An aortic aneurysm is a condition that occurs when the wall of the aorta—the main blood vessel carrying blood from the heart to the rest of the body—develops a weak spot that bulges outward like a balloon. While it may sound frightening, it’s important to understand what an aortic aneurysm is, what can cause it, and how it can be managed to protect your health.
What Is an Aortic Aneurysm?
The aorta is the largest artery in your body, and it plays a crucial role in delivering oxygen-rich blood from your heart to the rest of your organs. When part of the aorta weakens, the pressure from the flowing blood can cause it to swell, forming what is known as an aneurysm.
There are two main types of aortic aneurysms:
1. Abdominal Aortic Aneurysm (AAA): This type occurs in the lower part of the aorta, in the abdomen.
2. Thoracic Aortic Aneurysm (TAA): This type occurs in the upper part of the aorta, in the chest.
Some aneurysms can grow slowly over time and become large without causing symptoms. However, they can be dangerous if they grow large enough to rupture, leading to life-threatening internal bleeding.
What Causes an Aortic Aneurysm?
The exact cause of an aortic aneurysm isn’t always clear, but certain factors can increase the likelihood of developing one:
• Atherosclerosis (Hardening of the Arteries): Plaque buildup in the arteries can weaken the walls of the aorta, contributing to aneurysm formation.
• High Blood Pressure: Constant high pressure can stress and damage the walls of the aorta, increasing the risk.
• Genetic Factors: Conditions like Marfan syndrome and Ehlers-Danlos syndrome can weaken the connective tissue of the aorta, making it more prone to aneurysms.
• Smoking: Smoking is a significant risk factor for aortic aneurysm, as it can damage the aorta and increase blood pressure.
• Age and Family History: The risk of an aortic aneurysm increases as you get older, and having a close family member with an aneurysm increases your risk.
Symptoms of Aortic Aneurysm
One of the challenges of detecting an aortic aneurysm is that they often don’t cause any symptoms until they become quite large or start leaking. However, depending on the type and size of the aneurysm, you may experience:
• Abdominal Aortic Aneurysm: A pulsating sensation near your belly button, deep, constant pain in your abdomen or back.
• Thoracic Aortic Aneurysm: Chest pain, back pain, coughing, or difficulty swallowing or breathing.
If an aneurysm ruptures, it can cause sudden and severe symptoms such as intense pain, dizziness, or loss of consciousness. A ruptured aortic aneurysm is a medical emergency that requires immediate care.
How Is an Aortic Aneurysm Diagnosed?
Because aortic aneurysms often don’t show symptoms until they are serious, they are sometimes discovered during routine tests or exams for unrelated health issues. The following imaging tests are commonly used to diagnose an aneurysm:
• Ultrasound: Often used for abdominal aneurysms; it’s a quick, non-invasive way to view the aorta.
• CT Scan (Computed Tomography): Provides a more detailed image of the aorta and is useful for determining the size of the aneurysm.
• MRI (Magnetic Resonance Imaging): Used to get clear images of the aorta and assess its condition.
Your doctor may also recommend screening if you are at high risk, such as being over 65 and having a history of smoking.
Treatment for Aortic Aneurysm
Treatment for an aortic aneurysm depends on the size, location, and rate of growth. Here are the primary treatment options:
1. Monitoring: If your aneurysm is small and not causing symptoms, your doctor may recommend regular check-ups to monitor its growth. This approach is known as “watchful waiting.”
2. Lifestyle Changes and Medications: Making lifestyle changes can help prevent the aneurysm from growing. This includes quitting smoking, managing high blood pressure with diet and exercise, and taking medications to control blood pressure or cholesterol.
3. Surgery: If the aneurysm is large, growing quickly, or causing symptoms, your doctor may recommend surgery to prevent rupture. There are two main types of surgery:
• Open Repair: Involves replacing the weakened section of the aorta with a synthetic tube (graft). This surgery requires a larger incision and a longer recovery time.
• Endovascular Repair (EVAR): This is a less invasive procedure where a stent graft is placed inside the aorta through a catheter, reinforcing the weak spot and reducing the risk of rupture.
How to Lower Your Risk
While some risk factors, such as age and genetics, cannot be controlled, there are steps you can take to reduce your risk of developing an aortic aneurysm:
• Quit Smoking: Smoking is a major risk factor for aneurysms, so quitting is one of the most impactful changes you can make.
• Control Blood Pressure: High blood pressure weakens artery walls, so keeping it in check can reduce your risk. This may involve diet, exercise, and medication.
• Exercise Regularly: Staying active helps maintain a healthy weight and supports heart health, which in turn benefits the aorta.
• Eat a Heart-Healthy Diet: A diet rich in fruits, vegetables, whole grains, and lean protein helps keep your arteries healthy and reduces the risk of atherosclerosis.
When to See a Doctor
If you are at risk for an aortic aneurysm, it’s essential to follow up with your doctor for regular screenings. Additionally, if you experience symptoms such as persistent pain in your abdomen, chest, or back, don’t ignore them. Early diagnosis and treatment can save lives.
Summary
An aortic aneurysm is a serious condition that can develop silently over time, but with regular monitoring and healthy lifestyle choices, the risks can be managed. Knowing the symptoms and your risk factors is crucial for preventing complications. If you have concerns about an aortic aneurysm or think you might be at risk, speak with your doctor for further guidance and evaluation.
