Aortic dissection is a rare but life-threatening condition in which a tear develops in the inner layer of the aorta, the body's main artery, allowing blood to flow between the layers of the vessel wall. It typically causes sudden, severe pain and requires immediate emergency treatment, usually surgery.

What is Aortic Dissection?
Aortic dissection is a rare but life-threatening condition in which a tear develops in the inner layer of the aorta, the body's main artery, allowing blood to flow between the layers of the vessel wall. It typically causes sudden, severe pain and requires immediate emergency treatment, usually surgery.
Risk factors include high blood pressure, certain connective tissue conditions, and a family history of aortic problems. Because it progresses extremely quickly, recognising the symptoms and seeking emergency care immediately is critical to survival.
02 · Understand
Clinical context
This is one of the most time-critical medical emergencies
Aortic dissection can be rapidly fatal without emergency treatment, which is why any sudden, severe tearing chest or back pain should be treated as a life-threatening emergency without delay.
03 · Act
After Treatment: Non-Emergency Follow-Up
- 1You have a known risk factor, such as a connective tissue condition or family history, and would like to discuss monitoring
- 2You've been treated for aortic dissection and have questions about ongoing care
- 3You have poorly controlled high blood pressure and want to discuss reducing your cardiovascular risk
04 · Prevent & manage
Practical steps
There Is No Home Management — This Is Always an Emergency
Aortic dissection requires immediate emergency medical and surgical treatment — any suspected symptoms should prompt an immediate call to emergency services.
- 1Call emergency services immediately for suspected symptoms.Do not wait or attempt to drive yourself — this requires emergency transport and treatment.
- 2Manage blood pressure long-term.Well-controlled blood pressure significantly reduces the risk of aortic dissection over time.
- 3Know your family history.If aortic problems run in your family, discuss this with your doctor, as monitoring may be recommended.
- 4Attend follow-up care if you have a related condition.Conditions like Marfan syndrome carry a higher risk and benefit from regular monitoring.
