The large left pleural effusion has resolved after placement of a left chest
 tube and pleural drain. There is a small to moderate loculated left basilar
 pneumothorax. There is probably no right-sided pleural effusion. The
 cardiomediastinal silhouette is stably mildly enlarged. Aortic arch stent
 graft projects in unchanged position. There is no focal consolidation or
 pulmonary edema.
