Overall accuracy of diagnosis in the Milne study was in the range of 86-89%. In their study, the authors reviewed the postoperative chest radiographic and CT scan findings in 13 patients who underwent bilateral lung transplantation. Jeffrey A Miller, MD Associate Adjunct Professor of Clinical Radiology, University of Medicine and Dentistry of New Jersey-New Jersey Medical School; Faculty, Department of Radiology, Veterans Affairs of New Jersey Health Care System Jiwa N, Sheth H, Silverman R. Naloxone-Induced Non-Cardiogenic Pulmonary Edema: A Case Report. CT scanning is seldom used in assessing patients with NPE and ARDS, mostly because of problems in transporting and monitoring these severely ill individuals. Because pulmonary edema requires prompt treatment, you'll initially be diagnosed on the basis of your symptoms and a physical exam, electrocardiogram and chest X-ray.Once your condition is more stable, your doctor will ask about your medical history, especially whether you have ever had cardiovascular or lung disease.Tests that may be done to diagnose pulmonary edema or to determine why you developed fluid in your lungs include: 1. Radiographics. 2018:[Medline]. Septal lines indicative of interstitial edema are more frequent with cardiogenic causes than with others. [20] The initial evaluation was performed 7 days after the patient's admission. 1999 Nov. 213(2):545-52. Oxygen chambers and nasal oxygen cannulas are ideal methods for continuous … If pulmonary edema is not heart related, it's called noncardiogenic pulmonary edema. (A CT scan of NPE is shown in the image below. A morphological and quantitative analysis of lung CT scan in patients with acute respiratory distress syndrome and in cardiogenic pulmonary edema. [Full Text]. [9, 10]  Of the 11 patients, 10 had acute respiratory failure. In contrast to previous reports, pleural effusion was a frequent finding (50%) that did not worsen the patients' prognoses. Côjv°§ž$£ª. CT and chest radiography in the evaluation of adult respiratory distress syndrome. Although the peripheral infiltrate is fairly specific for lung injury, the diffuse variety is seen with equal frequency in lung injury. [Full Text]. As the edema progresses, alveolar edema is observed in a butterfly pattern characterized by the central predominance of shadows, with a clear zone at periphery lobes. 1996 Aug. 37(8):1316-22. The index was better than hemodynamic measures, and its performance equaled that of ventilatory variables in discriminating between edema types (if definitions were based primarily on hemodynamic and ventilatory variables, respectively). In its initial stages, ARDS may resemble cardiac pulmonary edema. Marik PE, Long A. ARDS complicating pustular psoriasis: treatment with low-dose corticosteroids, vitamin C and thiamine. An initial and rapid increase in pulmonary vascular pressure due to pulmonary vasoconstriction or pulmonary blood flow can lead to pulmonary microvascular injury. [16], The BLUE protocol has been reported as having a sensitivity of 97%, a specificity of 95%, a positive predictive value of 87%,  and a negative predictive value of 99% for diagnosis of acute hemodynamic pulmonary edema. About 5% of the radiographs were false positive, and 11% were false negative. Feletti F, Mucci V, Aliverti A. 4. Intensive Care Med.

[19]. There are multiple thickened septal lines seen in the periphery of the lungs. [18] Patients in the study suffered from respiratory insufficiency and bilateral, alveolar pulmonary edema, as demonstrated on chest radiographs. The latter, noncardiogenic pulmonary edema (NPE), is caused by changes in permeability of the pulmonary capillary membrane as a result of either a direct or an indirect pathologic insult (see the images below). The early signs of pulmonary edema (interstitial edema) are the septal lines (Kerley B lines), which are horizontal lines seen laterally in the lower zones. As showed in the e-Tables, the ARDS criteria adopted were based, among others, on exclusion of cardiogenic pulmonary edema (CPE). Air bronchograms were frequently seen in areas of consolidation (89%). [Medline]. Noncardiogenic Pulmonary Edema Aliye O. Bricker, MD Tan-Lucien H. Mohammed, MD, FCCP Key Facts Terminology Acute lung injury is general term for hypoxemic respiratory failure due to alveolar epithelial and capillary endothelial injury ARDS is subset of ALI Acute interstitial pneumonia (AIP) is idiopathic form of ARDS ARDS commonly defined by ratio of PaO2:FiO2 <… A reticular pattern with a striking anterior distribution is a frequent finding of follow-up CT scanning in ARDS survivors and is most strongly related to the duration of pressure-controlled, inverse-ratio ventilation. Limitations of portable roentgenography of the chest in patients with acute respiratory failure. i.v. Imaging of complications of lung transplantation. For pulmonary oedema to develop, essentially an increased intravascular hydrostatic pressure or a disturbed vascular permeability is always responsible. Large lung cysts and small cysts producing a Swiss-cheese appearance of the parenchyma were detected. Pulmonary oedema can be cardiogenic (high pressure) or non-cardiogenic (increased vascular permeability). Diagnostic value of the portable chest x-ray technic in pulmonary edema. 1986 Jul. 1987 Aug. 27(8):367-9. [Medline]. 1989 Dec. 153(6):1181-5. Anteroposterior chest radiograph shows interstitial and alveolar pulmonary edema. Assuming that the 3 levels were a representative sample of the whole lung, the authors computed lung weight from the mean CT scan number and lung gas volume. There are bilateral pleural effusions, larger on the right than the left. %PDF-1.4 A useful characteristic for differentiating cardiac pulmonary edema from NPE, as well as from pneumonia and other widespread exudates, is the amount of time it takes for the edema to develop and to vanish. Pesenti A, Musch G, Lichtenstein D, Mojoli F, Amato MBP, Cinnella G, et al. Goodman LR, Fumagalli R, Tagliabue P, et al. Imaging in acute respiratory distress syndrome. … The lowest accuracy (81%) was obtained in distinguishing chronic cardiac failure from renal failure. Al-Sofiani M, Nikolla D, Metta VV.

AJR Am J Roentgenol. The opacities were patchy (42%), homogeneous (23%), ground glass (8%), or mixed (27%). Histologically, ARDS is characterized by diffuse alveolar damage (DAD) and extravasation of protein-rich edema (Figure 1) with frequent evolution to pulmonary fibrosis. - The most common cause of noncardiovascular pulmonary edema is ARDS. Adult respiratory distress syndrome due to pulmonary and extrapulmonary causes: CT, clinical, and functional correlations. Through analysis of the CT scan number frequency distribution, the authors found the following definite patterns of distribution: Type 1 - Bimodal, with 1 mode in the normal CT scan number range, Type 2 - Unimodal, narrow distribution, with the mode in the CT scan range of water, Type 3 - Unimodal, broad distribution in the abnormal CT scan number range. The ability to discern between non-cardiogenic pulmonary edema from cardiogenic pulmonary edema is important for adequate treatment options as well as a prognostic indicator. A study by Liebman et al indicated that it is hazardous to accept a portable radiographic diagnosis of congestive heart failure as a cause of pulmonary edema. Surg Gynecol Obstet. 1993 Jul. Viral Pneumonia with consolidation confirmed with radiology. Pulmonary capillary leak syndrome secondary to influenza SARS‐CoV‐2virus infection was not previously reported. 1978 Apr. We report 2 cases. Clin Med & Res 2012; 10: 131–136. The radiographic score for congestive heart failure was correlated with the wedge pressure but not well enough to be clinically useful.

For clinical purposes, pulmonary oedema is grossly divided based on pathophysiology into cardiogenic and non-cardiogenic oedema. However, the specificity of chest radiographs, particularly portable, anteroposterior (AP) images, is low, and it may not be possible to differentiate the various causes of lung parenchymal shadowing on radiographs alone. Axial, contrast-enhanced computed tomography (CT) scan shows alveolar and interstitial pulmonary edema. Tagliabue M, Casella TC, Zincone GE, et al.

If a heart problem causes the pulmonary edema, it's called cardiogenic pulmonary edema. This, in addition to prior reports of naloxone-induced non-cardiogenic pulmonary edema, yields a Nar-anjo score of 6, indicating a probable relationship between the patient’s symptoms and the suspect drug. Radiographics. The patient was discharged with no long-term sequelae or complica- The infiltrates of cardiogenic pulmonary edema are usually diffuse, and air bronchograms are rare. Positron emission tomography with [18F]fluorodeoxyglucose to evaluate neutrophil kinetics during acute lung injury. Conventional chest radiography is readily and universally available, and it has the added advantage of portability. [Medline]. The authors concluded that the rate of FDG uptake in the lungs during lung injury reflects the state of neutrophil activation. Am J Physiol Lung Cell Mol Physiol. To avoid life-threatening complications, prompt recognition of NPE is important. 1995;165:817-820. 42 (5):686-698. (Radiographs of pulmonary edema are shown below.). [8] They identified 3 principal and 7 ancillary features; all of these were statistically significant and, in a large percentage of cases, allowed accurate determination of the cause of edema. In their report, the authors assessed the usefulness of portable chest radiographs in defining the amount of physiologic shunting and the severity of NPE. Koizumi and colleagues studied serial scintigraphic assessment of 123I MIBG lung uptake in a patient with high-altitude pulmonary edema.

Lung transplantation: indications, donor and recipient selection, and imaging of complications. Gattinoni and coauthors examined 10 patients with full-blown ARDS who were receiving mechanical ventilation with positive end-expiratory pressure (PEEP) and who underwent lung CT scanning. For many years, pulmonary edema has been seen occasionally at chest radiography in acute pulmonary embolism (, 18). Lung ultrasound is a radiation-free, noninvasive tool available at the bedside that can provide useful information on ARDS diagnosis when radiography or CT is not available. Radiologe. The clinical history of increased intracranial pressure in this ICU patient, with no increased septic markers, that guide us for non-cardiogenic pulmonary edema as the likely cause.

Novel approaches to ultrasonography of the lung and pleural space: where are we now?. The B profile associated with hemodynamic pulmonary edema,combines lung sliding with lung rockets at the 4 anterior points. Many causes of NPE exist, including drowning, acute glomerulonephritis, fluid overload, aspiration, inhalation injury, neurogenic pulmonary edema, allergic reaction, and  adult respiratory distress syndrome (ARDS). Radiographic changes consisted of bibasal (N=2) and right middle and lower (N=2) or left basal consolidation (N=1); no changes were observed in 7 episodes. 2017 Jun. Conventional chest radiographs are universally available. Can Respir J. In the Ragimakers et al study, the 2 radionuclides were used to calculate the pulmonary leak index. [16], Echocardiography may also play a role in the differentiation of cardiogenic pulmonary edema from NPE. There is pulmonary edema as evidenced by widespread bilateral … Differing constellations of these features, each characteristic of a specific type of edema, were found. A case of non-cardiogenic pulmonary edema provoked by intravenous acetazolamide. On receiver operating characteristic curves, the pulmonary leak index performed best when ARDS and hydrostatic pulmonary edema were defined only on the basis of risk factors. [Medline]. Many causes of NPE exist, including drowning, acute glomerulonephritis, fluid overload, aspiration, inhalation injury, neurogenic pulmonary edema, allergic reaction, and adult respiratory distress syndrome (ARDS). In addition, cardiogenic edema can give rise to an appearance similar to NPE on CT scans. Oxygen supplementation should be initiated at 40-70% fraction of inspired oxygen (FiO2). [Medline]. An increase in vascular permeability consequently results in edema formation, as suggested by the frequent observation of pulmonary hemorrhage in NPE (ie, the blast theory). Pleural effusion may be seen in all 3 causes. The B-line is defined using 7 criteria,  3 of which are always present: a comet-tail artifact; arising from the pleural line; moving in concert with lung sliding (when lung sliding is present). 4 (3):349-352. In general, chest radiography was inaccurate in the assessment of these complications, and CT scanning was accurate in such assessments. Infiltrates in nephrogenic pulmonary edema are classically described as having a bat-wing distribution, whereas those in lung injury tend to be more peripheral. 209:33-8. Radiographic findings lagged behind physiologic derangements. [5, 6] Herman and colleagues, however, found chest radiography to be helpful, but not definitive, in distinguishing problems after bilateral lung transplantation and found CT scanning to be excellent for the demonstration of airway problems. %Ç쏢 135(4):604-6. Three tomographic levels, specifically, apex, hilum, and base, were selected. 1. Chest Ultrasonography in Modern Day Extreme Settings: From Military Setting and Natural Disasters to Space Flights and Extreme Sports. Non-cardiogenic pulmonary edema is usually self-limiting and clinical symptoms can resolve in as early as 18-24 hours after onset. Am J Surg. Pulmonary edema is differentiated into 2 categories: cardiogenic and noncardiogenic. The highest accuracy was obtained in distinguishing capillary permeability edema from all other varieties (91%). 2004 Apr. [15], The bedside lung ultrasound in emergency (BLUE) protocol has been developed for the immediate diagnosis of acute respiratory failure. The reimplantation response (NPE due to ischemia, trauma, denervation, and lymphatic interruption) occurred in 12 patients and usually consisted of bilateral perihilar and basal consolidation. Neurogenic pulmonary edema (NPE) is a non‐cardiogenic pulmonary edema that is caused by an acute central nervous system injury and usually develops rapidly after an injury. A mixed picture with varying levels of the viral pneumonia and non-cardiogenic pulmonary oedema. If substantial improvement occurs within 24 hours, this is virtually diagnostic of cardiac pulmonary edema. 2016 May. Although several episodes of NPE resolve spontaneously, the condition may cause unexpected death among patients with epilepsy. 2015 Apr. Whether the hemodynamic changes produce a pulmonary capillary leak through pressure-induced mechanical injury to the pulmonary capillaries or whether some direct nervous system control over pulmonary capillary permeability exists remains uncertain. Tagliabue and colleagues reviewed the findings of 74 patients with ARDS who underwent chest CT scanning.

CT-findings in ARDS. According to a study by Chen and Schuster, fluorodeoxyglucose–positron emission tomography (FDG-PET) scanning may be useful for studying neutrophil kinetics during oleic acid–induced lung injury. These findings were not regularly appreciated on chest radiographs. Korzeniewski K, Nitsch-Osuch A, Guzek A, Juszczak D. High altitude pulmonary edema in mountain climbers. [Medline]. [11]. Cardiogenic pulmonary edema is a subtype of pulmonary edema where the underlying etiology is due to left ventricular dysfunction. Siddiqi TA, Hill J, Huckleberry Y, Parthasarathy S Respir Care 2014 Feb;59(2):e15-21. Raijmakers and co-investigators concluded that a 67Ga pulmonary leak index can be used in distinguishing ARDS from hydrostatic pulmonary edema. Crit Care. Milne and colleagues conducted an independent, 2-observer study of 216 chest radiographs in 61 patients with cardiac disease, 30 with renal failure or overhydration, and 28 with capillary permeability edema. Milne EN, Pistolesi M, Miniati M, et al. Share cases and questions with Physicians on Medscape consult. All but one of the patients were mechanically ventilated.

CT scanning was performed when a complication was suspected. The latter, noncardiogenic pulmonary edema (NPE), is caused by changes in permeability of the pulmonary capillary membrane as a result of either a direct or an indirect pathologic insult (see the images below). Three or four B-lines create the pattern called septal rockets, which correlate with Kerley’s lines (subpleural interlobular septa). The second examination, performed 2 months later, showed ratios of 1.39 for the right lung and 1.33 for the left lung. <> 1978 May. A case of non-car-diogenic acute pulmonary edema in a patient with poems syndrome-associated pulmonary arterial hypertension. 3. High-resolution CT (HRCT) scanning demonstrates widespread airspace consolidation, which may have predominant distribution in the dependent lung regions. 1994 May. [Medline]. The development of pulmonary edema is divided in cardiogenic and non-cardiogenic. [Medline]. Sumaira Macdonald, MBChB, PhD, FRCP, FRCR, EBIR Chief Medical Officer, Silk Road Medical Rationale: Acute non-cardiogenic pulmonary edema (ANPE) is a rare but challenging complication which occurs during the perioperative period, mainly before and after the extubation in the course of the recovery period of general anesthesia.It is characterized by increased fluid in extravascular pulmonary spaces, preventing gas exchange and further resulting in respiratory failure. Any pulmonary or extrapulmonary process that generates uncontroll… … 2002 Most patients with NPE are seriously ill and immobile, and there may be transportation problems regarding computed tomography (CT) scanning and magnetic resonance imaging (MRI) units. The other 4 criteria are almost always present: long; well-defined; erasing A-lines; hyperechoic. The ancillary features were pulmonary blood volume, peribronchial cuffing, septal lines, pleural effusions, air bronchograms, lung volume, and cardiac size. Non-cardiogenic pulmonary edema is categorized depending on the under … Breathe (Sheff). [20, 21]. Another feature that may be seen is cardiac enlargement, in cases of previous cardiac failure. The septal lines arise from the pleural surface and are typically 1 mm thick and 10 mm long; unlike blood vessels, these reach the edge of the lung. M L Storto , S T Kee , J A Golden , W R Webb American Journal of Roentgenology . Hydrostatic pulmonary edema: high-resolution CT findings. Radiographic assessment of the amount of pulmonary edema and the severity of left ventricular failure was compared with the physiologic shunt fraction, tracer-measured lung water, and pulmonary arterial wedge pressure. [Medline]. 1999 Oct. 116(4):1129-31. Please confirm that you would like to log out of Medscape. In 15 patients, CT scans provided additional information that was not obvious on bedside chest radiographs and led to a change in care for 5 patients. However, the heart may also be of normal size in cardiogenic edema after acute myocardial infarction. [Medline]. Mediastinal lymphadenopathy, common finding in patients with pulmonary edema. Ann 146(5):705-8. [13] Seven healthy subjects also were included in the study. Serial scintigraphic assessment of iodine-123 metaiodobenzylguanidine lung uptake in a patient with high-altitude pulmonary edema. Often, loculated pneumothorax (32%) was mostly anteromedial. Two major components contribute to the pathogenesis of NPE: elevated intravascular pressure and pulmonary capillary leak. With various definitions, a supranormal pulmonary leak index for ARDS had a sensitivity of 100%, while its specificity ranged from 46 to 75%. 35(3):230-4.

However, over the course of 24-48 hours following the onset of tachypnea, dyspnea, and hypoxia, ARDS becomes more widespread and uniform. The investigators speculated that the reduction of lung uptake observed in the early recovery stage might be associated with impairment in pulmonary endothelial cell metabolic function in the development of high-altitude pulmonary edema. Gattinoni L, Presenti A, Torresin A, et al. Herein we report a 35-year-old female that presented to our emergency department with non-cardiogenic pulmonary edema.
