Introduction
An aortic dissection is one of the most serious cardiovascular emergencies. It occurs when a tear develops in the inner lining of the aorta, allowing blood to separate the layers of the vessel wall. Without timely diagnosis and treatment, the condition can reduce blood supply to vital organs or cause the aorta to rupture. Early recognition, rapid imaging, and treatment by an experienced cardiovascular surgeon greatly improve outcomes.
Understanding the Aorta
The aorta is the body’s largest artery and carries oxygen-rich blood from the heart to the brain, arms, abdomen and legs. Because every major organ depends on healthy blood flow through the aorta, diseases affecting this artery require urgent specialist care.
What is Aortic Dissection?
Unlike a heart attack, which is caused by blocked coronary arteries, an aortic dissection begins with a tear inside the wall of the aorta. Blood enters this tear and creates a false channel within the wall. As the dissection progresses, blood flow to the brain, kidneys, intestines or legs may become compromised.
Symptoms
Patients often describe the pain as sudden, severe, tearing or ripping. Symptoms may include chest pain, back pain, abdominal pain, fainting, breathlessness, sweating, weakness of an arm or leg, difficulty speaking or loss of vision. Any of these symptoms require immediate emergency evaluation.
Causes and Risk Factors
The most common risk factor is long-standing uncontrolled high blood pressure. Other causes include aortic aneurysm, bicuspid aortic valve, inherited connective tissue disorders such as Marfan syndrome, ageing, smoking, high cholesterol, chest trauma and a family history of aortic disease.
Diagnosis
Doctors combine a physical examination with advanced imaging. CT angiography is the preferred emergency investigation because it clearly shows the location and extent of the dissection. Echocardiography, MRI and chest X-ray may also be used depending on the patient’s condition.
Treatment
Treatment depends on the location of the tear. Type A dissections usually require emergency open surgery to replace the damaged section of the aorta and, if necessary, repair or replace the aortic valve or root. Selected Type B dissections may initially be treated with blood pressure medication, while complicated cases are managed using TEVAR (Thoracic Endovascular Aortic Repair), a minimally invasive stent-graft procedure.
Recovery and Prevention
Recovery includes lifelong blood pressure control, regular CT or MRI follow-up, prescribed medications, heart-healthy nutrition, smoking cessation and avoidance of heavy weightlifting. Routine follow-up with an aortic specialist helps detect future problems early.
