What Is the Aorta?
The aorta is the main blood vessel in your body. It starts in your chest where it comes off the heart and sends branches to your arms and head. It travels through your chest next to the spine and then enters your abdomen.
In the abdomen there are typically five branches of the aorta. Two that give blood to our liver, stomach, and intestines; another two that deliver blood to each kidney; and a smaller branch that gives blood to the large intestine.
After the kidney branches come off, called renal arteries, there is normally a fairly straight part of the aorta before it divides into two branches to supply blood to our legs and pelvis. The straight section of the aorta before it divides is the most common place in our bodies for an aneurysm to develop.
What Is an Aortic Aneurysm?
The word aneurysm means any place where the blood vessels grow larger than is typical, and they can happen anywhere. Aortic aneurysms can happen anywhere in the aorta and the different locations have different treatment and screening strategies.
Health care providers diagnose an aortic aneurysm often during a screening for something else. Sometimes surgery may be the next step but often we can monitor the aneurysm. When we consider whether or not to repair an aneurysm, we look at both the size, which is different depending on where in the aorta the aneurysm is located, and what other medical problems a person has.
It is important to see a specialist and decide on the best treatment. Because the aorta is the main blood vessel in the body, if we don't treat the aneurysm, it can cause symptoms and may even be life threatening.
What Is an Aortic Dissection?
All blood vessels in the body are made of layers. The arteries, those blood vessels that deliver blood to our organs, have three layers. A dissection happens when the layers separate or come apart. This can happen in a very specific spot in the blood vessel, or it can affect a long section of the blood vessel.
Dissections often occur because of high blood pressure but trauma, like a car accident, can also cause them. Like other types of aortic disease, we treat a dissection depending on where in the aorta it happens and what other medical problems a patient has; however, a dissection is almost always an emergency.
It may require immediate surgical or medical treatment because the separated layers can block blood flow to branch vessels, including the heart and brain, or cause severe pain
Aortic Dissection
An aortic dissection often becomes a chronic problem. To manage this, you should get treatment by a specialist even after the initial treatment.
Penetrating Aortic Ulcer & Aortic Hematoma
Special subtypes of aortic dissections include penetrating aortic ulcers (PAU) and intramural aortic hematoma (IMH). Their diagnosis and treatment are similar to standard treatment.
Aortic Occlusion
The aorta can become blocked off to the point that no blood can get from the aorta to the legs and pelvis. This can happen slowly over time or can happen all at once, in some cases because of atherosclerotic disease. The treatment is different depending on the cause but when it happens abruptly it is almost always a surgical emergency.
