<prompt> All are seen in congestive cardiac failure except:Kerly B linesProminent lower lobe vesselPleural EffusionsCardiomegaly  <response>: B i.e. Prominent lower lobe vessels In CCF Left hea failure there is cephalization of pulmonary vascularity i.e. dilatation of upper lobe constriction of lower zone vesselsQ, Kerley A lines interlobular septal thickeningQ, Kerley septal B lines, perihilar haze and pseudoeffusionQ. Radiological features of left ventricle failure congestive cardiac failure produced due to pulmonary venous hypeension. Stage I Equalization at pulmonary capillary wedge pressure 13-15 mm Hg fb cephalization of pulmonary vascularity at 16-18 mmHg PCWP. It is characterized by: - Constriction blurring of lower zone vesselsQ - Effacement of hilar angle Dilatation prominence of upper lobe vesselsQ. Exceptions to this pattern of redistribution are basal emphysema pulmonary parenchymal diseases of upper lobe. Stage 2 Interstial pulmonary edema at PCWP-19124 mm Hg occurs d t presence of fluid within peribroncho-vascular interstial tissue. It is seen as: - Peribronchial thickening cuffing indistinct vessel margins - Kerley A lines is 3-4 cm long lines of interlobular septal thickening radiating from hila to mid upper long zones.. - Kerley septal B lines i.e. sho horizontal reticulations within lateral subpleural lung bases. - Perihilar hazeQ dt hilar interstitial edema - Pseudoeffitsion dt thickened pleural fissures and back ground haze ground glass appearanceQ. Stage 3 Alveolar edema at PCWP 25 mm Hg occurs when the interstitial fluid accumulates at rates faster than it can be removed by the lymphatics. It is seen as - Bats wing appearance dt bilateral perihilar basilar air space opacification - BL small pleural effusion usually occurs when systemic venous pressure is also elevated as in right hea failure.
