When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Aortic Dissection.
Aortic dissection occurs when the inner layer of the aortic wall develops a tear, allowing blood to surge through and separate the artery's layers.
Aortic dissection occurs when the inner layer of the aortic wall develops a tear, allowing blood to surge through and separate the artery's layers. The aorta has three layers - a smooth inner lining, a muscular middle layer, and a tough outer layer. When the inner layer weakens or tears, the incredible force of blood pumping from the heart creates a false passage between these layers, like water finding its way behind wallpaper.
Several factors can weaken the aortic wall and make it prone to tearing.
Several factors can weaken the aortic wall and make it prone to tearing. High blood pressure stands as the leading culprit, constantly battering the artery walls with excessive force over years or decades. Genetic conditions that affect connective tissue, such as Marfan syndrome or Ehlers-Danlos syndrome, can make the aortic wall inherently weaker and more likely to tear even at younger ages.
Trauma from car accidents or severe chest injuries can also cause immediate tears in the aortic wall.
Trauma from car accidents or severe chest injuries can also cause immediate tears in the aortic wall. Certain medical procedures, particularly those involving the heart or aorta, carry a small risk of causing dissection. Age-related changes in the artery wall, combined with conditions like atherosclerosis, gradually make the aorta more vulnerable to this catastrophic event.
Risk Factors
- High blood pressure, especially if poorly controlled
- Age over 60 years
- Male gender
- Marfan syndrome or other connective tissue disorders
- Bicuspid aortic valve (heart defect)
- Family history of aortic dissection
- Previous aortic surgery or procedures
- Cocaine or amphetamine use
- Pregnancy (rare but increased risk)
- Chest trauma from accidents or injuries
Diagnosis
How healthcare professionals diagnose Aortic Dissection:
- 1
When someone arrives at the emergency room with symptoms suggesting aortic dissection, doctors must act swiftly.
When someone arrives at the emergency room with symptoms suggesting aortic dissection, doctors must act swiftly. The classic presentation includes sudden, severe chest or back pain often described as tearing or ripping, sometimes accompanied by differences in blood pressure between the arms. Emergency physicians immediately order imaging tests while stabilizing the patient, as time is critical.

CT angiography has become the gold standard for diagnosing aortic dissection, providing detailed images of the aorta and clearly showing where the tear occurred and how far it extends.
CT angiography has become the gold standard for diagnosing aortic dissection, providing detailed images of the aorta and clearly showing where the tear occurred and how far it extends. This scan can be completed within minutes and gives surgeons the precise information they need. Transesophageal echocardiography may also be used, especially when CT isn't immediately available or when doctors need real-time images during treatment.

Blood tests help rule out heart attacks and assess organ function, while chest X-rays may show a widened aortic silhouette, though this finding isn't always present.
Blood tests help rule out heart attacks and assess organ function, while chest X-rays may show a widened aortic silhouette, though this finding isn't always present. Doctors must quickly distinguish aortic dissection from heart attacks, pulmonary embolism, and other conditions that can cause similar symptoms. The key lies in recognizing the characteristic tearing pain, unequal pulses or blood pressures, and getting immediate imaging to confirm the diagnosis.
Complications
- Aortic dissection can lead to several serious complications, depending on which organs lose blood supply as the tear extends.
- Stroke may occur if the dissection affects arteries supplying the brain, while kidney failure can develop if blood flow to the kidneys becomes compromised.
- Heart attack or acute heart failure may result when the dissection interferes with blood flow to the heart muscle or causes severe aortic valve leakage.
- The most feared complication is aortic rupture, where the weakened artery wall bursts completely, causing massive internal bleeding that is often fatal within minutes.
- Paralysis can occur if the dissection blocks arteries supplying the spinal cord, while limb ischemia may develop when blood flow to arms or legs is interrupted.
- With prompt treatment, many of these complications can be prevented or minimized, emphasizing the importance of immediate medical attention when aortic dissection is suspected.
Prevention
- While you can't prevent all cases of aortic dissection, managing blood pressure stands as the most effective preventive measure.
- High blood pressure is the leading risk factor, so maintaining readings below 130/80 mmHg through medication, diet, and exercise significantly reduces risk.
- Regular check-ups allow doctors to monitor blood pressure trends and adjust treatments as needed.
- For people with genetic conditions like Marfan syndrome or family histories of aortic disease, regular screening with imaging studies can detect early changes in the aorta before dissection occurs.
- These individuals may need preventive surgery if their aorta enlarges beyond safe limits.
- Avoiding cocaine and other stimulant drugs is essential, as these substances can cause sudden, dangerous spikes in blood pressure that may trigger dissection.
- Lifestyle modifications that support cardiovascular health help protect the aortic wall.
- This includes maintaining a healthy weight, exercising regularly (with appropriate restrictions for those with aortic conditions), managing stress, and avoiding smoking.
- People with known aortic conditions should work closely with cardiologists to develop personalized prevention strategies and monitoring schedules.
Treatment for aortic dissection depends on which part of the aorta is affected and requires immediate action.
Treatment for aortic dissection depends on which part of the aorta is affected and requires immediate action. Type A dissections, involving the ascending aorta near the heart, almost always need emergency surgery to prevent fatal complications like rupture or heart failure. Surgeons replace the torn section with a synthetic graft, often completing this life-saving procedure within hours of diagnosis.
Type B dissections, affecting the descending aorta, may be managed with intensive medical therapy if complications haven't developed.
Type B dissections, affecting the descending aorta, may be managed with intensive medical therapy if complications haven't developed. This approach focuses on strict blood pressure control using intravenous medications to reduce the force of blood against the weakened artery wall. Patients receive careful monitoring in intensive care units, where doctors can quickly detect any signs of worsening that might require surgical intervention.
Endovascular repair has revolutionized treatment for many Type B dissections and some complex Type A cases.
Endovascular repair has revolutionized treatment for many Type B dissections and some complex Type A cases. This minimally invasive approach involves threading a covered stent through blood vessels to seal the tear and redirect blood flow through the proper channel. The procedure often results in shorter recovery times and fewer complications compared to open surgery.
Long-term medical management becomes crucial after the initial emergency treatment.
Long-term medical management becomes crucial after the initial emergency treatment. Patients typically require lifelong blood pressure medications, regular imaging follow-ups, and lifestyle modifications. Beta-blockers and ACE inhibitors help reduce stress on the aortic wall, while regular CT scans monitor for any changes in the repaired or healing artery. Many people return to normal activities with proper medical management, though some restrictions on heavy lifting or intense physical exertion may apply.
Living With Aortic Dissection
Life after aortic dissection requires ongoing medical care but many people achieve excellent quality of life with proper management. Regular follow-up appointments every 3-6 months allow doctors to monitor the repaired aorta and adjust medications as needed. Blood pressure control becomes a lifelong priority, with most patients taking multiple medications to keep readings in the optimal range.
