    INPUT: Frontal chest radiograph demonstrate interval removal of a left subclavian approach Swan - Ganz catheter . The endotracheal tube terminating in the mid thoracic trachea , enteric 2 terminating below the diaphragm and off the inferior edge of the image , a right internal jugular catheter terminating at the cavoatrial junction , left chest tube , mediastinal drains , are all unchanged in position . A left subclavian approach catheter projects over the expected location of the left subclavian vessels and clavicle , but the location is difficult to determine . It does not follow the expected course of the vessel centrally . The cardiac silhouette remains enlarged , and there are unchanged bilateral opacities , with a likely left pleural effusion .
    OUTPUT:
    
The left subclavian approach catheter projects over the expected location of the left subclavian vessels and clavicle , but the location is difficult to determine catheter does not follow the expected course of the vessels centrally .
