An aortic dissection occurs when the inner and/or middle layer of the aorta is torn or split with blood flowing through. Although this disease is rare, it can be fatal especially in case of a leaky aorta with blood flowing outside the main artery. The fatality rate of this heart disorder can be lowered with early detection and proper treatment, detecting the disease at its early stage is difficult as the symptoms are similar to other conditions. An aortic dissection tends to be found in males aged 60–70 years old. Treatment option usually are medication and surgery.
An aortic dissection tends to cause symptoms which could be similar to those of a heart attack. Aortic dissection may manifest the following sign and symptoms:
Sudden severe pain in the chest or upper back and spreads to the neck or the back, together with the feeling of tearing or ripping.
Sudden severe abdominal pain
Stroke-like conditions, such as eyes suddenly getting blurry, speech impairment, and one side of the body becoming weak or unable to move
Different pulse levels in each arm or thigh
Pain in the legs
If you have any of these symptoms, seek emergency medical care immediately:
Sudden or severe chest pain
Shortness of breath
Loss of consciousness
When the aorta’s wall becomes weakened, an aortic dissection can occur. There are two types of aortic dissections, depending on the affected area of the aorta:
Type A aortic dissection: Type A aortic dissection is a life-threatening condition. It affects the part of aorta that exits the heart. The disease can also happen in the ascending aorta, which is located in the upper part of the artery and can extend into the abdominal area.
Type B aortic dissection: This type is less common than Type A, where the affected area is in the descending aorta, which is the lower aorta. The injury can also extend into the abdomen.
If you have any of these factors, you might be at risk of developing aortic dissection:
Hypertension: which is the state of having high blood pressure for a long period.
Atherosclerosis: which occurs due to an artery getting narrowed.
Aortic aneurysm: which results from a swollen and weakened artery walls.
Bicuspid aortic valve: which occurs when there is an abnormality in an aortic valve.
Aortic coarctation: which is a congenital heart disease where the aorta gets narrowed.
If you have any of these genetic conditions, you also have a risk of developing aortic dissection:
Turner syndrome: This genetic disorder can cause hypertension and other heart diseases.
Marfan syndrome: This disorder is induced by weakening connective tissues, and often occurs in people with a family history of aortic aneurysms or aortic dissections.
Other connective tissue disorders: such as Ehlers-Danlos syndrome whose symptoms include loose joints and blood vessels becoming weak, as well as Loeys-Dietz syndrome, caused by distortion of an artery in the neck or any other areas.
An aortic dissection can also be induced by a giant cell arteritis, which is an inflammatory disease affecting the large blood vessel.
The development of an aortic dissection also depends on many other factors as the following:
Sex: The aortic dissection condition can be found more often in male than female.
Age: Those that are older than 60 have a higher risk of aortic dissection.
Drug Use: Cocaine use, as it causes temporary hypertension.
Pregnancy: Despite being a rare occurrence, being pregnant can cause a woman with no illness to develop an aortic dissection.
High-intensity weightlifting: An aortic dissection can be caused by this kind of activity as it temporarily causes hypertension while you are doing it.
