Chest tube insertion is the standard treatment for large or symptomatic pneumothorax, but whether or not it is necessary or beneficial in the subset of patients with ex vacuo pneumothorax is not known. Major causes of pneumothorax in patients undergoing thoracentesis are direct puncture during needle or catheter insertion, the introduction of air through the needle or catheter into the pleural cavity, and the inability of the ipsilateral lung to fully expand after drainage of a large volume of fluid, known as pneumothorax ex vacuo. Thoracentesis is a percutaneous procedure in which a needle or catheter is passed into the pleural space for evacuation of pleural fluid. ... Other differentials include pneumothorax ex-vacuo (particularly right upper lobe collapse), cryptogenic organizing pneumonia, chronic pulmonary consolidations, and bronchiolitis obliterans organizing pneumonia. The second is characterized by violation of the parietal pleura as seen during subclavian line placement, for example. If thoracentesis has been performed or attempted, patients can develop a hydropneumothorax or pneumothorax ex vacuo due to the lungâs inability to expand (Figures 10, 11). In this condition, acute bronchial obstruction from mucous plugs, aspirated foreign bodies, or malpositioned endotracheal tubes causes acute lobar collapse and a marked increase in negative intrapleural pressure around the collapsed lobe. "Management of patients with "ex vacuo" pneumothorax after thoracentesis ". Careful recognition of this type of pneumothorax may save patients and physicians When draininga large pleural effusion, the main concern is that excessive fluid removalcould lead to re-expansion pulmonary edema. Pneumothorax ex vacuo (169 words) exact match in snippet view article find links to article (2005). also found that the presence of an ex vacuo pneumothorax in the context of malignant disease is associated with a poor prognosis.13 We conclude that, if an ex vacuo pneumothorax occurs after drainage of a pleural effusion due to non-expansile or trapped lung, the pneumothorax should not routinely be drained. Pneumothorax following thoracentesis is associated with increased morbidity, mortality and length of hospital stay (4,5). Effusions related to NEL also tend to be rapidly recurrent, further supporting the use of IPCs in those with symptoms. Pneumothorax ex vacuo remains remarkably stable following removal of the negative suction and is rapidly replaced by fluid as was the case in our patient. use of manometry could anticipate the development of chest discomfort during therapeutic thoracentesis. However, it is uncommonly reported with the use of noninvasive positive pressure ventilation (NPPV) and CPAP (continuous positive airway pressure) therapy. A small-bore chest tube was inserted and placed on suction without any additional re-expansion of the lung or any change in his respiratory status (Figure 1). Tension pneumothorax: occurs when the intrapleural pressure exceeds atmospheric pressure throughout expiration and often during inspiration. Overall, 6.0% of thoracenteses were complicated by the development of pneumothorax, and 34.1% of pneumothoraces (1.7% of all thoracenteses) required chest tube insertion. F1000 Med Rep. 2010;2:77. A small-bore chest tube was inserted and placed on suction without any additional re-expansion of the lung or any change in his respiratory status (Figure (Figure1). ex vacuo. No serious complications occurred in either group. Subsequent X-rays post catheter placement conï¬rmed persistence of pneumothorax ex vacuo with no pleural apposition in all. Unlike spontaneous or tension pneumothoraces, pneumothorax ex vacuo does not require chest tube placement. A small-bore chest tube was inserted and placed on suction without any additional re-expansion of the lung or any change in his respiratory status (Figure 1). Management depends on the underlying cause and should aim to alleviate the endobronchial obstruction. One relatively common complication is chest discomfort, which is most of the time felt to be secondary to negative pleural pressures generated during the procedure. Conceptually, pneumothorax is categorized as stable or unstable. Ponrartana S, Laberge JM, Kerlan RK, Wilson MW, Gordon RL (2005) Management of patients with âex vacuoâ pneumothorax after thoracentesis⦠Accordingly, they are Pneumothorax ex vacuo is a rare type of pneumothorax which forms adjacent to an atelectatic lobe. The most common complication of thoracentesis is pneumothorax. Two large volume Diagnoses were malignant pleural mesothelioma in 7 and pleural adenocarcinoma in 3. Radiographically, this may be identified as a pneumothorax ex vacuo 10 (ie, caused by inability of the lung to expand to fill the thoracic cavity after pleural fluid has been drained) and is not a procedure complication. Chest 110:1102â1105. Ex vacuo pneumothorax is a form of pneumo-thorax that occurs after pleural intervention, such as thoracentesis when the lung is unable to expand to fully fill the pleural space. Pneumothorax ex vacuo is a little-known complication of lobar collapse. Management depends on the underlying cause and should aim to alleviate the endobronchial obstruction. In our experience, the rate of pneumothorax is near zero when pneumothorax ex vacuo is excluded. It is also seen following removal of pleural effusion by thoracentesis when the collapsed lung struggles to re-expand. demonstrated improvement in patient symptoms with fluid removal despite occurrence of an ex vacuo pneumothorax. A small-bore chest tube was inserted and placed on suction without any additional re-expansion of the lung or any change in his respiratory status. 8 In addition a study by Boland et al. Woodring JH, Baker MD, Stark P (1996) Pneumothorax ex vacuo. This may result in a pressure-dependent parenchymal pleural fistula, with the development of a pneumothorax âex vacuoâ. In 2 thoracocentesis patients, post procedural X-rays showed clear large hydro-pneumothoraces and those patients had ICDs inserted. INTRODUCTION. Indications â The indication for large volume thoracentesis is dyspnea due to a moderate to large pleural effusion confirmed by physical examination and chest radiography. Thoracentesis is a very common procedure, rarely associated with severe complications. It is seen preferentially with atelectasis of the right upper lobe and is the result of rapid atelectasis producing an abrupt decrease in the intrapleural pressure with subsequent release of nitrogen from pleural capillaries.. A chest computed tomographic scan revealed a septated area of ex vacuo pneumothorax with collapsed lung and a left pleural effusion . 01). REFERENCES. Post-thoracentesis, he had a large hydropneumothorax suspicious for a pneumothorax ex-vacuo. defined as pneumothorax (including pneumothorax ex vacuo requiring hospitalisation or observation), haemothorax, re-expansion pulmonary oedema and continued leak from procedure site. A wide range of pneumothorax rates has been reported in the literature ... (3.5%). Ten patients developed "ex vacuo" pneumothroax following thoracentesis. The first aspiration was painless but subsequent ones became increasingly painful despite increasing frequent cause of pneumothorax (pneu-mothorax ex vacuo) after thoracentesis, which is believed to be due to paren-chymal-pleural ï¬ stulas that develop as a consequence of the reduced pleural pressure.2 In lung entrapment, insertion of a chest drain and treatment of the under-lying disease is necessary, as otherwise it Four of these were determined to be ex vacuo while 3 (1.5%) required chest tube placement. Chest tube placement is not necessary in asymptomatic patients and is unlikely to provide clinical benefit. This post is about the changing significance of a post-procedure pneumothorax in the ultrasound era. There are three causes of pneumothorax after thoracentesis. The first and most obvious cause is lung laceration by the needle or plastic catheter. This may occur if the operator inserts the needle into the lung. Knowledge of this entity is crucial for clinicians as many of these patients would be unnecessarily managed with chest tube insertions for the pneumothorax. The frequency of pneumothorax ex vacuo was significantly greater in the control group than in the manometry group. post- thoracentesis basilar pneumothorax Biplab K Saha ,1 Kurt Hu,2 Boris Shkolnik3 ... opment of the pneumothorax. This type of pneumothorax is also known as pneumothorax ex vacuo, which is a misnomer. The inpatient mortality was two times greater in the chest tube group than in the thoracentesis group (odds ratio = 2.1; value ⤠0.001, CI 1.43â312). 1 ). Figure 1: Chest X-ray showing R hydropneumothorax, post thoracentesis. Kim YS, Susanto I, Lazar CA, Zarrinpar A, Eshaghian P, Smith MI, Busuttil R, Wang TS BMC Pulm Med 2012 Dec 17;12:78. doi: 10.1186/1471-2466-12-78. Post-thoracentesis, he had a large hydropneumothorax suspicious for a pneumothorax ex-vacuo. The purpose of this study was to document in a historical cohort the incidence and clinical observations of pneumothorax ex vacuo after therapeutic thoracentesis for malignant pleural effusions in patients with underlying parenchymal lung disease. opment of a pneumothorax âex vacuoâ. Pneumothorax ex vacuo. They also found that the presence of an ex vacuo pneumothorax in the context of malignant disease is associated with a poor prognosis.13. Pneumothorax . We present a case of a 66-year-old female who presented with chronic dyspnea on exertion secondary to right-sided ⦠No serious complications occurred in either group. Insertion of a chest drain in this situation is unlikely to be beneficial as expansion of the underlying lung is restricted. Subsequent X-rays post catheter placement confirmed persistence of pneumothorax ex vacuo with no pleural apposition in all. Methods: A retrospective chart review of 214 consecutive adults who underwent outpatient therapeutic thoracentesis at our institution between January 1, 2011 and June 30, 2013 was performed. Treatment. Figure 2: Chest CT scan showing air fluid level (blue arrow) as well as pleural thickening (red arrow) consistent with lung entrapment. In our patient, the effusion was exudative by Lightâs criteria, suggesting the presence of another mechanism contributing to ⦠Of all the complications, ultrasound guidance appears to lower rates of traumatic pneumothorax after thoracentesis from a range of 5â18% with a landmark-based approach to 1â5% with an ultrasound-guided approach. A small-bore chest tube was inserted and placed on suction without any additional re-expansion of the lung or any change in his respiratory status (Figure (Figure1). It is thought that this type of ex vacuo pneumothorax occurs because (a) co-existing pleural disease precludes normal re-expansion of the lung 6 or (b) pulmonary surfactant production is insufficient due to pulmonary edema , decreased blood flow and chronic atelectasis 4,5 . However, pneumothorax ex vacuo is typically a benign condition that is not universally considered a complication but rather a physiologic sequalae of non-expandable lung and does not likely benefit from Four patients did not require chest tube placement because their pneumothorax was considered ex vacuo. ⢠Recently its said that itâs the development of pneumothorax after a thoracentesis because the lung is unable to reexpand & fill the pleural space. Unlike other iatrogenic pneumo-thoraces, it may not respond to pleural drainage and is not caused by puncture of the visceral pleura and under-lying lung. None complained of significant worsening of symptoms following thoracentesis. Keshishyan S, Revelo AE, Epelbaum O. Bronchoscopic management of prolonged air leak. In a large study of 265 large-volume thoracenteses, pneumothorax ex vacuo was estimated to occur in 3% of the subjects.4 These pneumothoraces do not typically require treat-ment as they result from a re-equilibration of intra-and extra-pulmonary pressures. Although pneumothorax ex vacuo has always occurred, its relative importance has increased as the other causes of post-procedure pneumothorax have become less common. In fact it has been reported that in ex vacuo PNX following thoracentesis, chest tube placement is not necessary in asymptomatic patients and is unlikely to provide clinical benefit . Pneumothorax following thoracentesis is an important cause of morbidity and likely results in increased length of stay for hospitalized patients. For example, bronchoscopy may be used if the pneumothorax is secondary to endobronchial obstruction with lobar or whole lung collapse. Post-thoracentesis chest imaging revealed a large hydropneumothorax suspicious for a pneumothorax ex-vacuo. Stable pneumothorax usually occurs after pleural drainage in patients with NEL, often appearing as a basilar, loculated pneumothorax without contralateral shift in the mediastinum. In a patient with MPE, the observation of pneumothorax (pneumothorax ex vacuo) after a large-volume thoracentesis or after placement of chest catheter concerned as trapped lung syndrome, especially if the configuration of the pneumothorax space simulates the distribution of pleural fluid before thoracentesis [34,35]. Emcrit.org DA: 10 PA: 50 MOZ Rank: 60. Avoiding pneumothorax ex vacuo could lead the clinician to continue futile efforts to drain the pleural effusion (i.e., with repeat thoracentesis or chest tube; Staes 2009).. This results in an unavoidable pneumothorax, which is commonly termed pneumothorax âex vacuo.â It is a fairly common finding and may occur in those with both pleural malignancy or benign pleuritis . Effusion in the post-pneumonectomy space usually accumulates ex vacuo as pleural pressure equilibrates to zero under normal physiological conditions. There subsequently remains a select group of international practitioners who are strong campaigners for routine pleural manometry during thoracentesis [22, 23]. The pulmonology team removed 2500cc of fluid, and unfortunately the patient subsequently developed re-expansion pulmonary edema and pneumothorax ex-vacuo. The patient refused to undergo thoracotomy with decortication and was treated conservatively with chest tube drainage (pigtail ⦠Pneumothorax ex vacuo is a consequence of excessively negative pressure resulting in pressure equilibration by air entry into the pleural space, either from a small visceral pleural tear or irruption of air via the catheter tract. Ultrasound. As pressure in the pleural space falls below the normal subatmospheric resting pressure of â5 to â10 cm H 2 O, the increasing transpleural gradient may entrain air from the outside along the needle track into the pleural space (creating a pneumothorax ex vacuo), cause procedural discomfort, and potentially lead to reexpansion pulmonary edema. *Again, many clinicians use these terms synonymously. Tube thoracostomy is not indicated. The unexpandable lung. Keshishyan S, Revelo AE, Epelbaum O. Bronchoscopic management of prolonged air leak. The third is termed pneumothorax ex vacuo ⦠Pneumothorax Ex Vacuo Following Thoracentesis for Persistent Pleural Effusion Katherine Florecki1*, Jordan Anaokar2, Mark Katlic1 and Yvonne Carter1 Abstract Pneumothorax ex vacuo (PEV) refers to a localized pneumothorax adjacent to a collapsed lung. thoracentesis was performed with removal of 1.3 liters of fluid. Pneumothorax ex vacuo is a benign phenomenon which rarely enlarges or leads to tension pneumothorax. Patients are asymptomatic. This should not be treated with a chest tube, because the primary problem is unexpandible lung and this will not respond to pleural drainage ( Heidecker 2006; Huggins 2010 ). Pneumothorax after partial resolution of total bronchial obstruction, 143 as a complication of lobar collapse, 144 and after therapeutic thoracentesis for malignant effusions 145 Pulmonary barotrauma such as pneumothorax (PTX) is a known complication of invasive mechanical ventilation. Patient Safety Indicators Technical Specifications Version 4.1â 2009 PSI #6 Iatrogenic Pneumothorax Page 1 Life expectancy for most patients who develop âex vacuoâ pneumothorax following therapeutic thoracentesis is short (<6 months). Our patient benefited from the small- volume thoracentesis in form of pleurX-catheter. Pneumothorax ex vacuo (âwithout vaccuumâ) is a type of pneumothorax that can develop in patients with large pleural effusions. Patients with pneumothorax ex vacuo should be given high-concentration oxygen (as long as they are not at risk of hypercapnic respiratory failure), but may require bronchoscopy to relieve the endobronchial obstruction. Pneumothorax ex vacuo: Post-thoracentesis pneumothorax in . Drainage of this pleural fluid will often result in unavoidable pneumothorax from parenchymal-pleural fistulae. Pneumothorax ex-vacuo or "trapped lung" in the setting of hepatic hydrothorax. Pneumothorax, sometimes abbreviated to PTX, (plural: pneumothoraces) refers to the presence of gas (often air) in the pleural space.When this collection of gas is constantly enlarging with resulting compression of mediastinal structures, it can be life-threatening and is known as a tension pneumothorax (if no tension is present it is a simple pneumothorax). Huggins JT, Doelken P, Sahn SA. In expert hands, pneumothorax ex vacuoemerges as the most common cause of pneumothorax following therapeutic thoracentesis (Heidecker 2006). Post-procedure imaging may be reserved for those with complicated procedures or for patients who develop symptoms or signs of pneumothorax. The principal indication for diagnostic thoracentesis is the new finding of a pleural effusion. Pleural fluid sampling permits the nature of the fluid to be determined and potential causes to be identified. ... Management of patients with âex vacuo" pneumothorax after thoracentesis. Post-thoracentesis radiographs may show air in the pleural space with the same size and shape as the prior effusion. Pleural calcification would support the suspicion of a remote process. In a large study of 265 large-volume thoracenteses, pneumothorax ex vacuo was estimated to occur in 3% of the subjects. Identification of NEL usually relies on post-procedure imaging revealing a hydropneumothorax, suggestive of a pneumothorax ex vacuo. A subsequent computed tomography (CT) chest scan demonstrated a large left pleural effusion with complete collapse of the left lung, abnormal thickening and enhancement of the posterior parietal pleura, and mediastinal shift (Figure 1). There were no episodes of bilateral pneumothoraxes. ex vacuo (âwithout vaccuumâ) is a type of pneumothorax that can develop in patients with large pleural effusions. Clinically significant re-expansion pulmonary edema is very rare, butcase reports suggest that it could be dangerous. Pneumothorax ex Vacuo. The first is caused by injury to the visceral pleura by the needle or catheter/tube or from ruptured blebs in high airway pressures. Trapped lung presents as pleural thickening and loculation without clinically active disease (Figure 20). Large volume pleural effusion leads to an increase in pleural pressure, negatively affects lung volumes and induces clinical symptoms (e.g. Post-thoracentesis chest X-ray demonstrated a decrease in: 07-08-06 left pleural effusion and left anterior pneumothorax [F igure 1B]. A chest computed tomographic scan : 119-20 revealed a septated area of ex vacuo pneumothorax with collapsed lung and a left pleural effusion J Postgrad Med 2007;53: [Figure 2]. Most pleural effusions with a depth of greater than 1 cm (as determined by lateral decubitus chest radiography or ultrasound) ⦠PNEUMOTHORAX EX VACUO ⢠It is secondary to acute bronchial obstruction. It is also seen following removal of pleural effusion by thoracentesis when the collapsed lung struggles to re-expand. Although this definition is somewhat arbitrary, we define it as such for the purposes of this topic. Radiographic features Plain radiograph. It is most commonly seen ⦠We would argue that pain was a complication. A 28 year-old gentleman presenting with 1-month history of dry cough and dyspnea was found to have a complete opacification of the left hemithorax. Pneumothorax ex vacuo: is a rare form of pneumothorax and occurs when rapid collapse of the lung produces a decrease in the intrapleural pressure. Pneumothorax ex vacuo: Post-thoracentesis pneumothorax in . Trapped lung. Pneumothorax ex vacuo. Post-thoracentesis chest X-ray demonstrated a decrease in left pleural effusion and left anterior pneumothorax B. It is generally recommended that no more than 1500cc be removed to minimize the risk of re-expansion pulmonary edema.2. Published 2010 Oct 21. doi:10.3410/M2-77 As pressure in the pleural space falls below the normal subatmospheric resting pressure of â5 to â10 cm H 2 O, the increasing transpleural gradient may entrain air from the outside along the needle track into the pleural space (creating a pneumothorax ex vacuo), cause procedural discomfort, and potentially lead to reexpansion pulmonary edema. Both may result in hydropneumothorax being present post drainage due to pneumothorax ex vacuo. Although pneumothorax ex vacuo may possibly be avoided by performing small-volume thoracentesis, it remains unclear if it is a beneficial approach as it may leave the unexpandible lung obscured. Pneumothorax Ex Vacuo There are three types of iatrogenic pneumothorax (ie, complications post-thoracentesis) seen in the ED. Careful recognition of this type of pneumothorax may save patients and physicians A decrease in size of the pneumothorax was observed in only 3 patients, none of whom had a chest tube placed. This is in accordance with the British Thoracic Society guidelines.
