A tortuous thoracic aorta is serpentine in its shape or path, according to Yale University School of Medicine. The thoracic aorta is the portion of the descending aorta above the diaphragm, according to InnerBody. The descending aorta begins at the posterior of the heart toward the left of the body.Know More
The ascending aorta above the heart turns 180 degrees in the aortic arch, toward the left side of the body, before passing as the descending aorta through the thorax and abdomen, according to InnerBody.
An aorta described as tortuous on the basis of a simple chest X-ray could refer to an enlarged section of the aorta, which might represent the presence of an aneurysm, notes the American Heart Association, or it could indicate that a section of the aorta has more twists and bends than is typical, according to the Texas Heart Institute. Aortic tortuosity is not an uncommon finding in the elderly. To determine the extent of tortuosity, a simple chest X-ray is inadequate, and more advanced imaging such as computerized axial tomography or MRI scans of the chest are required.
A tortuous aorta is one of the symptoms of a rare disease known as Arterial Tortuosity Syndrome, according to the Institute of Genetic Medicine.Learn more about Human Anatomy
The normal size for an ascending aorta is approximately 33 millimeters in diameter. Because normal human anatomy varies, approximately 95 percent of the human population falls between 37 and 29 millimeters.Full Answer >
Tortuosity of the thoracic aorta is a slight twist in the normal curvature of the aorta, according to Dr. Joseph H. Roosth writing for HealthTap. Tortuosity of the thoracic aorta is normally found on a chest X-ray.Full Answer >
The thoracic cavity protects and holds the lungs, heart, trachea, esophagus, endocrine glands, thoracic aorta and the pulmonary artery. Enclosed by the ribs, breast bone and vertebral column, it is the second-largest hollow space of the human body.Full Answer >
The essential organs contained within the thoracic cavity are the lungs, the heart, part of the esophagus, the trachea, the thymus gland and the thoracic duct. There are lymph nodes within the thoracic cavity, as well as numerous blood vessels and nerves. There are three compartments within the thoracic cavity: two pulmonary cavities and the mediastinum.Full Answer >
