An aortic dissection is a life-threatening medical emergency caused by a tear in the inner layer of the aorta, the main artery carrying oxygen-rich blood from the heart to the body. This tear allows blood to flow between the layers of the aortic wall, causing the tear to expand. It often begins suddenly, with severe chest or upper back pain, shortness of breath[8], low blood pressure, confusion, and even stroke-like symptoms. Risk factors include high blood pressure, aortic aneurysms, genetic disorders like Marfan Syndrome, drug use, and pregnancy-related complications. Aortic dissections are classified as Type A (closer to the heart and more dangerous) or Type B (further down the aorta). Diagnosis requires rapid imaging like CT scans and echocardiograms. Type A usually needs emergency surgery, while Type B may be managed with medications or surgery based on severity. Early detection, swift treatment, and blood pressure control are key to survival and prevention.
An Aortic Dissection is an injury to the innermost layer of the aorta, the largest artery in the body. The aorta transports oxygen-rich blood from the left ventricle of the heart to the rest of the body, a critical function. Imagine your circulation system is a tree; The ground is your heart, and water is your blood. The tree needs to move water up, through its trunk, up into all its individual branches, and then transport the water into all of its leaves. The aorta is the trunk. If the trunk is chopped, then water cannot reach into any of the branches, and consequently the leaves – The entire tree dies. When the aorta tears, blood rushes through the opening, forcing the tear to open further.
Aortic dissections are rare but have a very high mortality rate. If the patient doesn’t receive quick medical attention, correct diagnosis and proper treatment within the first few hours, they are in danger. 1 in 5 patients don’t survive the first 24 hours without treatment. It is very important for us to understand the symptoms and act quickly if we see them, for the sake of ourselves and those around us. Early diagnosis and treatment improve the chances of survival by a large margin.
Aortic dissection has symptoms similar to other serious heart problems, like heart attacks. Usually, they begin very abruptly, and usually occur after a heavy exertion, like lifting something heavy or running up the stairs too fast. The sudden intensive activity increases blood pressure and presumably initiates the tear. However, sometimes they can occur in your sleep or while resting too. There is usually no clear warning before an aortic dissection.
Patients who have developed a tear in the aorta usually experience sudden, severe, stabbing pains in the chest or upper back. The pain could also spread to the neck or stomach. They will also be short of breath and have low blood pressure. This could cause dizziness or make them faint. Patients usually also experience confusion, loss of vision, rapid pulse and sweat. Sometimes patients also experience stroke-like symptoms, including weakness on one side, paralysis and slurred speech. If anyone you know is experiencing these symptoms, it is crucial to call an ambulance for immediate medical help.
Patients with pre-existing medical conditions like hypertension[9], hardened arteries due to plaque deposits (atherosclerosis), aortic aneurysms and aortic valve defects. Some genetic conditions can also increase your risk of aortic dissection – Turner Syndrome, Marfan Syndrome, Ehlers-Danlos Syndrome and Loeys-Dietz Syndrome. Drug abuse, especially drugs that temporarily raise blood pressure like cocaine or amphetamines, also increases your risk of aortic dissection. Being pregnant with high blood pressure could also put you at risk of aortic dissections.
An aortic dissection is a very serious medical event and can cause severe complications. This includes severe internal bleeding, that could result in death. Patients may also suffer organ damage, due to lack of blood supply. Other potential complications include stroke and cardiac tamponade (blood pooling into the pericardium, around the heart).
When a patient arrives at the emergency medical wing with chest pain, the doctors act quickly to diagnose them. They may suspect that the patient’s aorta is ruptured based on their symptoms, but they need to confirm it and eliminate other conditions like stroke or heart attack in order to provide the correct treatment. The diagnosis process needs to happen very quickly, because every extra minute puts the patient at risk.
The doctors will typically order a panel of tests, including a chest X-ray, a CT scan, a Transthoracic Echocardiogram, a Transoesophgeal Echocardiogram, and an MRI scan. The chest X-ray is a quick, low-radiation scan to ascertain the zone in which the problem has occurred. This zone will be investigated in more detail when the rest of the scans are performed.
Aortic dissections are classified according to the Stanford and DeBakey system, which classifies them into 2 major types:
Type A – This includes all tears in the upper part of the aorta, called the ascending aorta. Type A tears are closer to the heart and are typically more dangerous. They require emergency surgical repair to save the patient.
Type B – This includes all tears in the descending aorta. These tears are further away from the heart. Type B tears must be assessed, to evaluate how critical the case is. If blood flow to vital organs is cut off, the patient may require emergency surgery. However, in mild cases, the patient may be started on blood pressure medication and evaluated further before surgery.
An aortic dissection is a medical emergency and requires immediate comprehensive care. The treatment may include a combination of surgical interventions and medication, depending on which part of the aorta is ruptured.
Treatment for Type A Aortic Dissection – Type A aortic dissections require immediate treatment. The internal bleeding from the aortic tear needs to be stopped as quickly as possible. Emergency surgical intervention is usually required. The surgeon will choose to use open-heart surgery techniques or endovascular techniques, based on the state of the patient and the location of the tear. A hybrid approach may also be taken, if the surgeon deems it most appropriate for that patient. For acute Type A aortic dissections, the damaged portion of the aorta is usually removed and replaced with a synthetic tube called a graft, in an open procedure. The aortic valve may also require repair. Patients with Type A dissections will also be given medication to reduce the heart rate and lower blood pressure before the surgery. After surgery, the patient may need medication and permanent lifestyle changes to manage their condition. Regular check-ups for monitoring the heart may also be required.
Treatment for Type B Aortic Dissection – Type B aortic dissections are treated based on severity and location. If the dissection cuts off blood flow to a vital organ, it will need to be repaired to restore blood flow immediately. If left untreated for too long, the vital organ could fail. Often, patients with Type B aortic dissections are given beta-blockers and strong pain medication to lower their heart rate and blood pressure. They may require surgical interventions later, if complications develop. Acute Type B dissections can be treated with endovascular techniques. The surgeon can repair the tear using a stent graft. This is a synthetic tube with a metal support structure. The repair can be done using catheters, through an incision in the femoral artery.
Many of the risk factors that make you susceptible to an aortic dissection are outside of your control. However, making good lifestyle choices is definitely beneficial. Managing your blood pressure and cholesterol levels can reduce your risk of aortic dissection. Maintaining a healthy weight and exercising regularly contributes to good overall heart health. Avoid tobacco products, cocaine and amphetamines at all costs.
How do I know if chest pain is an aortic dissection or a heart attack?
Aortic dissection pain is usually sudden, severe, and described as “tearing” or “ripping,” often spreading to the back. Unlike a heart attack, it may also cause fainting, confusion, or stroke-like symptoms. Immediate emergency care is critical.
Is aortic dissection always fatal?
Not always, but it is extremely dangerous. Survival depends on how quickly treatment is given. Early diagnosis and emergency care significantly improve outcomes.
What should I do if someone shows symptoms of aortic dissection?
Call an ambulance immediately. Do not wait or try home remedies. Quick hospital intervention with imaging and specialist care can be lifesaving.
Who is at high risk for aortic dissection?
People with high blood pressure, aortic aneurysm, genetic conditions like Marfan Syndrome, or a history of heart disease are at higher risk. Smoking and drug use can also increase risk.
Can aortic dissection happen without warning?
Yes. Many patients have no prior symptoms. It can occur suddenly, even during rest or sleep, which is why awareness of warning signs is important.
How is aortic dissection diagnosed quickly?
Doctors use emergency imaging like CT scans, echocardiography, or MRI to confirm the condition. Rapid diagnosis helps decide between surgery or medical management.
Can aortic dissection be prevented?
While not all cases are preventable, controlling blood pressure, avoiding smoking, and regular heart check-ups can significantly reduce risk.
