Aortic Dissection

14 min read

Aortic dissection is a medical emergency that occurs when a tear in the inner layer of the aorta causes blood to flow between the layers of the aortic wall. This can lead to severe complications, including death, if not treated quickly. Aortic dissection is a rare condition, but it is the most common cause of death from aortic disease.

Causes of Aortic Dissection

The exact cause of aortic dissection is not known, but it is believed to be related to a combination of factors, including high blood pressure, aortic aneurysm, connective tissue disorders, and trauma. It is more common in men than in women, and it is more likely to occur in people over the age of 65.

Diagnosis of Aortic Dissection

Aortic dissection is usually diagnosed with imaging tests, such as a CT scan or an MRI. These tests can show the tear in the aortic wall and the blood flow between the layers. Other tests, such as an echocardiogram or an angiogram, may also be used to diagnose aortic dissection.

Complications of Aortic Dissection

Aortic dissection can lead to serious complications, including stroke, heart attack, and organ damage. It can also cause aortic valve regurgitation, which is when the aortic valve does not close properly and allows blood to flow backward into the heart. If left untreated, aortic dissection can be fatal.

Prevention of Aortic Dissection

The best way to prevent aortic dissection is to manage any underlying conditions, such as high blood pressure or aortic aneurysm. It is also important to avoid activities that can cause trauma to the aorta, such as contact sports or heavy lifting.

Symptoms

Common Symptoms of Aortic Dissection

The most common symptom of aortic dissection is a sudden, severe pain in the chest or back. This pain may be described as a tearing, ripping, or stabbing sensation. It may be localized to one area or may radiate to other parts of the body. Other symptoms may include:

  • Shortness of breath
  • Lightheadedness or dizziness
  • Weakness or numbness in the arms or legs
  • Rapid or irregular heartbeat
  • Clammy or sweaty skin
  • Loss of consciousness

If you experience any of these symptoms, seek medical attention immediately. Aortic dissection is a medical emergency and can be fatal if not treated promptly.

Causes

Risk Factors

There are several risk factors that can increase the likelihood of developing aortic dissection. These include:

  • High blood pressure: High blood pressure can cause the walls of the aorta to weaken, making it more likely to tear.
  • Atherosclerosis: Atherosclerosis is a condition in which plaque builds up in the arteries, making them more prone to tearing.
  • Connective tissue disorders: Certain connective tissue disorders, such as Marfan syndrome, can weaken the walls of the aorta and make it more likely to tear.
  • Trauma: Trauma to the chest or abdomen can cause the aorta to tear.
  • Drug use: Certain drugs, such as cocaine, can increase the risk of aortic dissection.

Prevention

The best way to prevent aortic dissection is to reduce the risk factors. This includes controlling high blood pressure, managing atherosclerosis, avoiding trauma to the chest or abdomen, and avoiding drug use. It is also important to be aware of the signs and symptoms of aortic dissection, which include chest pain, shortness of breath, and dizziness.

If you are at risk for aortic dissection, it is important to talk to your doctor about ways to reduce your risk. Your doctor may recommend lifestyle changes, such as quitting smoking, eating a healthy diet, and exercising regularly. They may also recommend medications to help control your blood pressure or other risk factors.

Getting a Diagnosis

Computed Tomography (CT) Scan

A CT scan is a type of imaging test that uses X-rays to create detailed images of the body. It is often used to diagnose aortic dissection because it can detect the tear in the aorta and any other complications that may be present. During a CT scan, the patient lies on a table and is moved through a large doughnut-shaped machine. The machine takes multiple X-ray images of the body from different angles, which are then combined to create a detailed 3-dimensional image of the aorta.

Magnetic Resonance Imaging (MRI)

An MRI is another type of imaging test that uses powerful magnets and radio waves to create detailed images of the body. It is often used to diagnose aortic dissection because it can detect the tear in the aorta and any other complications that may be present. During an MRI, the patient lies on a table that is moved into a large tube-shaped machine. The machine then takes multiple images of the body from different angles, which are then combined to create a detailed 3-dimensional image of the aorta.

Echocardiography

Echocardiography is a type of imaging test that uses sound waves to create images of the heart and its surrounding structures. It is often used to diagnose aortic dissection because it can detect the tear in the aorta and any other complications that may be present. During an echocardiogram, the patient lies on a table and a technician places a device called a transducer on the chest. The transducer sends sound waves into the chest, which bounce off the heart and create an image of the aorta.

Electrocardiography (ECG)

An ECG is a type of test that measures the electrical activity of the heart. It is often used to diagnose aortic dissection because it can detect any changes in the heart’s electrical activity that may be caused by the tear in the aorta. During an ECG, the patient lies on a table and electrodes are placed on the chest. The electrodes measure the electrical activity of the heart and create a graph that can be used to diagnose aortic dissection.

Chest X-Ray

A chest X-ray is a type of imaging test that uses X-rays to create images of the chest. It is often used to diagnose aortic dissection because it can detect any changes in the size or shape of the aorta that may be caused by the tear. During a chest X-ray, the patient lies on a table and an X-ray machine is used to take images of the chest. The images are then used to diagnose aortic dissection.
