occurs in a person who has a known lung disease or medical condition. The general incidence of secondary spontaneous pneumothorax (SSP) is almost similar to that of PSP. The risk of recurrence of spontaneous pneumothorax secondary to COPD is high and various studies quote rates 20-60%. Traumatic pneumothorax: results from either penetrating or blunt injury to the chest. Secondary spontaneous pneumothorax (SSP) occurs in association with a known underlying lung disease such as chronic obstructive pulmonary disease (COPD). Multiple bullae can develop in affected patients accompanied by pneumothorax. Non-Traumatic pneumothorax or spontaneous pneumothorax is the condition in which the pleural cavity is filled with the air without any injury. There is … COPD is a common cause of pneumothorax. Mohammed Areef Specialist in pulmonology B.G.H . Secondary spontaneous pneumothorax is a frequent occurrence in cystic fibrosis and is associated with more severe disease. The annual incidence of secondary spontaneous pneumothorax is 6.3 per 100,000 population in men and 2.0 per 100,000 in women. Because of necrosis of lung tissue and continued … […] Medical Professional. A traumatic pneumothorax can be the result of blunt or penetrating trauma. pleural space. Catamenial pneumothorax is a rare form of secondary spontaneous pneumothorax that occurs within 48 hours of the onset of menstruation in premenopausal women and sometimes in postmenopausal … These include chronic obstructive pulmonary disease (COPD), cystic fibrosis and emphysema.

An overview of relevant and updated information on epidemiology, pathophysiology and cause(s) of spontaneous (primary and secondary) pneumothorax is described. A pneumothorax can be small and get better with time. Primary spontaneous pneumothorax is an abnormal accumulation of air in the pleural space (the space between the lungs and the chest cavity) that can result in the partial or complete collapse of a lung. secondary - management more complex - prognosis less good. Primary versus Secondary Pneumothorax Patient or Caregiver. ... - causes bronchial hyperresponsiveness, constriction of airways, and reversible airflow obstruction Secondary spontaneous pneumothorax prevalence was significantly higher among Black individuals compared with white individuals, at 423 per 100,000 … An individual affected by pneumonia may develop secondary spontaneous pneumothorax as a complication. Start studying PHM 310 - Pathophysiology / Immunology (Respiratory Disorders-Pneumothorax) (Test 3). A primary spontaneous pneumothorax occurs in a person with no known lung problems. Causes of secondary spontaneous pneumothorax are listed in Table 68-1.Chronic obstructive pulmonary disease remains the most common cause. Symptoms include difficulty breathing and chest pain. Risk factors and causes include Marfan and Ehlers-Danlos. Hospital admissions for pneumothorax as a primary diagnosis occurred at an overall incidence of 16.7/100 000 per year and 5.8/100 000 per year for men and women, respectively. Secondary spontaneous pneumothorax is more serious than primary spontaneous pneumothorax because it occurs in patients whose underlying lung disease decreases their pulmonary reserve. Pneumothorax 3. Traumatic pneumothorax is caused by a blunt or penetrating chest injury. Causes and Risk factors: Spontaneous: Primary: Traumatic pneumothorax may result from eit-her blunt trauma or penetrating injury to the chest wall. Third Spontaneous Pneumothorax recurrence rate: >80%.

Hospital or Institution. A traumatic pneumothorax can be the result of blunt or penetrating trauma. Pneumothoraces can be spontaneous or traumatic/iatrogenic. A pneumothorax is a collapsed lung. A small spontaneous pneumothorax may resolve without treatment, while larger pneumothorax may need surgical intervention. Pneumothorax. Secondary spontaneous pneumothorax occurs in the presence of underlying lung disease, primarily chronic obstructive pulmonary disease; others may include tuberculosis, sarcoidosis, cystic fibrosis, malignancy, idiopathic pulmonary fibrosis, and pneumocystis jiroveci pneumonia. Today’s Top Picks for You on Pulmonology Advisor. This condition occurs in 7.4 to 18 per 100,000 men each year and 1.2 to … 1. PNEUMOTHORAX – Classification, Etiology, Risk Factors, Pathophysiology, Signs and Symptoms, Diagnostic Evaluations and Management . WHAT IS A PNEUMOTHORAX? Spontaneo-us pneumothorax is a significant health problem beca-use of the high recurrence rate (this is so called recur-rent pneumothorax). Injury-related pneumothorax: Injury to the chest can cause collapsed lung. Primary spontaneous pneumothorax (PSP) occurs in healthy indi- viduals without a coexisting lung disease, usually as a result of rupture of a pulmonary bleb. Group Practice.
