An abdominal aortic aneurysm (AAA) is a bulge in the aorta, the artery that carries blood from the heart to the abdomen. This bulging is caused by a weakness in the aortic wall, which can lead to a rupture and potentially life-threatening bleeding. While many people with AAA do not experience symptoms, some may have deep pain in their lower backs, belly, or a pulsing sensation in their bellies. If you experience symptoms like low blood pressure, difficulty breathing, an increased heart rate, or sudden, intense pain in the abdomen, you should seek immediate medical attention.

Abdominal aortic aneurysm symptoms
An abdominal aortic aneurysm (AAA) is a bulge in the part of the aorta that runs through the abdomen. The aorta is the largest blood vessel in the body, delivering oxygenated blood from the heart to the rest of the body. An abdominal aortic aneurysm forms in an area where the wall of the aorta is weak.
Most people with abdominal aortic aneurysms do not exhibit any symptoms. However, symptoms may manifest if the aneurysm grows in size and starts putting pressure on the surrounding organs. The most common symptom is general belly pain or discomfort, which may be constant or come and go. The pain may be dull or severe, deep, aching, gnawing, or throbbing, and it may last for hours or days. It is generally not affected by movement, although certain positions may be more comfortable. The pain may spread to the groin, buttocks, or legs.
Other symptoms of an abdominal aortic aneurysm include a pulsing feeling in the belly, similar to a heartbeat, and pain in the chest, lower back, or flank (over the kidneys).
If an abdominal aortic aneurysm ruptures, it can cause sudden, severe pain in the abdomen or back, an extreme drop in blood pressure, and signs of shock. Without immediate treatment, it can quickly lead to death. Other symptoms of a ruptured aneurysm include a fast heartbeat, dizziness or fainting, nausea or vomiting, and clammy, sweaty skin.

AAA risk factors
Abdominal aortic aneurysm (AAA) is a bulge in the part of the aorta that runs through the abdomen. Most people with AAA do not experience symptoms until the aneurysm is close to rupturing. However, some common symptoms include deep pain in the lower back or belly, a pulsing sensation in the belly, and clammy, sweaty skin. If the aneurysm bursts, it can cause sudden, severe pain.
Several risk factors are associated with AAA. Older age is a significant factor, with AAA typically occurring after 55 years of age. Men are more likely to develop AAA than women. Smoking is one of the primary risk factors, and the risk increases with the number of cigarettes smoked daily and the number of years of smoking. Other stimulant use, such as cocaine, also increases the risk by elevating blood pressure.
Certain medical conditions can also contribute to the risk of AAA. These include cardiovascular conditions such as atherosclerosis, coronary heart disease, and peripheral artery disease. High blood pressure, or hypertension, is a leading risk factor for AAA. Bacterial infections and arteritis have also been implicated in the development of AAA. Additionally, genetic factors play a role, with Marfan syndrome and Ehlers-Danlos syndrome strongly associated with AAA.
Individuals with aneurysms in other blood vessels or a family history of AAA may be at increased risk. Trauma to the abdomen and inflammation or infection in the aorta can also contribute to the development of AAA. Monitoring biomarkers such as white blood cell count, fibrinogen, and C-reactive protein can help with early AAA risk assessment, as they indicate the presence of inflammation and oxidative stress, which can impair the normal function of the vascular wall.

AAA diagnosis
An abdominal aortic aneurysm (AAA) is a bulge in the part of the aorta that runs through the abdomen. It is caused by an underlying weakness in the wall of the aorta, which can be the result of atherosclerosis or plaque buildup. As the aneurysm grows, the abdominal aorta balloons outwards, increasing the risk of rupture.
Most people with AAA do not exhibit any symptoms, but as the aneurysm grows, it may put pressure on surrounding organs, leading to symptoms such as:
- Deep pain in the lower back or belly, which may be constant or come and go.
- A pulsing sensation in the abdomen.
- "Cold foot" or a black or blue painful toe, indicating a blood clot.
- Fever or weight loss, if the aneurysm is caused by infection or inflammation.
- Shortness of breath.
- Fast heartbeat.
- Low blood pressure.
- Dizziness or fainting.
- Nausea or vomiting.
- Clammy, sweaty skin.
If you are experiencing any of these symptoms, it is important to seek immediate medical attention.
To diagnose AAA, a healthcare provider will typically perform a physical examination and an imaging test. During the physical exam, the provider may feel your stomach area, listen to your heart for any abnormalities, check your pulse in your arms and legs, and look for symptoms of medical conditions that are risk factors for AAA, such as Marfan or Ehlers-Danlos syndromes.
Imaging tests used to diagnose AAA include:
- Ultrasound: This is a highly accurate method to measure the size of the aneurysm and monitor its progression over time.
- Computed Tomography (CT) scan: Provides detailed information about the shape and location of the aneurysm.
- Magnetic Resonance Imaging (MRI): Offers insights into the size, shape, and location of the aneurysm.
- Echocardiography: Provides information about the size of the aneurysm and the thoracic aorta.

AAA treatment
An abdominal aortic aneurysm (AAA) is a bulge in the part of the aorta that runs through the abdomen. It is a potentially life-threatening condition that requires immediate medical attention. The aorta is the largest blood vessel in the body, delivering oxygenated blood from the heart to the rest of the body. An aneurysm occurs when there is a weakness in the wall of the aorta, causing it to balloon out and potentially rupture. Older age, tobacco use, and high blood pressure are some of the risk factors associated with AAA.
Most individuals with AAA do not exhibit any symptoms, but as the aneurysm grows, it can put pressure on surrounding organs, leading to symptoms such as belly pain or discomfort, lower back pain, leg pain, shortness of breath, fast heartbeat, dizziness, nausea, and clammy skin. If the aneurysm ruptures, it can cause sudden and severe pain and be life-threatening.
The treatment options for AAA aim to prevent rupture and control the growth of the aneurysm. Small, slow-growing aneurysms may be managed with lifestyle changes, medication, and careful monitoring. Larger or faster-growing aneurysms may require surgical intervention to repair or remove the aneurysm and prevent rupture. Endovascular aneurysm repair (EVAR) is a common surgical procedure where a small incision is made in the groin, and a stent graft (a metal mesh tube covered in fabric) is inserted into the femoral artery and guided to the aneurysm site using X-ray. This method supports the weakened blood vessel and reduces the risk of rupture.
In some cases, open surgery may be necessary, especially if the aneurysm involves the arteries of the kidneys. During this procedure, a traditional stent graft is inserted, but it does not have openings to accommodate the branching of the aorta to the kidneys. Additionally, clinical trials and research are continuously being conducted to evaluate new medical approaches, devices, drugs, or other treatments for AAA.

Aorta function
The aorta is the body's largest artery, over a foot long and an inch wide at its widest point. It carries oxygen-rich blood from the heart to the rest of the body. The aorta is essential to human well-being, providing a steady supply of oxygen and nutrients to organs, muscles, nerves, and supporting tissue.
The aorta has three layers of tissue. The inner layer, or tunica intima, is a tube through which blood passes. It contains smooth muscle tissue, connective tissue, and endothelial cells, which enable blood to transport oxygen and nutrients without absorption until they reach the right spot. The middle layer, or tunica media, is made of smooth muscle tissue, elastin, and collagen (proteins). These substances enable the aorta to adapt to the body's changing blood flow needs.
The aorta has several sections, each with its own characteristics and potential health risks. The aortic root is the transition point where blood exits the heart. It contains the aortic valve, the origins of both coronary arteries, and an elastic segment called the sinuses of Valsalva. The ascending aorta is the portion between the aortic root and the aortic arch. At the junction where the aortic root and ascending aorta meet, the aorta becomes less elastic and more rigid. The aortic arch is where the aorta transitions from the center of the chest to the back. Blood vessels from the aortic arch supply blood to the arms and legs. The descending aorta runs through the chest and abdomen, starting after the aortic arch. The abdominal aorta is the largest artery in the abdomen and runs from the descending aorta down to just below the navel.
Diseases of the aorta can have serious health consequences. An aortic aneurysm is a bulge in the aorta that occurs when there is a weakening in the wall of the aorta. Aneurysms can be caused by infection, smoking, high blood pressure, atherosclerosis, trauma, or genetic conditions. Abdominal aortic aneurysms can cause back or belly pain or a pulsing sensation in the belly. If an aortic aneurysm ruptures, it can cause sudden, severe pain, low blood pressure, dizziness, nausea, clammy skin, and other symptoms. Aneurysms and dissections of the aorta are life-threatening medical emergencies that require surgery and/or medication.
