descending aorta - aortic displacement - hiatal hernia
A 91-year-old female patient was admitted to hospital for evaluation of transcatheter aortic valve implantation. A chest radiography showed a hiatal hernia, and the stomach and duodenum appeared in the thoracic cavity ([Fig. 1A]). The patient had severe aortic stenosis, and a contrast-enhanced thoracoabdominal computed tomography (CT) was performed to evaluate vascular structures. A contrast-enhanced CT scan of the chest in the coronal plane revealed normal diameter and non-tortuous ascending aorta ([Fig. 1B]). The descending aorta was pushed by the stomach and duodenum ([Fig. 1C]). A contrast-enhanced CT scan of the chest in the sagittal plane showed the pushed descending aorta ([Fig. 1D]). A contrast-enhanced CT scan of the chest in axial plane showed the descending aorta on the left side of the vertebra ([Fig. 1E]). The abdominal aorta travels on the left side of the vertebra ([Fig. 1F]). A successful intervention was done, and the patient was discharged from the hospital.
