Is your chest a balloon-like bulge? (Thoracic Aortic Aneurysm) - Let's talk about this!

Do you sometimes feel pain in your chest, neck, or jaw? Or a little difficulty breathing, or a feeling of choking when swallowing? Most of the time, we forget about these things, thinking that they are normal, maybe something like gastritis. However, sometimes these can be a sign of something that needs a little attention. So, today we are going to talk about a balloon-like swelling that can occur in the main blood vessel in our chest, the aorta . In medicine, we call this a `Thoracic Aortic Aneurysm` .

What is this `Thoracic Aortic Aneurysm`? Simply put...

Imagine that your house has a main water supply system. That's how the aorta in our body works. This is the largest and most important artery that carries blood from the heart to the entire body. It's shaped like a tube.

Now, this `Thoracic Aortic Aneurysm` is when the wall of your aorta that runs through your chest (that's why it's called `Thorax` or chest cavity) becomes weak and bulges out like a balloon in one place. Some people also call this a dilation or widening of the artery. Generally, if that part of the aorta is wider than 50% of its normal width, we consider it an `Aneurysm`, or a bulge/bulge. This ``normal width`` can vary from place to place in the aorta.

These bulges can occur anywhere in the aorta. Most often, they occur in the abdomen (we call them `Abdominal Aortic Aneurysm`), but about one in four people can develop this condition in the chest.

Small aneurysms may not require major treatment. Medications and regular imaging tests (such as scans) to control the underlying condition may be enough. However, if your aneurysm is large or growing rapidly, surgery may be necessary to prevent life-threatening complications . Doctors will decide on the best treatment for you and when to perform it, because they want you to get the best results.

How common is this condition?

This condition, called `Thoracic Aortic Aneurysm`, usually affects between 6 and 10 per 100,000 people. However, it is difficult to say the exact number, because most of the time these aneurysms do not show any symptoms and therefore go undetected. About 20% of the patients currently diagnosed have a family history of the condition, meaning there is a genetic link.

In the United States alone, it is estimated that about 30,000 people die each year from aortic dissection or rupture, so this is not something to be taken lightly.

What are the symptoms of a Thoracic Aortic Aneurysm?

Most people with an aneurysm don't know they have it, because it often doesn't cause symptoms . However, sometimes it can show signs like these:

• Feeling pain in your jaw, neck, chest, or upper back .
• Difficulty swallowing or pain when swallowing (if the aneurysm is pressing on your esophagus).
• Hoarseness of voice (if this aneurysm is compressing the nerves that control your voice).
• Coughing or difficulty breathing (if the aneurysm is compressing your airway).

Symptoms of an aneurysm rupture (`Rupture`) or dissection (`Dissection`) - these are an emergency!

Many people have no symptoms, and then suddenly an aneurysm can rupture or disintegrate. Both of these are medical emergencies that require immediate treatment! Symptoms can start suddenly and can be very severe. If you or someone else has any of these symptoms , you should go to the hospital immediately :

• Sudden, unbearable pain in the chest or back. Some people describe it as stabbing, tearing, or exploding.
• Dizziness or a feeling of spinning.
• Difficulty breathing.
• Heart rate increases.
• Excessive sweating.
• Confusion.
• Difficulty speaking.
• Loss of vision.
• Weakness or numbness on one side of the body.

In a situation like this , every hour and minute counts. The longer you delay seeking treatment, the less likely you are to save your life. So don't take these symptoms lightly.

What are the causes of `Thoracic Aortic Aneurysm`?

The main cause of a Thoracic Aortic Aneurysm is a condition called Atherosclerosis. Simply put, this is when fatty deposits (plaque) build up inside the walls of our blood vessels, gradually narrowing them. Over time, these fatty deposits weaken the walls of the aorta, making it more likely to develop an aneurysm.

Normally, the walls of our aorta are strong and should be able to expand and contract as needed when blood flows. Think about it, this aorta is where blood comes directly from the heart. So, it should be able to withstand the pressure created when the heart pumps blood hard.

A healthy aorta can do this without any problems. However, if the walls of the aorta are weakened, the pressure from the heart can cause a section of the aorta to bulge outward, forming an aneurysm. This bulge is abnormal, changing the shape of the aorta's tube. As blood continues to flow through this bulge, more pressure is put on the already weakened walls, weakening them even more. As a result, the walls bulge even more. The larger an aneurysm gets, the more dangerous it becomes.

What are the risk factors?

Anything that weakens the walls of the aorta increases the risk of developing an aneurysm. In addition to atherosclerosis, there are several other risk factors:

• Aortitis : An inflammation of the aorta.
• `Bicuspid aortic valve disease` : The aortic valve of the heart has two leaflets (normally there should be three).
• Coronary artery disease (CAD) : Diseases related to the coronary arteries that supply blood to the heart muscle.
• Having a family history of aneurysm (family history).
• High blood pressure .
• Loeys-Dietz syndrome : A rare genetic condition involving connective tissue.
• Marfan syndrome : Another genetic condition that affects connective tissue.
• Being over 65 years of age.
• Smoking or using any tobacco product.
• `Turner syndrome` : A genetic condition that only affects females.
• Vascular Ehlers-Danlos syndrome : A rare connective tissue disease that affects the blood vessels.

Can Thoracic Aortic Aneurysm be inherited?

Yes, Thoracic Aortic Aneurysm can run in families. That means it can be passed down through generations. Researchers have identified several genetic mutations that increase the risk. Of these, mutations in the ACTA2 gene are the most common.

The ACTA2 gene tells our body to make certain proteins in the walls of our arteries. These proteins help the walls of our arteries maintain their shape by supporting the pressure of blood flowing through them. If there is a mutation in the ACTA2 gene, the walls of our arteries can stretch too much when blood flows through them.

However, you cannot say that you have inherited a genetic mutation just because you have an aneurysm. However, the risk is higher. If someone in your immediate family (biologically related) has had a Thoracic Aortic Aneurysm, it is a good idea to talk to your doctor. He or she may also recommend genetic testing .

Where does this `Thoracic Aortic Aneurysm` occur?

These form where the walls of the aorta are weakened. Things like `Atherosclerosis` (fatty deposits) that we talked about earlier, or connective tissue diseases, weaken the walls of the aorta, making it easier for `Aneurysm` to form.

Did you know that the aorta is the largest blood vessel in our body? It's like an old-fashioned walking stick. It starts at the heart, curves up, and then goes down through the chest and abdomen. It ends just above the navel.

Most often, a Thoracic Aortic Aneurysm develops in the ascending aorta or descending aorta. Rarely, it can also develop in the arched part of the aorta – the part that looks like the handle of a stick.

How serious is a `Thoracic Aortic Aneurysm`?

Thoracic Aortic Aneurysm is a serious medical condition. There are several complications that can occur:

• Aneurysm rupture .
• Aortic dissection .
• Blood clots form at the site of the aneurysm and travel to other parts of the body (thromboembolism). These blood clots can cause serious conditions such as stroke or mesenteric ischemia .
• Aortic valve regurgitation .

These are really serious conditions. That's why we need to be careful about this `Aneurysm`.

How is this `Thoracic Aortic Aneurysm` diagnosed?

Most often, a Thoracic Aortic Aneurysm is discovered by accident . This means that it is discovered when doctors are doing tests for another reason. For example, a chest X-ray may show that the middle part of your chest (the mediastinum) is wider than normal. This could be a sign of an aneurysm.

If your doctor suspects a Thoracic Aortic Aneurysm, either through an X-ray or for other reasons, he or she will order the following tests:

• `Computed tomography (CT) angiogram` : This is a specialized CT scan.
• `Echocardiogram (echo)` : An ultrasound scan of the heart.
• Magnetic resonance angiogram (MRA) : A scan that looks at blood vessels using MRI technology.
• Abdominal ultrasound : An ultrasound test to check for an aneurysm in the abdominal aorta.

What are the treatments for Thoracic Aortic Aneurysm?

Aorta surgery is the main and most permanent treatment for Thoracic Aortic Aneurysm. Doctors use a variety of surgical techniques. Some of them include:

• Traditional open surgery : This involves making a long incision down the middle of the chest, removing the damaged part of the aorta, and replacing it with an artificial tube (graft). This method is used to treat aneurysms in the ascending aorta, as well as complex aneurysms in the chest and abdomen.
• Thoracic endovascular aortic repair (TEVAR) : This is a minimally invasive surgical procedure. This means it is done without making large incisions. It is used to treat aneurysms in the descending aorta. In this procedure, the surgeon makes small incisions in your groin, uses an artery (femoral artery) that passes through it, and uses a catheter (thin tube) to insert a graft into the aneurysm.
• Aortic root replacement : This surgery is done for an aneurysm in the aortic root, where the aorta meets the heart. This may involve replacing your aortic valve as well. Alternatively, valve-sparing techniques can be used to keep your natural valve intact.

Sometimes, surgeons combine more than one of these methods (for example, open surgery and endovascular treatment) depending on the nature of the aneurysm. Receiving treatment at an aorta center increases your options and your chances of a good outcome.

When will I need surgery?

The doctor will decide whether you need surgery, and if so, when, by considering these factors:

• The size and location of the aneurysm.
• How fast the aneurysm grows .
• Whether the aneurysm causes symptoms and how severe they are .
• Other underlying medical conditions you have.

If the aneurysm is large or causing symptoms, surgery may be needed to prevent it from bursting. The size of an aneurysm is important because the larger it is, the more likely it is to burst. Typically, doctors will decide to perform surgery if the aneurysm is between 2 and 2.2 inches (about 5 to 5.5 centimeters) wide, or if it is growing at a rate of about half a centimeter per year.

But, it's not just the size that counts. If you have a connective tissue disorder, a bicuspid aortic valve, or other factors that increase your risk of rupture or rupture, your doctor may decide to perform surgery sooner. Talk to your doctor about the size of your aneurysm and when surgery might be needed.

"Watchful waiting"

If the aneurysm is small and has no symptoms, you may not need surgery right away. Instead, your doctor will monitor your condition (this is called watchful waiting). They may also prescribe medications to reduce the risk of complications.

For example, imaging scans may be ordered every 6 to 12 months to check for changes in the aneurysm. You may also be given medication to lower your blood pressure and reduce the pressure on the weakened part of your aorta. Your doctor may recommend surgery when the benefits of surgery outweigh the risks .

Can a Thoracic Aortic Aneurysm be prevented?

There is no specific way to prevent this condition. However, you can reduce your risk of developing atherosclerosis (a major cause of aneurysms). Here are some things you can do:

• Control your blood pressure and cholesterol levels.
• Follow a heart-healthy diet (e.g., the Mediterranean Diet ).
• Avoid all tobacco products.
• Get at least 150 minutes of moderate-intensity exercise per week (but talk to your doctor before starting a new exercise plan).
• Have an annual medical check-up, and attend all scheduled follow-up appointments.

How long can you live with a Thoracic Aortic Aneurysm?

Survival time depends on many factors, including the size of the aneurysm and whether it causes complications. Large aneurysms can be dangerous. About 65% of people with a large, untreated aneurysm survive one year after diagnosis. Only 20% survive five years.

However, with proper treatment, your life expectancy can be greatly increased and you can live a long, healthy life. That's why it's important to know if you're at risk for developing a Thoracic Aortic Aneurysm and work with your doctor to manage the condition.

How do I take care of myself?

If you have an aneurysm, your doctor will give you advice on how to take care of yourself. He or she may say things like:

• Avoid strenuous exercise. Things like heavy weightlifting or high-intensity interval training (HIIT) can put extra strain on your arteries. Ask your doctor what types of exercise are safe for you.
• Avoid tobacco use. Tobacco increases the risk of many cardiovascular diseases. If you smoke or use other tobacco products, seek help to quit.
• Make changes to your diet. You may need to reduce your salt intake or make other changes that are good for your artery health.
• Take your medications as prescribed. You may need medications to control underlying medical conditions. Ask your doctor if you have questions about how to take these medications.
• Avoid substances that increase heart rate. Examples include cocaine, amphetamines, and some herbal supplements.

When should I see my doctor?

See your doctor for an annual checkup, and keep all your follow-up appointments. Call your doctor right away if:

• If you notice new symptoms or changes in existing symptoms .
• If the medication causes unexpected side effects .
• If you have questions or concerns about your treatment plan.

When should I go to the emergency room (ER)?

If you have symptoms of an aneurysm bursting or rupturing, call 911 (1990 in Sri Lanka) or go to the nearest emergency room immediately. These are medical emergencies that require immediate treatment to save your life.

What questions should I ask my doctor?

If your doctor tells you that you have a Thoracic Aortic Aneurysm, you may not know what to ask first. Here are some questions to get you started:

• How big is my aneurysm?
• Is this amount something to be concerned about?
• What could have caused this `aneurysm`?
• What kind of treatment do you recommend for me?
• What changes do I need to make in my lifestyle?
• How often should I come for follow-up tests?

What is this `Thoracoabdominal aneurysm`?

This is also a type of `Aneurysm`. This is an `Aneurysm` that extends through both your chest (`Thorax`) and your stomach (`Abdomen`). This type accounts for about 15% of all `Aneurysms` that develop in the aorta.

Finding out you have an aneurysm in your chest can be scary. Maybe you've never thought about the health of your arteries or how they work. Or, maybe you were born with a connective tissue disease, so you're very aware of the inner workings of your body. No matter what you know, now is the time to learn more about your condition and take action to reduce your risk of complications.

Talk to your doctor about what you can expect based on your condition. He or she will be able to tailor a treatment plan to your needs, answer your questions, and provide you with the knowledge you need to move forward.

Finally, things to remember (Take-Home Message)

Thoracic Aortic Aneurysm is a serious condition. However, with early awareness, proper medical advice, and appropriate treatment, you have a great chance of living a healthy, long life.

• Pay attention to symptoms: Don't ignore things like sudden, severe chest or back pain.
• Get tested if you have risk factors: If someone in your family has had this condition, or if you have high blood pressure or smoking, seek medical advice.
• Follow your doctor's instructions exactly: take your prescribed medications, follow the instructions on exercise and diet, and attend scheduled tests and appointments.
• Avoid smoking completely: This is one of the most important things you can do.

Don't worry, you're not alone. Your medical team is ready to help you. The most important thing is to be aware of this condition and actively take care of your health.
