aortic hiatus การใช้

• The area behind this arch is known as the aortic hiatus.
• This fibrous arch forms the anterior aspect of the aortic hiatus, through which the aorta, thoracic duct, and azygos vein pass.
• It is placed superior, anterior, and slightly left of the aortic hiatus, and transmits the esophagus, the vagus nerve, the left inferior phrenic vessels, and some small esophageal arteries from left gastric vessels.
• Structures passing through the thoracic outlet between the thorax and abdomen include the inferior vena cava and esophagus, both of which pass through the diaphragm, and the abdominal aorta and thoracic duct which pass through the diaphragm, through the aortic hiatus.
