The pneumothorax component did not change with inspiration or expiration (Fig. Ex vacuo pneumothorax is an uncommon complication of thoracentesis, but one that presents a difficult management dilemma for the interventionalist. A case of tension pneumothorax developed after placement of a tunneled pleural catheter for treatment of malignant pleural effusion in a patient with advanced lung cancer. The unexpandable lung. -How to understand difference in pneumothorax rate presented in line 93 (102 chest x-ray presented air in pleural space) and line 113 – there was rate of 9 pneumothoraces? CAS Article PubMed Google Scholar 7. PMID: 16087092. ... the rate of pneumothorax ex vacuo. Ponrartana S, Laberge JM, Kerlan RK, Wilson MW, Gordon RL. We compared preprocedural to postprocedural discomfort (using a linear analog scale … Of all the complications, ultrasound guidance appears to lower rates of traumatic pneumothorax after thoracentesis from a range of 5–18% with a landmark-based approach to 1–5% with an ultrasound-guided approach. Due to these concerns, the historical teaching has been to limit the volume of pleural fluid removed. Pneumothorax . It is also seen following removal of pleural effusion by thoracentesis when the collapsed lung struggles to re-expand. Emcrit.org DA: 10 PA: 50 MOZ Rank: 60. POST-PROCEDURE RADIOGRAPH DISCUSSION 3. Because of the patient’s debilitating symptomatology, a right-sided bedside thoracentesis was performed. Reexpansion pulmonary edema may develop as a complication of therapeutic thoracentesis. In 2 other patients small asymptomatic pneumothoraces were found in chest radiographs performed after the completion of the procedure. thoracentesis was performed with removal of 1.3 liters of fluid. Tension pneumothorax: occurs when the intrapleural pressure exceeds atmospheric pressure throughout expiration and often during inspiration. Acad Radiol. Similarly, pleural manometry has enjoyed in the past several years a regain of interest from the pulmonary community. Drainage of this pleural fluid will often result in unavoidable pneumothorax from parenchymal-pleural fistulae. Interpretation Measurement of pleural pressure by manometry during large-volume thoracentesis does not alter thoracentesis was performed with removal of 1.3 liters of fluid. Ex: Fibrosis, chest wall abnormalitis, pulm edema, obesity, plural effusion. Agustı́ AGN, Cardús J, Roca J, Grau JM, Xaubet A, Rodriguez-Roisin R. Ventilation-perfusion mismatch in patients with pleural effusion: effects of thoracentesis. It is most commonly seen … 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. 5. To determine clinical outcome in patients who developed "ex vacuo" pneumothorax following thoracentesis and to assess the benefit of chest tube placement for this complication. The diagnosis of trapped lung was made based on the presence of a hydropneumothorax after evacuation of a longstanding hepatic … Materials and methods: Forty pneumothoraces resulted from 512 therapeutic thoracentesis performed for malignant pleural effusions over a 3-year … As pressure in the pleural space falls below the normal subatmospheric resting pressure of −5 to −10 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. 1998 Apr; 170 (4):943-6. 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). Pneumothorax ex vacuo is important to recognize as a possible cause of pneumothorax following therapeutic thoracentesis. Materials and methods We retrospectively reviewed records of 282 patients who underwent 437 thoracenteses at a single institution during a 6-year period. Thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall. 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. Immediately following thoracentesis, the patient's chest X-ray showed development of a hydropneumothorax. J93.83 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. Stable pneumothorax usually occurs after pleural drainage in patients with NEL, often appearing as a basilar, loculated pneumothorax without contralateral shift in the mediastinum. When draininga large pleural effusion, the main concern is that excessive fluid removalcould lead to re-expansion pulmonary edema. The catheter placement was carried out by an experienced operator under direct ultrasound guidance, and the patient showed immediate symptomatic improvement with acute decompensation occurring several hours later. The 2021 edition of ICD-10-CM J93.9 became effective on October 1, 2020. does not require chest tube placement. 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. Sachdeva A, Shepherd RW, Lee HJ. Huggins JT, Doelken P, Sahn SA. Unexpandable lung is the inability of the lung to expand to the chest wall allowing for normal visceral and parietal pleural apposition. 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.. Effusions related to NEL also tend to be rapidly recurrent, further supporting the use of IPCs in those with symptoms. 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 They also found that the presence of an ex vacuo pneumothorax in the context of malignant disease is associated with a poor prognosis.13. Careful recognition of … Procedure: Suction-Driven Thoracentesis. Trapped lung. 13 Clinically significant re-expansion pulmonary edema is very rare, butcase reports suggest that it could be dangerous. 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 . Procedure: Suction-Driven Thoracentesis Thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall. During the last thirty years, there has been great interest in monitoring pleural pressures during therapeutic thoracentesis in an attempt to prevent the development of re-expansion pulmonary edema (REPE) and pneumothorax ex vacuo, diagnose unexpandable lung, and perhaps, predict the success rate of pleurodesis in malignant pleural effusion (MPE). ... Management of patients with “ex vacuo" pneumothorax after thoracentesis. 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. Pleural calcification would support the suspicion of a remote process. Presentation chest X-ray showed a large right pleural effusion with compressive atelectasis (Fig. Pneumothorax after partial resolution of total bronchial obstruction, 143 as a complication of lobar collapse, 144 and after therapeutic thoracentesis for malignant effusions 145 AJR Am J Roentgenol. CXRs after thoracenteses are at the discretion of the physician. 0 Figure 2: Chest CT scan showing air fluid level (blue arrow) as well as pleural thickening (red arrow) consistent with lung entrapment. Management of patients with "ex vacuo" pneumothorax after thoracentesis. Pneumothorax can be a complication of thoracentesis procedure. Incidence of trapped lung, loculated pleural effusion, and pneumothorax [ Time Frame: 1 year post-enrollment ] Trapped lung is defined as a lung that does not expand after pleural fluid drainage leaving a pneumothorax ex-vacuo or hydropneumothorax. Josephson T, Nordenskjold CA, Larsson J, et al. Hepatic hydrothorax is a major pulmonary complication of liver disease occurring in up to 5-10% of patients with cirrhosis. Pneumothorax ex vacuo (169 words) exact match in snippet view article find links to article (2005). 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. 2000;117(4):1038-1042. Life expectancy for most patients who develop “ex vacuo” pneumothorax following therapeutic thoracentesis is short (<6 months). 2). use of manometry could anticipate the development of chest discomfort during therapeutic thoracentesis. We aimed to determine the mean pneumothorax rate following thoracentesis and to identify risk factors for pneumothorax through a systematic review and meta-analysis. No serious complications occurred in either group. 01). Ponrartana S, Laberge JM, Kerlan RK, Wilson MW, Gordon RL. Thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall. Initially, the patient was diagnosed with iatrogenic pneumothorax; however, the evolution of subsequent chest X-rays is consistent with the diagnosis of … J93.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. A PTX occurring after uncomplicated thoracentesis or chest tube insertion for drainage of a pleural effusion is typically an ex-vacuo phenomenon, representing a vacuous space (ie, created by a vacuum) and not actually “air” occurring when: • It is a medical emergency that requires prompt decompression. Repeat vital signs after thoracentesis revealed: HR 105 bpm, RR 18 rpm, O2 saturation of 98% on room air. The most important consideration is to avoid unnecessary interventions (that may result in iatrogenic injury) such as inappropriate hospitalization and chest tube placement after thoracentesis when in the setting of ex-vacuo pneumothorax (basal pneumothorax on frontal chest x-ray after drainage). "Management of patients with "ex vacuo" pneumothorax after thoracentesis ". hydropneumothorax after therapeutic thoracentesis for malignant pleural effusions. The two big concerns with a large volume thoracentesis are the risks of pneumothorax ex vacuo and re-expansion pulmonary edema (REPE). 8 Manometry may be helpful during thoracentesis to help confirm diagnosis, or to prevent excessive fluid removal that increases pleuritic pain without improving respiratory status The 2021 edition of ICD-10-CM J93.83 became effective on October 1, 2020. All were independently checked by the local pleural disease lead and pleural fellow to ascertain absence of a pneumothorax ex-vacuo. 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. We report four observations of the development of pneumothorax ex-vacuo or trapped lung in the setting of hepatic hydrothorax. Pneumothorax ex vacuo: is a rare form of pneumothorax and occurs when rapid collapse of the lung produces a decrease in the intrapleural pressure. It is a benign process; chest tubes are not helpful. 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. Introduction Pneumothorax ex vacuo (“without vaccuum”) is a type of pneumothorax that can develop in patients with large pleural effusions. Figure 2: Chest CT scan showing air fluid level (blue arrow) as well as pleural thickening (red arrow) consistent with lung entrapment. Post-thoracentesis chest X-ray demonstrated a decrease in left pleural effusion and left anterior pneumothorax B. INTERPRETATION: Measurement of pleural pressure by manometry during large-volume thoracentesis does not alter procedure-related chest discomfort. Consider pneumothorax ex vacuo in your differential of pleural air after large volume thoracentesis. Indication for Xray after Thoracentesis. Consider pneumothorax ex vacuo in your differential of pleural air after large volume thoracentesis. 2005 Aug;12(8):980-6. doi: 10.1016/j.acra.2005.04.013. Post-thoracentesis chest imaging revealed a large hydropneumothorax suspicious for a pneumothorax ex-vacuo. 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). thoracentesis was performed with removal of 1.3 liters of fluid. Ponrartana S, Laberge JM, Kerlan RK, Wilson MW, Gordon RL (2005) Management of patients with “ex vacuo” pneumothorax after thoracentesis… Identification of NEL usually relies on post-procedure imaging revealing a hydropneumothorax, suggestive of a pneumothorax ex vacuo. 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. Trapped lung presents as pleural thickening and loculation without clinically active disease (Figure 20). These findings are in accord with delayed ( > 30 min) pulmonary volume re-expansion after thoracentesis with or without the coexistence of mild ex vacuo pulmonary edema. There were no episodes of bilateral pneumothoraxes. ex vacuo. This procedure is done to remove excess fluid, known as a pleural effusion, from the pleural space … Management of patients with ex vacuo pneumothorax after thoracentesis. Chest tube placement is not necessary in asymptomatic patients and is unlikely to provide clinical benefit. Finally, pneumothorax ex vacuo can occur when fluid is removed in the setting of non-expandable lung, leaving a negative pressure space. Management of patients with "ex vacuo" pneumothorax after thoracentesis. Pneumothorax ex vacuo is a rare type of pneumothorax which forms adjacent to an atelectatic lobe. Unexpandable lung is the inability of the lung to expand to the chest wall allowing for normal visceral and parietal pleural apposition. 8 Manometry may be helpful during thoracentesis to help confirm diagnosis, or to prevent excessive fluid removal that increases pleuritic pain without improving respiratory status. In these 2 last patients trapped lung was diagnosed. ... Management of patients with “ex vacuo" pneumothorax after thoracentesis. Pneumothorax, unspecified. In expert hands, pneumothorax ex vacuoemerges as the most common cause of pneumothorax following therapeutic thoracentesis (Heidecker 2006). Due to these concerns, the historical teaching has been to limit the volume of pleural fluid removed. 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. and pneumothorax ex vacuo. This type of pneumothorax is also known as pneumothorax ex vacuo, which is a misnomer. pleural space (therapeutic pneumothorax) usually relieves the pain immediately, and may allow docu-mentation of a thickened visceral pleura if a chest com-puted tomography (CT) is obtained after the procedure, as intrapleural air contrasts well with the thickened pleura (diagnostic pneumothorax).6 Pneumothorax ex vacuo Lastly, if during therapeutic thoracentesis there is an abrupt drop in PP and the patient develops chest pain or dyspnea, pleural manometry can reestablish PP in the physiological range by being able to induce pneumothorax, letting air enter into the pleural space in a controlled manner through the system itself until this is achieved. No serious complications occurred in either group. This phenomenon has been described in the pathophysiology of pneumothorax ex vacuo after thoracentesis in unexpandable lung.5 When the chest tube is clamped, the air cannot be drained from the pleural space and, other than a transient pressure spike during the cough, the pleural pressure remains unchanged and stable. Journal of Postgraduate Medicine 53.2: 119-120 (PMID: 17495380) Procedure: Suction-Driven Thoracentesis. 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. The two big concerns with a large volume thoracentesis are the risks of pneumothorax ex vacuo and re-expansion pulmonary edema (REPE). Forty pneumothoraces resulted from 512 therapeutic thoracentesis performed for malignant pleural effusions over a 3-year period. 1.5 L of thin, dark brown fluid was removed and after the procedure, the patient stated she felt much better. Woodring JH, Baker MD, Stark P (1996) Pneumothorax ex vacuo. Traditional guidelines recommend that the volume of fluid removed *Again, many clinicians use these terms synonymously. (PMID: 25946304) Khan H, Fernandez-Perez ER, Caples SM (2007) Post-thoracentesis trapped lung. A hydropneumothorax can be appreciated by the presence of a liquid-gas level when the patient is upright and a hazy opacity in a supine patient, that may obscure the pneumothorax. Causes of Respiratory Acidosis- … Petersen WG, Zimmerman R. Limited utility of chest radiograph after thoracentesis. 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]. Ponrartana S, Laberge JM, Kerlan RK, Wilson MW, Gordon RL Acad Radiol 2005 Aug;12(8):980-6. doi: 10.1016/j.acra.2005.04.013. 3. failed to demonstrate that the use of manometry could result in less chest discomfort after the procedure in a large retrospective study. Yet, unlike ultrasound, manometry remains to be widely accepted as a valuable diagnostic tool during therapeutic thoracentesis, and Pneumothorax is a rare complication of thoracentesis when performed by a skilled operator using ultrasonographic guidance. Chest. Figure 1: Chest X-ray showing R hydropneumothorax, post thoracentesis. Woodring JH, Baker MD, Stark P. Pneumothorax ex vacuo. Acad Radiol, 12(8):980-986, 01 Aug 2005 Cited by: 8 articles | PMID: 16087092 Other pneumothorax. In such cases, an underlying trapped lung could be suspected. Pneumothorax ex Vacuo. Amount drained at ultrasound-guided thoracentesis and risk of pneumothorax. A study by Dresler et al suggests that among patients who undergo thoracentesis, approximately 10% have non-expandable lung, 20% of patients who undergo therapeutic thoracentesis and 30% of those who undergo therapeutic thoracentesis for malignant pleural effusion have non-expandable lung. The most common complication of thoracentesis is pneumothorax. The majority of these may be related to pneumothorax ex vacuo, a condition in which fluid is drained from the chest, but the lung is unable to expand ... 63. Final Diagnosis: Trapped lung (pneumothorax ex vacuo) References: Albores J, Wang T. (2015) Images in clinical medicine. Although pneumothorax ex vacuohas always occurred, its relative importance has increased as the other causes of post-procedure pneumothorax have become less common. Conceptually, pneumothorax is categorized as stable or unstable. In our experience, the rate of pneumothorax is near zero when pneumothorax ex vacuo is excluded. Four of these were determined to be ex vacuo while 3 (1.5%) required chest tube placement. Pneumothorax ex vacuo Patients are mostly asymptomatic. Pneumothorax ex vacuo: a rare form of pneumothorax that occurs when rapid collapse of the lung produces a decrease in the intrapleural pressure. Chest 110:1102–1105. 1); thoracentesis was suggested and performed. Management of patients with "ex vacuo" pneumothorax after thoracentesis. Unlike spontaneous or tension pneumothoraces, pneumothorax . PubMed 64. F1000 Med Rep. 2010;2:77. 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. 20 One of the most common causes of unexpandable lung is the formation of a fibrous peel of the visceral pleura that prevents the lung from expanding. Air was Aspirated Sx: Chest pain, dyspnea, hypoxemia Multiple needle passes ... Pneumothorax, pleural effusions Scleroderma. Pneumothorax ex vacuo: Post-thoracentesis pneumothorax in . This phenomenon has been described in the pathophysiology of pneumothorax ex vacuo after thoracentesis in unexpandable lung.5 When the chest tube is clamped, the air cannot be drained from the pleural space and, other than a transient pressure spike during the cough, the pleural pressure remains unchanged and stable. Unlike spontaneous or tension pneumothoraces, pneumothorax ex vacuo does not require chest tube placement. ex vacuo (“without vaccuum”) is a type of pneumothorax that can develop in patients with large pleural effusions. Acta Radiol 2009; 50:42. 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. All available radiology was checked for complications, most notably pneumothorax. 2005 Aug; 12 … Routine monitoring with pleural manometry during therapeutic large-volume thoracentesis to prevent pleural-pressure-related complications: a multicentre, single-blind randomised controlled trial. 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). cedures in general, and thoracentesis in particular. It can manifest clinically as severe chest pain during thoracentesis or on imaging as a hydropneumothorax or pneumothorax ex vacuo after thoracentesis. 20 One of the most common causes of unexpandable lung is the formation of a fibrous peel of the visceral pleura that prevents the lung from expanding.
