Difference between Aortic Dissection and Aneurysm

When most people think of heart ailments, they think of conditions like aortic aneurysm and aortic dissection. Though both are serious conditions, there is a big difference between the two. In this post, we’ll take a look at the key differences between these two conditions. By understanding the distinctions, you can be better equipped to seek treatment if you experience any symptoms.

What is Aortic Dissection?

Aortic dissection is a condition in which the inner layer of the aorta, the large blood vessel that carries oxygen-rich blood from your heart to the rest of your body, tears. Aortic dissection can be life-threatening and requires immediate medical attention. The most common symptom of aortic dissection is severe chest pain that may feel like a ripping or tearing sensation.

Other symptoms may include shortness of breath, back pain, and loss of consciousness. Aortic dissection can occur with no warning signs or symptoms, so it’s important to seek medical help immediately if you experience any of these symptoms. Aortic dissection is a serious condition that can be fatal, but with timely diagnosis and treatment, many people recover fully.

What is Aortic Aneurysm?

Aortic Aneurysm is a condition where there is a widening or ballooning of the Aorta, which is the large blood vessel that carries blood from the heart to the rest of the body. Aortic Aneurysms can be very dangerous as they can rupture, causing internal bleeding that can be fatal. Aortic Aneurysms usually don’t cause any symptoms until they rupture, so it’s important to get regular check-ups and screenings, especially if you have risk factors such as high blood pressure, smoking, or a family history of Aortic Aneurysm. Treatment for Aortic Aneurysm usually involves surgery to repair the aneurysm before it ruptures. If you think you may have Aortic Aneurysm, talk to your doctor right away.

Difference between Aortic Dissection and Aneurysm

Aortic dissection is a separation of the walls of the aorta, the main artery that carries blood from the heart to the rest of the body. Aneurysms are bulges in the aorta that can occur in any section of the artery. Aortic aneurysms may not cause any symptoms, but they can burst and cause life-threatening bleeding. Aortic dissections often occur in people with uncontrolled high blood pressure or other conditions that weaken the walls of the aorta.

Aneurysms can also be caused by weakened arteries. In some cases, aneurysms may grow large enough to press on nearby organs. Aortic dissections and aneurysms can both be life-threatening conditions. Aortic dissection requires emergency surgery to repair the damaged artery. Aneurysms may be treated with surgery, but small aneurysms may not require treatment.


Aortic dissection and aneurysm are both serious conditions, but it’s important to understand the difference between the two. If you think you or a loved one may be suffering from either condition, don’t hesitate to seek medical help. Early diagnosis and treatment are essential for the best possible outcome.
