Aortic Dissection: Symptoms, Causes, Complications, Treatment, and Prevention

Have you ever heard of a medical condition that can become life-threatening within just minutes? Aortic dissection is one of the cardiovascular emergencies that often goes undetected until it is too late. Although it is rarely discussed, this condition needs treatment as quickly as possible because every second counts in saving a life.

Aortic dissection may sound rare, but its impact is very serious. According to data from the American Heart Association (AHA), aortic dissection is estimated to occur in 3 to 4 cases per 100,000 people each year worldwide. In Indonesia, although specific data are still limited, reports from several heart hospitals show that cases are increasing, especially in people aged 50 to 70.

Risk factors such as uncontrolled hypertension, a smoking habit, and a family history of cardiovascular disease also contribute to the rise in cases. Globally, aortic dissection accounts for about 2% of all deaths from cardiovascular disease. This figure underlines the importance of being aware of the symptoms, risk factors, and early treatment to prevent fatal consequences.

By understanding aortic dissection more deeply, we can take preventive steps and recognize its signs before it is too late. In this article, we discuss in depth what aortic dissection is, its symptoms, causes and risk factors, the diagnostic process, treatment options, and prevention steps, so you can protect yourself and your family from the risk of this disease.

01 / Blood Vessel Disease

What Is Aortic Dissection?

Aortic dissection is an emergency in which the inner layer of the aorta, the largest and most important blood vessel that carries blood from the heart to the rest of the body, tears. This tear causes blood to flow between the layers of the aortic wall, weakening the vessel and putting it at risk of rupture. Without prompt treatment, this condition can be fatal.

Differences Between Aortic Dissection and Other Aortic Conditions

Aortic dissection is often mistaken for a heart attack or stroke because the symptoms are similar, such as sudden and severe chest pain. However, there are fundamental differences between the three:

• Heart Attack: Occurs when blood flow to the heart muscle is blocked, usually because of a blockage in a coronary artery.
• Stroke: Occurs when blood flow to the brain is disrupted, either by a blockage (ischemic stroke) or by a ruptured blood vessel (hemorrhagic stroke).
• Aortic Dissection: Occurs in the aorta, not in the heart or brain, and involves a tear in the wall of the blood vessel.

These differences matter because the treatment for each condition is very different. For example, a heart attack may require blood thinners, whereas aortic dissection often requires emergency surgery.

Types of Aortic Dissection

Aortic dissection can be divided into several types based on where the tear is located in the aorta. This classification is important because it determines the treatment method and how urgent the care is. Here are the types of aortic dissection you should know:

1. Type A Aortic Dissection

Type A aortic dissection occurs when the tear is in the part of the aorta that rises from the heart (ascending aorta), the part closest to the heart. This type is the most dangerous and requires emergency surgery.

A characteristic feature of type A aortic dissection is that the tear can affect the aortic valve and cause blood to leak into the pericardium (the sac surrounding the heart), potentially leading to cardiac tamponade (a buildup of fluid around the heart).

2. Type B Aortic Dissection

Type B aortic dissection occurs when the tear is in the part of the aorta that runs downward (descending aorta), away from the heart. This type can often be treated without surgery, unless complications occur.

A characteristic feature of type B aortic dissection is that the tear does not affect the ascending aorta, so the risk of complications such as cardiac tamponade is lower.

3. Acute vs. Chronic Aortic Dissection

Besides location, aortic dissection can also be categorized by when it occurs:

• Acute Dissection: Occurs within less than 14 days of the first symptoms. This condition requires immediate treatment because the risk of complications is high.
• Chronic Dissection: Occurs more than 14 days after the first symptoms. Although it is less urgent, patients still need regular monitoring to prevent long-term complications.

According to the American Heart Association (AHA), about 60 to 70% of aortic dissection cases are type A, while 30 to 40% are type B.

Why Is Aortic Dissection Dangerous and Why Does It Need Immediate Treatment?

Aortic dissection is a very dangerous condition because it can cause serious complications in a short time. Here are several reasons why immediate treatment is crucial:

• Risk of Aortic Rupture: If the tear in the aortic wall gets worse, the blood vessel can rupture, causing massive and potentially fatal internal bleeding.
• Disrupted Blood Flow: Blood flowing between the layers of the aorta can block blood flow to vital organs such as the brain, kidneys, or intestines, which can cause permanent organ damage.
• High Death Rate: According to the Journal of the American College of Cardiology, about 40% of patients with acute aortic dissection die within 24 hours if not treated promptly. Even with medical treatment, the death rate remains high, reaching 30% within the first 30 days.

Symptoms of Aortic Dissection

In this section, we will discuss the symptoms that may appear when someone has an aortic dissection. Understanding the early signs is very important so that we can recognize this condition sooner and seek the right help.

Common Symptoms

Aortic dissection is often marked by symptoms that appear suddenly and are very severe. Here are common symptoms to watch out for:

• Sharp, Sudden Chest or Back Pain: This pain is often described as a tearing or ripping sensation and can spread to the neck, jaw, or lower back.
• Shortness of Breath: Difficulty breathing can occur because pressure on the aorta affects how the heart or lungs work.
• Cold Sweats and Dizziness: These symptoms often appear as the body’s response to severe pain or reduced blood flow to the brain.
• Weak or Irregular Pulse: Aortic dissection can affect blood flow, causing the pulse in one arm or leg to feel weak or absent.

These symptoms can appear suddenly and worsen quickly, so they require immediate medical attention.

Symptoms That Are Often Mistaken for Other Health Problems

Because its symptoms resemble those of other medical conditions, aortic dissection is often misinterpreted. Here are several conditions with symptoms similar to aortic dissection:

• Heart Attack: Severe chest pain is often thought to be a heart attack. However, in a heart attack, the pain usually feels like pressure or heaviness in the chest, not a tearing sensation.
• Stroke: If aortic dissection affects blood flow to the brain, symptoms such as weakness on one side of the body or difficulty speaking can be mistaken for a stroke.
• Digestive Problems: Pain that spreads to the abdomen or lower back is sometimes thought to be a digestive problem, such as gastritis or kidney stones.

It is important to recognize these differences because the treatment for each condition is very different. For example, blood thinners used for a heart attack can actually be dangerous for patients with aortic dissection.

According to the American Heart Association (AHA), every minute that passes without treatment can increase the risk of death *. Therefore, do not delay seeking medical help if you suspect an aortic dissection. (* Source: American Heart Association, Predicting Death in Patients With Acute Type A Aortic Dissection)

Causes and Risk Factors of Aortic Dissection

Below are the causes that can trigger a tear in the aortic wall, the factors that increase the risk, and how everyday lifestyle can affect the health of your blood vessels.

Main Causes

Aortic dissection occurs when the inner layer of the aortic wall tears, allowing blood to flow between the layers of the vessel wall. The main causes of this tear are:

1. High Blood Pressure (Hypertension): Uncontrolled hypertension is the most common cause. High blood pressure puts excessive strain on the aortic wall, increasing the risk of a tear.
2. Congenital Conditions of the Aorta: Some people are born with abnormalities in the structure of the aorta, such as Marfan syndrome or Ehlers-Danlos syndrome, which make the aortic wall weaker and more prone to tearing.
3. Chest Injury: Physical trauma, such as a car accident or a sports injury, can damage the aortic wall and trigger a dissection.

Risk Factors That Increase the Likelihood of Aortic Dissection

In addition to the main causes, several risk factors can increase a person’s chance of developing aortic dissection:

• Age: The risk increases with age, especially in men aged 60 to 70.
• Sex: Men have a higher risk than women.
• Family History: If a family member has had aortic dissection or another aortic disease, your risk also increases.
• Heart and Blood Vessel Disease: Conditions such as atherosclerosis (plaque buildup in the blood vessels) or an aortic aneurysm can weaken the aortic wall.
• Drug Use: Cocaine or amphetamine abuse can cause a sudden rise in blood pressure, which can trigger a tear in the aorta.

Lifestyle Factors That Affect Risk

Everyday lifestyle also plays a major role in increasing or reducing the risk of aortic dissection. Here are some lifestyle factors to pay attention to:

• Smoking: Smoking damages blood vessels and raises blood pressure, increasing the risk of aortic dissection.
• Unhealthy Diet: Too much salt, high-fat foods, and too little fiber can lead to hypertension and atherosclerosis.
• Lack of Physical Activity: A sedentary lifestyle, or not moving enough, can increase the risk of obesity and high blood pressure.
• Excessive Stress: Chronic stress can raise blood pressure, which eventually puts strain on the aortic wall.

About 70% of aortic dissection cases are linked to uncontrolled hypertension. Therefore, managing risk factors through lifestyle changes and appropriate treatment can significantly reduce the chance of this condition occurring.

Diagnosing Aortic Dissection

Diagnosing aortic dissection requires fast and accurate medical tests to confirm the patient’s condition. Here are several diagnostic procedures commonly used:

1. CT Scan (Computed Tomography): A CT scan with contrast is one of the accurate methods for detecting aortic dissection. This procedure provides detailed images of the structure of the aorta and shows any tear or separation of the layers of the aortic wall.
2. MRI (Magnetic Resonance Imaging): MRI is used if a CT scan is not available or cannot be performed. MRI provides a clear picture of the aorta without using radiation.
3. Echocardiography: An echocardiogram uses sound waves to create images of the heart and aorta. Transesophageal echocardiography (TEE) is often used because it provides more detailed images than standard echocardiography.
4. Chest X-Ray: Although it is not specific for aortic dissection, a chest X-ray can show indirect signs, such as a widened aorta or fluid buildup around the heart.

Aortic dissection is an emergency that requires immediate treatment. Every minute that passes without proper diagnosis and treatment can increase the risk of death.

According to the European Society of Cardiology (ESC), about 70% of patients with acute aortic dissection die within 48 hours if not treated promptly *. A fast and accurate diagnosis allows the medical team to decide on the right treatment, such as emergency surgery or medical therapy, to prevent serious complications such as aortic rupture or damage to vital organs. (* Source: European Society of Cardiology, Acute Aortic Dissection)

The Role of Specialists in Making the Diagnosis

Specialists, such as cardiologists or vascular surgeons, play a key role in diagnosing aortic dissection. They have the expertise to:

• Interpret Test Results: Specialists can read and analyze CT scan, MRI, or echocardiography results accurately to confirm the diagnosis.
• Decide on Treatment: Based on the diagnosis, the specialist will decide whether the patient needs emergency surgery, medication, or intensive monitoring.
• Monitor the Patient’s Condition: Once the diagnosis is made, the specialist will continue to monitor the patient to make sure the response to treatment is appropriate and to prevent further complications.

With this important role, specialists are at the forefront of saving the lives of patients with aortic dissection.

Treatment of Aortic Dissection

Treatment of aortic dissection depends heavily on its type and severity. In general, there are two main approaches: surgery and non-surgical management.

1. Surgery (Operation): Surgery is usually needed for type A aortic dissection, when the tear occurs in the part of the aorta close to the heart. The operation aims to replace the damaged part of the aorta with a graft (an artificial tube) and prevent the vessel from rupturing. This procedure is an emergency and must be done as quickly as possible to save the patient’s life.
2. Non-Surgical Management (Monitoring and Medication): For type B aortic dissection, when the tear occurs in the part of the aorta farther from the heart, non-surgical management is often the first choice. This approach involves:
   • Medications: Patients are given drugs to lower blood pressure and heart rate, such as beta-blockers or vasodilators, to reduce pressure on the aortic wall.
   • Intensive Monitoring: Patients are closely monitored in the intensive care unit (ICU) to make sure their condition is stable and not getting worse.
   • Endovascular Intervention: In some cases, a non-surgical procedure such as placing a stent graft (a tube-shaped graft) can be performed to repair the aorta without open surgery.

Comparing the Effectiveness of Treatment Options for Each Type of Dissection

The effectiveness of treatment varies greatly depending on the type of aortic dissection:

• Type A Aortic Dissection: Surgery is the main option to save the patient’s life. According to the Journal of Thoracic and Cardiovascular Surgery, the survival rate of patients who undergo emergency surgery for type A dissection is about 70 to 80% if it is performed within the first 24 hours. Without surgery, the death rate can reach 50% within 48 hours.
• Type B Aortic Dissection: Non-surgical management is often effective for patients with stable type B dissection. According to the European Heart Journal, about 80 to 90% of patients with type B dissection can survive with medical treatment and intensive monitoring. However, if complications such as aortic rupture or impaired blood flow to organs occur, surgical or endovascular intervention may be needed.

This comparison shows that the choice of treatment must be tailored to the type of dissection and the patient’s specific condition. Collaboration within a multidisciplinary medical team, including cardiologists, surgeons, and radiologists, is essential to determine the most suitable approach.

Prognosis and Recovery

The prognosis after treatment for aortic dissection varies depending on the type of dissection, how quickly it is treated, and the patient’s overall health. According to the Journal of the American College of Cardiology, patients who successfully undergo emergency surgery for type A aortic dissection have a survival rate of about 70 to 80% in the first year. However, the risk of long-term complications, such as an aortic aneurysm or heart failure, remains.

For type B aortic dissection treated without surgery, the prognosis is generally better, with a survival rate of 80 to 90% in the first year. However, patients need regular monitoring because the risk of complications such as extension of the tear or aneurysm formation remains.

Factors That Affect Recovery

Several important factors that affect a patient’s recovery after treatment for aortic dissection include:

• Age: Younger patients tend to recover better because their bodies are stronger and their risk of comorbidities is lower.
• General Health: Patients who were in good health before the dissection, such as having well-controlled blood pressure and no chronic disease, usually have a better prognosis.
• Adherence to Post-Operative Treatment: Following the doctor’s advice, such as taking medication regularly, attending routine follow-up visits, and living a healthy lifestyle, is very important to prevent complications and speed up recovery.

For recovery to go as well as possible, patients are advised to do the following:

1. Take Your Medication: Take prescribed medication, such as blood pressure medication, regularly and at the recommended dose.
2. Routine Follow-Up: Have regular checkups with your doctor to monitor the aorta and detect any new problems early.
3. Adopt a Healthy Lifestyle:
   • Eat foods low in salt and fat to keep blood pressure stable.
   • Avoid smoking and excessive alcohol consumption.
   • Do light physical activity, such as walking, after getting your doctor’s approval.
4. Manage Stress: Stress can raise blood pressure, so it is important to manage it with relaxation techniques such as meditation or yoga.
5. Watch for New Symptoms: Contact your doctor right away if you develop symptoms such as chest pain, shortness of breath, or unusual dizziness.

With proper treatment and discipline in post-operative care, patients can improve their quality of life and reduce the risk of long-term complications.

Preventing Aortic Dissection

Although aortic dissection is a serious condition, preventive steps can be taken to reduce the risk. Here are the steps you can take to prevent aortic dissection.

Managing Risk Factors

Managing risk factors is a key step in preventing aortic dissection. Here are several ways to do this:

• Control Blood Pressure: Hypertension is a major risk factor for aortic dissection. Keeping blood pressure in the normal range (below 120/80 mmHg) can significantly reduce the risk. Consult your doctor for the right medication or therapy if you have high blood pressure.
• Treatment of Genetic Conditions: If you have a genetic condition such as Marfan syndrome or Ehlers-Danlos syndrome, it is important to receive treatment and regular monitoring. Your doctor may recommend medications or special precautions to reduce the risk of damage to the aorta.

Lifestyle Changes to Reduce Risk

A healthy lifestyle can help maintain blood vessel health and reduce the risk of aortic dissection. Here are some changes you can make:

• Quit Smoking: Smoking damages blood vessels and raises blood pressure. Quitting smoking is an important step to protect the health of your heart and aorta.
• Balanced Diet: Eat foods that are low in salt, low in saturated fat, and rich in fiber, such as fruits, vegetables, whole grains, and healthy proteins. Avoid processed foods and foods high in sugar.
• Regular Physical Activity: Light exercise such as walking, cycling, or swimming for 30 minutes a day can help maintain healthy blood pressure and an ideal body weight.
• Manage Stress: Chronic stress can raise blood pressure. Try relaxation techniques such as meditation, yoga, or breathing exercises to manage stress well.

The Importance of Regular Checkups for High-Risk Individuals

Regular health checkups are very important, especially for people with high risk factors such as a family history of aortic disease, hypertension, or certain genetic conditions. Here are the benefits:

• Early Detection: Routine tests such as an aortic ultrasound or a CT scan can detect abnormalities of the aorta before they develop into a serious condition.
• Health Monitoring: Your doctor can check your blood pressure, cholesterol levels, and heart condition periodically to make sure everything is within normal limits.
• Faster Treatment: If a problem is found, treatment can be started as soon as possible to prevent further complications.

High-risk individuals should have an aortic checkup at least once a year. With early detection and proper treatment, the risk of aortic dissection can be minimized.

Complications of Aortic Dissection

Aortic dissection is a condition that can cause serious, even life-threatening, complications if not treated promptly. Here are several complications that may occur:

• Aortic Rupture: A tear in the aortic wall can cause the vessel to rupture, resulting in massive internal bleeding. This condition is often fatal if not treated immediately.
• Impaired Blood Flow to Vital Organs: Aortic dissection can block blood flow to important organs such as the brain, kidneys, or intestines. This can cause a stroke, kidney failure, or other organ damage.
• Aortic Aneurysm: The part of the aorta weakened by the dissection can form an aneurysm, a balloon-like bulge in the vessel wall. An aneurysm can rupture and cause serious bleeding.
• Heart Failure: If the dissection affects the aortic valve, it can cause the valve to leak (aortic regurgitation), which forces the heart to work harder. Over the long term, this can lead to heart failure.
• Cardiogenic Shock: In severe cases, aortic dissection can cause a drastic drop in blood pressure and impaired heart function, known as cardiogenic shock. This condition requires emergency medical treatment.

According to the Journal of the American Medical Association (JAMA), about 20 to 30% of patients with aortic dissection experience serious complications within 30 days of diagnosis. Therefore, immediate treatment and close monitoring are essential to prevent life-threatening complications.
