Multi-slice computed tomography (CT) of the chest. Preoperative CT shows a huge mediastinal fluid collection surrounding both A) the ascending, and B) aortic arch prosthetic grafts having a diameter of 15 cm with a low density (12-18 Hounsfield Units). Postoperative CT shows omental wrapping with normal density (65-80 Hounsfield Units) around the C) the ascending, and D) aortic arch prosthetic grafts without evidence of fluid collection or infectious sequela 18 months after the operation. · NIH Open-i / PMC (Open-access (PMC))
A 48-year-old man is brought to the emergency department 1 hour after the sudden onset of chest pain and shortness of breath.
