These lines are the thickened, edematous interlobular septa. [pubs.rsna.org] Diagnosis is based on bronchoalveolar lavage, although characteristic x - ray and laboratory test abnormalities occur. Kerley A lines These are longer (at least 2cm and up to 6cm) unbranching lines coursing diagonally from the hila out to the periphery of the lungs. a nd c are normal and b and d represent thickened interlobular septa in a patient with congestive heart failure. (1977-1998) The Kerley special – A keen sportsman, particularly shooting, fishing and golf, Kerley designed his eponymous fly ‘the Kerley special’, useful for salmon, trout and sea-trout.After Kerley… B and C lines are shorter, with B lines tending to take on a parallel, ladder-like appearance.

Synonym(s): costophrenic septal lines They are typically seen as a ladder up the side of the lungs beginning at the costophrenic angle. They are suggestive for the diagnosis of congestive heart failure, but are also seen in various non-cardiac conditions such as pulmonary fibrosis, interstitial deposition of heavy metal particles or carcinomatosis of the lung. © 2017 Elliot K. Fishman, MD. This may be because of lymphatic engorgement or edema of the connective tissues of the interlobular septa.

These thin lines of 1-2 cm are virtually always at the lungs bases and at the lung periphery lying perpendicular to the pleural surface to which they contact. Elas denotam septos interlobulares espessados e edematosos, muitas … They are located peripherally in contact with the pleura, but are generally absent along fissural surfaces. Fine interstitial lines at both bases, greater on the right consistent with interlobular septal thickening. Kerley B lines (thickened interlobular septa) are much spoken about as a medical student, but less commonly observed than one might expect given the volume of cardiac failure patients. They are named after Irish neurologist and radiologist Peter Kerley. They usually occur when pulmonary capillary wedge pressure reaches 20-25 mmHg. Upper lobe venous distension in keeping with pulmonary venous hypertension. These thin lines of 1-2 cm are virtually always at the lungs bases and at the lung periphery lying perpendicular to the pleural surface to which … Kerley lines are a sign seen on chest radiographs with interstitial pulmonary edema. Kerley B lines in the lung apex were present in 81% and 76% of the cardiac and renal groups, respectively, which was significantly more than in the ILD group (26%, p <0.0001). Linhas B de Kerley As linhas B de Kerley (setas) são linhas horizontais na periferia do pulmão que se estendem até a superfície pleural. These are the well known Kerley lines, often spoken about but rarely seen. In the insufficiency group, Kerley B lines were distributed more homogenously throughout the lungs compared with the ILD group in which they increased in amount from 32% in the upper lobe to 90% in the lower lobe. Kerley lines are a sign seen on chest radiographs with interstitial pulmonary edema. Kerley lines – Types A, B and C (1933 and 1951); Couch Kerley Travelling Professorship (1972 onwards); Sir Peter Kerley lectures. Kerley lines are described as types A, B or C. 1. They are named after Irish neurologist and radiologist Peter Kerley.[1][2]. These lines represent interlobular septa, which are usually less than 1 cm in length and parallel to one another at right angles to the pleura.They are located peripherally in contact with the pleura, but are generally absent along fissural surfaces. Kerley's B lines, which reflect thickening of the subpleural interstitial compartment, typically are about 1 cm in length and 1 mm in thickness and usually found in the periphery of the lower lobes, abutting the pleura. They are 1-2 cm long horizontal lines which meet the pleura at right angles. Kerley B lines These are short parallel lines at the lung periphery. The video will describe kerley B lines on a chest x-ray. Kerley B lines and interstitial edema can be seen in patients with acute MR or progressive LV failure.1 Electrocardiography. It is one of the signs of congestive heart failure. They are thin linear pulmonary opacities caused by fluid or cellular infiltration into the interstitium of the lungs. Kerley B lines are short horizontal white lines seen in chest X-ray produced by distended interlobular septa. Kerley A lines are less commonly seen than Kerley B lines. They are caused by distension of anastomotic channels between peripheral and central lymphatics of the lungs. Medical Eponyms.
