Perihilar fluffy opacities on Xrays are seen in
Correct Answer: Pulmonary edema
Description: Pulmonary venous hypeension:It is caused by increased resistance to blood flow in the pulmonary veins, due to obstruction or reduced compliance within the left atrium, at the mitral valve, or within the left ventricle.It is divided into 3 grades of severity:Grade I PVH:a. Reversal of normal gravity dependent gradient of pulmonary blood flow with the diameter of upper lobar vessels greater than that of lower lobe vesselsb. Enlargement of the right superior pulmonary vein with loss of hilar angle lateral concavity of hilumc. Loss of visibility of mid and distal poions of the right descending pulmonary trunkGrade ii PVH:d. Interstitial pulmonary edemae. Pleural effusionGrade iii PVH:f. Alveolar pulmonary edema with bilateral fluffy alveolar opacitiesg.
