Patients may also give a history of recently worsening chronic congestive heart failure symptoms such as worsening dependent edema, orthopnea, and paroxysmal nocturnal dyspnea. Some patients need diet and lifestyle modifications. Quinn, in Encyclopedia of Respiratory Medicine, 2006. Before alveolar flooding, plain chest radiographs typically show distended vascular shadows (particularly in the upper lung fields), enlargement and loss of definition of hilar structures, development of septal lines (Kerley lines) (Fig. … Heart failure is a pathophysiological state in which cardiac output is insufficient to meet the needs of the body and lungs. Drug and alcohol use: Mild cardiomegaly caused by excess drug or alcohol use may also resolve once you stop . Potential respiratory exposures within the days before onset of disease have been reported (e.g., cave exploration, heavy dust inhalation, inhalation of smoke), suggesting that exposure to inhaled contaminants or any nonspecific injurious agent may trigger the disease. For hydrostatic reasons, perivascular edema is greatest in the gravitationally dependent regions, and the normal tethering action of the lung is therefore less in this region. Because the radiographic signs of interstitial and alveolar edema are determined by gas and blood volumes and their distribution in the lungs in addition to the presence of edema, the recognition and quantitation of edema are not precise, and the radiographic appearance of edema is strongly influenced by the lung volume at the time the film is made. Correlation with clinical and laboratory data is required to confirm the diagnosis. Lymphangitic spread of metastasis presents with Kerley lines, discrete nodules, and linear shadows, denoting a reticulonodular interstitial pattern of pulmonary disease. Because pneumonia is the most common cause of ALI, there also may be focal consolidation with air bronchograms. American Journal of Respiratory and Critical Care Medicine 149: 818–824. Kerley B lines may be also present. Chronic heart failure (CHF) is a clinical syndrome resulting in reduced cardiac output as a result of impaired cardiac contraction. In addition, there may be signs of interstitial edema, including fine reticular opacities, interlobular septal thickening (Kerley lines), perihilar haze, and peribronchial thickening. Electrocardiogram demonstrated normal sinus rhythm. His chest x-ray showed cardiomegaly with suggestion of Kerley B lines . In the absence of other radiologic or clinical features of the common causes of pleural effusion with cardiac enlargement, this diagnosis may be considered. Risk Factors for SARS-CoV-2 in a Statewide Correctional System B.S. Once the magnitude of pulmonary edema is sufficiently severe to lead to persistent airway closure or alveolar flooding, it is very difficult to separate edema, atelectasis, and inflammation on chest radiographs. Multiple triggers can cause an acute decompensation of preexisting heart failure but the condition may also occur suddenly in patients with no previous history of the condition (de novo heart failure). Images in Clinical Medicine from The New England Journal of Medicine — Kerley's A, B, and C Lines. By continuing you agree to the use of cookies. These lines are the thickened, edematous interlobular septa. Hugh O'Brodovich MD, in Kendig's Disorders of the Respiratory Tract in Children (Ninth Edition), 2019. The pleural effusions resulting from congestive heart failure may be bilateral or unilateral. We use cookies to help provide and enhance our service and tailor content and ads. M.A. Particular attention should be paid to electrocardiographic signs of ischemia or infarction such as ST segment elevation, severe ST segment depression, new Q waves, or a new left bundle branch block. The chest x-ray initially may show only subtle reticular or ground-glass opacities, often with Kerley B lines. Medications may help manage issues like parasites and cancers. Paul Stark, in Goldman's Cecil Medicine (Twenty Fourth Edition), 2012. Unilateral effusions are usually on the right. Methotrexate and Azathioprine were discontinued. The chest radiograph may show only bilateral interstitial edema, but most likely it will demonstrate areas of alveolar filling. The histopathologic features of IAEP include acute and organizing diffuse alveolar damage together with interstitial alveolar and bronchiolar infiltration by eosinophils, intraalveolar eosinophils, and interstitial edema. The higher contrast resolution and fewer blind spots make CT the most sensitive imaging technique for detecting pulmonary metastasis. A history of dietary indiscretion is common in patients with an acute exacerbation of chronic congestive heart failure. Other laboratory tests should be directed at potential causes of ALI. The pericardial effusion may be confirmed with ultrasound as an alternative to CT. Another potential advantage of pulmonary artery catheterization is that the hemodynamic data may be useful in guiding fluid and vasopressor therapy. Any combination of additional clinical information indicating the development of chest pain, hemoptysis, sudden shortness of breath, pleural friction rub, decreased arterial Po2, or thrombophlebitis should be considered evidence for pulmonary embolism and thus would indicate more definitive evaluation.396. Severe hypoxemia may be present, with most patients fulfilling diagnostic criteria for acute lung injury (including a Pao2/Fio2 ratio of 300 mm Hg or less) or for ARDS (Pao2/Fio2 ratio of 200 mm Hg or less), with mechanical ventilation necessary in most of them. Most patients with acute pulmonary edema of any cause will present with dyspnea in which case the history of present illness should focus on dyspnea severity, time of onset, pace of onset, and associated symptoms. The Kerley lines represent interlobular sheets of abnormally thickened or widened connective tissue that are tangential to the x-ray beam (Fig. The combination of cardiomegaly, pulmonary vascular changes, interstitial or alveolar edema, and pleural effusion is almost certainly diagnostic of congestive heart failure. The vast majority of cases of hydrostatic pulmonary edema are of cardiac origin. Kerley B lines represent interlobular lymphatics which have been distended by fluid or tissue. The past medical history should focus on prior history of coronary artery disease, valvular heart disease, hypertension, or cardiomyopathy. The B lines are characteristic of subacute and chronic left ventricular failure (Chapter 58), mitral valve disease (Chapter 75), lymphangitic carcinomatosis, viral pneumonia, and pulmonary fibrosis (Chapter 92). Treatment includes sodium restriction, diuretics, and surgery for severe cases. Likewise, creatine phosphokinase-MB (CPK-MB) and troponin levels are useful in patients with suspected cardiogenic pulmonary edema to rule out myocardial infarction. Abnormal radiographic findings may occur less than 2 years after normal radiographic studies (see Fig. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. The classic Kerley lines are made by the thickening of the interlobular septa that carry the lymphatics (Kerley B lines are short thin lines, 1.5 to 2cm in length, seen in [] Peribronchial cuffing (box) and kerley lines are seen (arrow). In about 80% of individuals with H… Lymphangitic carcinomatosis with hilar adenopathy. In addition, hypoxia and sepsis may cause a metabolic acidosis. Nodular shadows were present bilaterally, the largest measuring 18 mm. By definition, arterial blood gas analysis will demonstrate significant hypoxia and intrapulmonary shunt. These are the well known Kerley lines, often spoken about but rarely seen. Prominence of the left atrium without left ventricular enlargement, in combination with fine reticular opacities and prominence of upper lobe vessels, strongly suggests mitral valve disease.659 A clinical history of rheumatic fever and a murmur indicating mitral stenosis should be sufficient to confirm the diagnosis. Patients with acute cardiogenic pulmonary edema may have sudden, severe dyspnea. If only interstitial edema is present, there may be evidence of apical vascular engorgement (so-called vascular redistribution), septal or Kerley's lines, and decreased definition of smaller blood vessels and bronchial structures (perivascular and peribronchial cuffing). Acute heart failure is the rapid onset or worsening of heart failure symptoms, and it is a common cause of hospitalization in older patients. Although recovery may occur without corticosteroid treatment, corticosteroid treatment usually is given for 2 to 4 weeks, with a starting dose of oral prednisone … They are identifiedas thin horizontal lines usually seen in the costophrenic angles, not being longer than 2cms in length and touching the pleural surface. All these causes of interstitial edema, except mitral stenosis and pulmonary veno-occlusive disease, are acute or recurrent processes; the pattern tends to be transient and changes rapidly. Your doctor may suggest treatment with antiviral medications. Kerley lines are a sign seen on chest x-rays with interstitial pulmonary edema. These lines run perpendicular to the pleura. Long-term treatment … A changing course can be ascertained by examining old examinations and obtaining serial examinations. Air bronchograms may be observed in severe edema. The finding of BAL fluid eosinophilia usually is sufficient, with differential counts greater than 25%, to obviate the need for lung biopsy; bacterial cultures of BAL fluid are sterile. These cardiovascular changes include cardiomegaly, prominence of upper-lobe vessels, constriction of lower-lobe vessels, and prominent hilar vessels. Chronic renal failure is another cause of pulmonary edema with associated pleural effusions that is usually confirmed by correlation with the clinical history. In these images. As mentioned above, acute pulmonary edema is often associated with an acute coronary event, so an electrocardiogram should be performed in all patients with suspected acute cardiogenic pulmonary edema. Isolated alveolar (about 25% of cases) or reticular (about 25% of cases) opacities may also be observed. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Thus, the physical examination in suspected ALI patients should be directed toward determining whether the patient's edema can be explained by elevated left atrial pressure and whether the patient has one of the potential causes of ALI.

The plain chest radiograph is the most practical laboratory study available for the detection of pulmonary edema.85,86 Disadvantages are that chest radiographs are insensitive to small changes in lung water and are only semiquantitative.1 An additional limitation is that chest radiographs are not consistently helpful in distinguishing increased pressure edema from increased permeability edema.85,87 These disadvantages are offset by the advantages that chest radiographs are noninvasive, inexpensive, easily repeatable, readily available, and free of serious side effects (apart from a small amount of radiation). Kerley B lines can be appreciated at the bases. Blood levels of B-type natriuretic peptide (BNP) are useful in emergency department patients with dyspnea and suspected cardiogenic pulmonary edema, however, their diagnostic accuracy in inpatients is unproven. In cardiogenic pulmonary edema, the heart silhouette is often enlarged. Cavitation is present in 6% to 7%20 and is more common with squamous cell carcinoma than adenocarcinoma. Patients with IAEP often are admitted to the intensive care unit. These are horizontal lines less than 2cm long, commonly found in the lower zone periphery. These criteria identify a patient population with hypoxemia and bilateral infiltrates on chest radiograph whose condition cannot be explained by increased left atrial pressure (noncardiogenic). Treatment options for a patient with Kerley lines depend on the cause. Table 2. Radiographs of other skeletal sites may reveal bone destruction, as in Figure 25-37. Kerley B lines are horizontal linear opacities, 1 to 2 cm in length, in contact with the pleural surface. When renal failure is the cause of pleural effusions, the associated congestive heart failure is secondary to fluid overload. a nd c are normal and b and d represent thickened interlobular septa in a patient with congestive heart failure. They are thin linear pulmonary opacities caused by fluid or cellular infiltration into the interstitium of the lungs. Lymphangitic spread of metastasis presents with, Michael A. Matthay MD, John F. Murray MD, in, Murray and Nadel's Textbook of Respiratory Medicine (Sixth Edition), Before alveolar flooding, plain chest radiographs typically show distended vascular shadows (particularly in the upper lung fields), enlargement and loss of definition of hilar structures, development of septal lines (. Kennedy et al. Although most of the radiographic signs of pulmonary edema are nonspecific, improved radiographic techniques in conjunction with improved understanding of the pathophysiology of pulmonary edema have enhanced the usefulness of the chest roentgenogram in the diagnosis of pulmonary edema. Calcification is unusual unless the metastasis is from osteosarcoma or chondrosarcoma. It most often accompanies carcinoma of the lung, breast, stomach, and pancreas.1,13,46, Michael A. Matthay MD, John F. Murray MD, in Murray and Nadel's Textbook of Respiratory Medicine (Sixth Edition), 2016. A history of a current or recurrent malignant neoplasm should suggest metastatic pleural and pericardial effusions. Sara Samoni, Luis Ignacio Bonilla-Reséndiz, in Critical Care Nephrology (Third Edition), 2019, Lung comet-tails are ultrasound artifacts generated by thickened subpleural septa; they can be considered as ultrasonographic corresponding to the Kerley lines at CRX and have been validated recently for the semiquantification of pulmonary congestion.38 In patients with heart failure, the number of lung comet-tails correlates with more traditional tools in diagnosing and monitoring resolution of pulmonary congestion.39,40 A recent study by Pivetta et al. The respiratory examination is characterized by the presence of wet rales, possible extending up to the apices of the lung. In ARDS, there is more likely to be a patchy peripheral distribution of edema and a paucity of such findings as septal lines and peribronchial cuffing. 25-37 to 25-42).16,19,53 Nodules tend to involve the basal portions of lungs, possibly related to preferential blood flow.16 Larger lesions are termed cannonball metastasis. Pulmonary embolism as a cause of pleural effusions is a more difficult diagnosis to confirm.82 Right-sided heart enlargement and pleural effusions may be suggestive of embolism. Chest radiography is valuable in diagnosing pulmonary edema. Edema first spreads through the bronchovascular interstitium and later through the septal interstitium, but Kerley B lines are an infrequent observation in patients with congestive heart failure. 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. A unilateral solitary presentation suggests a primary lesion, such as bronchogenic carcinoma. Echocardiography may be very helpful in determining the etiology of pulmonary edema. ). When alveolar flooding occurs, confluent parenchymal opacities develop. CARDIOGENIC V/S NON CARDIOGENIC EDEMA cardiogenic Non-cardiogenic Patchy infiltrates in bases Homogenous pluffy Effusions + shadows Kerley B lines + Effusions – Cardiomegaly + Kerley B lines – Pulmonary vascular Cardiomegaly – redistribuition No pulm.vascular Excess fluid in alveoli redistribuition Protein,inflammatory cells,fluid Currently, its diagnosis is based on a set of criteria as set forth by the American–European Consensus Conference on Acute Respiratory Distress Syndrome (see Table 2) (seeACUTE RESPIRATORY DISTRESS SYNDROME). 25-38). Blood eosinophilia usually is lacking at presentation, and the diagnosis of eosinophilic lung disease may not be considered on admission. Treatment: Management approach mortality is decreased with angiotensin-converting enzyme inhibitors (ACE-inhibitors) or angiotensin II receptor blockers (ARBs), β-blockers, and spironolactone or eplerenone ; Conservative avoid excessive salt in the diet. The progressive recruitment of connective tissue spaces by edema fluid in both cardiac and renal disease gives rise to hilar blurring, peribronchial cuffing, and a hazy pattern of increasing lung density. A reticular or latticelike pattern also may be present and is more common inferiorly in an upright individual. Current diagnostic criteria are listed in Box 49-6. CT depicts more accurately the extent of the disease, along the middle mediastinal structures and the involvement of paratracheal, subcarinal and pulmonary hilar areas, with better demonstration of calcifications, not usually obvious on routine X-rays [ 7 , 18 , 19 ] . Acinar shadows, often confluent and creating irregular, patchy increases in lung density that obscure vascular markings, indicate the presence of alveolar edema. Eosinophilia also may be found in pleural effusion or sputum samples. Kerley's C lines, which are rarely diagnosed by radiologists, result from thickening of the lung parenchymal interstitium and form a reticular pattern on chest radiographs. The term "congestive heart failure" is often used, as one of the common symptoms is congestion, or build-up of fluid in a person's tissues and veins in the lungs or other parts of the body. Tachypnea, tachycardia, and crackles are present on examination. This acute pneumonia develops in previously healthy people, with possible respiratory failure, and may be misdiagnosed as infectious pneumonia or acute respiratory distress syndrome (ARDS). Chronic Kerley B lines may be ca… More severe cases may show extensive consolidation of both lungs. These are more properly referred to as septal lines. Pulmonary edema is differentiated into 2 categories: cardiogenic and noncardiogenic. The peripheral blood eosinophil count often rises over a few days during the initial course of disease—an evolution suggestive of the diagnosis. Complete clinical and radiologic recovery occurs rapidly after initiation of corticosteroids, with no relapse (in contrast with ICEP).
