Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left internal central jugular venous catheter terminates in the lower superior vena cava . There is no pneumothorax . The patient remains intubated . The endotracheal tube terminates about 3 cm above the carina . An orogastric tube courses into the stomach , its termination point not imaged , however . Lung volumes are low and there is persistent retrocardiac opacification that is not specific , although typical for atelectasis . Etiologies such as pneumonia or aspiration are also possible in addition to probable coinciding pleural effusion . The pulmonary vascularity appears prominent along each hilum and indistinct suggesting vascular congestion that has somewhat worsened .
    OUTPUT:
    
1 . Status post left internal jugular venous line placement , terminating in the superior vena cava ; no pneumothorax . 2 . Persistent opacification of the left lung base , probably including a pleural effusion . 3 . Findings suggesting vascular congestion , which has increased .
