descending aorta
There are several reasons an aorta could be enlarged. Significant ones include hypertension, diseases of elastic tissue (including Marfan's syndrome), and syphilitic aortitis (due to long-standing infection with syphilis)
Arteries. Or you might mean the aorta, the large artery coming directly out of the heart with others brancing from it.
The Aorta is one of the hearts blood vessel's Have you ever seen an old water pipe that has a buildup around the inside surface of the pipe consisting of rust calcium and other rubbish which reduces its ability to let water through? well the same thing can happen with the blood vessels as a result of age diet or both.
Do you mean the "Celiac artery"? if so, its an artery that originates from the abdominal aorta just below the diaphragm and branches into the left gastric artery and the common hepatic artery and the splenic artery.

descending aorta
having may bends and twists....it is often used to describe the course an artery takes...having a tortuous course enables the artery to "feed" an area thoroughly with blood.
It pertains to the thorax... But you can use it as a thoracic spine, thoracic surgery, thoracic cavity, thoracic outlet syndrome, thoracic spine pain, thoracic vertebrae, thoracic medicine, thoracic surgeons, thoracic strains, sprain thoracic, or thoracic spine disorder; it's pretty self explanatory.
The thoracic cavity in a fetal pig houses vital organs such as the heart and lungs. It provides protection and support for these organs while allowing them room to function properly. Additionally, the thoracic cavity is essential for breathing and circulation of oxygenated blood throughout the body.
Tortuous means twisting, winding, or excessively complicated. It is often used to describe a path, route, or process that is not direct or straightforward.
The term 'unremarkable' when used in medical terminology refers to nothing out of the ordinary. The term unremarkable aorta on an MRI reading would mean there is nothing to be concerned about with the aorta, there is nothing out of the ordinary.
The humorous or mildly sarcastic use of words to imply the opposite of what they normally mean
Probably an Iota of evidence. The smallest amount of evidence. The Aorta is the largest artery leading from the Heart.
I would like to ask meaning of thoracic disc margins have earlydegeneratitive lipping?
Aortostenosis means narrowing of the aorta.
DefinitionA thoracic aortic aneurysm is a widening (bulging) of part of the wall of the aorta, the body's largest artery.Alternative NamesAortic aneurysm - thoracic; Syphilitic aneurysm; Aneurysm - thoracic aorticCauses, incidence, and risk factorsThoracic aneurysms most often occur in the descending thoracic aorta. Others may appear in the ascending aorta or the aortic arch.The most common cause of a thoracic aortic aneurysm is hardening of the arteries (atherosclerosis).Other risk factors include:Connective tissue disorders such as Marfan syndromeHaving high blood pressure for a long timePrevious dissection of the aortaSyphilisTrauma such as falls or motor vehicle accidentsSymptomsMost patients have no symptoms until the aneurysm begins to leak or expand. Chest or back pain may mean sudden widening or leakage of the aneurysm.Signs and testsThe physical examination is often normal. Most nonleaking thoracic aortic aneurysms are detected by tests -- usually a chest x-ray or a chest CT scan -- run for other reasons. A chest x-ray and chest CT scan show if the aorta is enlarged. A chest CT scan shows the size of the aorta and the exact location of the aneurysm.An aortogram (a special set of x-ray images made when dye is injected into the aorta) can identify the aneurysm and any branches of the aorta that may be involved.TreatmentThe treatment depends on the location of the aneurysm.For patients with aneurysms of the ascending aorta or aortic arch, surgery to replace the aorta is recommended if the aneurysm is larger than 5 - 6 centimeters. The aorta is replaced with a fabric substitute.This is major surgery that requires a heart-lung machine. If the aortic arch is involved, a specialized technique called "circulatory arrest" may be necessary. This involves a period without blood circulation while the patient is on life support.There are two options for patients with aneurysms of the descending thoracic aorta. If the aneurysm is larger than 6 centimeters, major surgery is done to replace the aorta with a fabric substitute.Endovascular stenting is a less invasive option. A stent is a tiny metal or plastic tube that is used to hold an artery open. Stents can be placed into the body without cutting the chest.Instead, tiny, hollow tubes called catheters are inserted into the groin area. The stent is passed through the catheter and into the area of the aneurysm. Not all patients with descending thoracic aneurysms are candidates for stenting, however.Expectations (prognosis)The long-term prognosis for patients with thoracic aortic aneurysm is determined by other medical problems such as heart disease and diabetes, which may have caused or contributed to the condition.ComplicationsSerious complications after aortic surgery can include:BleedingGraft infectionHeart attackIrregular heartbeatKidney damageParalysisStrokeDeath soon after the operation occurs in 5 - 10% of patients.Complications after aneurysm stenting include damage to the leg, which may require another operation.Calling your health care providerTell your doctor if you have:A family history of connective tissue disordersChest or back discomfortPreventionTo prevent atherosclerosis:Control your blood pressure and blood lipid levels.Do not smoke.Exercise regularly.ReferencesSafi HJ, Estrera AL, Miller CC 3rd, Azizzadeh A, Porat EE.
