    INPUT: Right - sided dual - lumen hemodialysis catheter is noted with tip terminating at the junction of the SVC and right atrium . The patient is status post median sternotomy and CABG , with multiple broken median sternotomy wires redemonstrated . Heart size is top normal . There are low lung volumes , with crowding of the bronchovascular structures and likely mild pulmonary vascular congestion . Bilateral pleural effusions are again noted , which appear loculated laterally and are similar in size when compared to the prior study . Patchy opacities at the lung bases most likely reflect atelectasis . No pneumothorax is identified . There are no acute osseous abnormalities . The mediastinal contour is unchanged with aortic knob calcifications again noted .
    OUTPUT:
    
Mild pulmonary vascular congestion with unchanged small - to - moderate sized bilateral pleural effusions with laterally loculated components . Probable bibasilar atelectasis .
