Aortic Surgery

The aorta is the main artery carrying blood from the heart to the rest of the body. Because it carries the full force of every heartbeat, disease of its wall is potentially life-threatening. Aortic surgery replaces or reinforces the diseased segment before it fails, or repairs it urgently when it already has.

The two main problems

• Aneurysm — the wall weakens and the vessel widens over time. Aneurysms are usually silent and are often found incidentally on a scan done for another reason. Risk of rupture rises with diameter and with the rate at which it is growing.
• Dissection — the inner lining tears, and blood is driven into the wall itself, splitting its layers. This is a surgical emergency. It typically causes sudden severe chest or back pain, often described as tearing, and requires immediate assessment.

When surgery is advised

For an aneurysm, the decision balances the risk of rupture against the risk of operating. Diameter is the main measure, but it is not the only one: growth rate, family history, the presence of a bicuspid aortic valve, connective tissue disorders such as Marfan syndrome, and whether the aortic valve also needs treatment all shift the threshold. A smaller aneurysm in a patient with a connective tissue disorder may warrant earlier surgery than a larger one in a patient without.

Types of operation

Treatment depends on which segment is involved. Disease of the aortic root and ascending aorta is treated by open replacement with a graft, sometimes combined with valve repair or replacement, and in suitable cases with a valve-sparing root replacement that preserves the patient's own valve. Arch disease is more complex and requires techniques to protect the brain during the repair. Disease further down the descending aorta may be treatable with a stent graft placed from within the vessel.

Blood pressure is part of the treatment

Strict blood pressure control is central both before and after surgery. Every beat against a weakened or repaired wall matters. Patients are usually advised to avoid heavy straining and maximal weight lifting, to continue prescribed antihypertensive medication without interruption, and to stop smoking completely — smoking accelerates aneurysm growth.

Screening relatives

Some aortic disease runs in families. Where a patient has an aneurysm at a young age, a bicuspid valve, or a known connective tissue disorder, screening first-degree relatives with imaging can identify silent disease long before it becomes dangerous.
