Understanding aortic surgery: when it’s needed and what to expect

Aortic surgery can sound daunting, but understanding why it might be necessary and what the procedure involves can help reduce anxiety and empower patients.

In this article, consultant cardiothoracic surgeon Mr Eltayeb Mohamed Ahmed explores the main reasons aortic surgery is performed, the different types of procedures available, and what patients can expect before, during, and after surgery.

What is the aorta and why it matters

The aorta is the body’s largest artery and carries oxygen-rich blood from the heart to the rest of the body. Because of its vital role, any problem that significantly affects the function or structure of the aorta can compromise blood flow and may require aortic surgery.

Common reasons for aortic surgery

There are several conditions affecting the aorta that may require surgical intervention, each with its own risks and treatment approach.

Aortic aneurysm

An aortic aneurysm occurs when a section of the aorta weakens and bulges. Small aneurysms are often monitored with regular scans, but larger or rapidly expanding aneurysms generally require aortic surgery to prevent rupture, which can be fatal.

Aortic dissection

An aortic dissection happens when the inner layers of the aorta tear, allowing blood to flow between the layers of the vessel wall. This is a medical emergency that often requires urgent aortic surgery to prevent complications such as organ damage or death.

Aortic valve disease

Sometimes the aortic valve, which regulates blood flow from the heart into the aorta, becomes narrowed (aortic stenosis) or leaky (aortic regurgitation). Severe aortic valve disease may require surgical repair or replacement, sometimes in combination with repair of the aorta itself.

Types of aortic surgery

Aortic surgery can be performed using different techniques depending on the location and severity of the problem, each with specific benefits and recovery considerations.

Open aortic surgery

Open aortic surgery involves making an incision in the chest to access the aorta directly. The damaged portion of the aorta may be replaced with a synthetic graft. Recovery can take several weeks, but open surgery is often the most durable long-term solution.

Endovascular surgery

Also known as TEVAR (thoracic endovascular aortic repair) or EVAR (endovascular aneurysm repair), this minimally invasive approach uses a stent graft delivered through a small incision in the groin. Recovery is usually faster, although not all aneurysms or dissections are suitable for this technique.

Valve-sparing procedures

In some cases, it is possible to repair the aortic root while preserving the patient’s natural valve. This approach reduces the need for lifelong blood-thinning medication required with mechanical valves.

Preparing for surgery

Before aortic surgery, patients undergo thorough assessments including imaging, blood tests, and consultations with anaesthetists and cardiologists. Optimising blood pressure, managing other health conditions, and stopping smoking helps reduce surgical risk.

Recovery and what to expect

Recovery after aortic surgery depends on the type of procedure performed. Open surgery may require a hospital stay of one to two weeks and several months of gradual rehabilitation. Endovascular procedures often allow patients to return home within a few days. Physical activity is initially limited, and follow-up scans are important to monitor the repaired aorta.

Living after aortic surgery

Many patients return to normal activities after recovery, although ongoing medical follow-up is essential. Lifestyle changes such as regular exercise, blood pressure control, and a heart-healthy diet contribute to long-term outcomes after aortic surgery.

Understanding why aortic surgery may be necessary and what the procedure involves allows patients to approach treatment with confidence. Early detection, thorough preparation, and careful follow-up are essential for the best results.
