What is the main cause of aortic dissection

Policy What are the causes of aortic dissection? Risk factors for aortic dissection include: Atherosclerosis (or buildup of plaque in the arteries) Certain genetic conditions like a bicuspid aortic valve Connective tissue diseases (such as Marfan syndrome) which run in families Traumatic injury after a car crash or from a high fall

Can high blood pressure cause aortic dissection?

Some people have milder pain, which is sometimes mistaken for muscle strain, but this is less common. Other signs and symptoms include: Although the exact cause of aortic dissections is unknown, doctors believe that high blood pressure is a contributing factor because it causes strain on the walls of your arteries.

What makes aortic dissection more likely?

In fact, men are twice as likely to have an aortic dissection as women. Other things that make an aortic dissection more likely include: Hardening of the arteries, or atherosclerosis. High blood pressure, or hypertension, that isn’t being controlled. A pre-existing bulging, or weakened, artery.

Can aortic dissection mimic other diseases?

Symptoms of aortic dissection may mimic those of other diseases, often leading to delays in diagnosis. However, when an aortic dissection is detected early and treated promptly, the chance of survival greatly improves. Aortic dissection symptoms may be similar to those of other heart problems, such as a heart attack.

How do you tear your aorta?

In an aortic dissection , a small tear occurs in the tunica intima (the inside layer of the aortic wall in contact with blood). Blood can enter this tear and cause the intima layer to strip away from the media layer, in effect dividing the tissue layers of the aortic wall and forming a false channel, or lumen.

What causes a dissecting aneurysm of the aorta?

Aortic dissection

  • Overview. An aortic aneurysm occurs when a weak spot in the wall of your aorta begins to bulge (left).
  • Symptoms. Aortic dissection symptoms may be similar to those of other heart problems, such as a heart attack.
  • Causes.
  • Risk factors.
  • Complications
  • Prevention.
  • The Mayo Clinic experience and patient stories.

What are symptoms of aortic tear?

Aortic tear symptoms may be similar to those of other heart problems, such as a heart attack, and may include: Sudden severe chest or upper back pain. Loss of consciousness. Weakness or paralysis.

What causes increased diameter of thoracic aorta?

There are two categories of factors that cause the aorta to become weakened and increase in diameter: 1) Internal pressure Think of blood pressure (BP) as the internal inflating pressure on this aortic “balloon.” Keeping the “inflating pressure,” i.e., blood pressure, low exerts substantial effect on slowing growth of aortic diameter.
