Aortic arch replacement is a highly specialised operation performed when disease affects the part of the aorta that gives rise to the blood vessels supplying the brain and upper body.
Conditions affecting the arch are often complex and may include aneurysm formation, aortic dissection, or progressive enlargement associated with inherited or connective tissue conditions.
Because of the arch’s close relationship to the circulation of the brain, surgery requires detailed planning and specialised techniques to protect blood flow to the brain during the operation.
The aim of surgery is to treat the disease safely, reduce the risk of future aortic complications, and maintain long-term stability of the aorta.
The aortic arch is the curved portion of the aorta that connects the ascending and descending aorta. It gives rise to the arteries supplying blood to the brain and upper body.
Aortic arch replacement involves removing the diseased segment of the aorta and reconstructing it using a synthetic graft. The arteries supplying the brain are carefully reattached to restore normal blood flow.
In some patients, arch surgery is performed as an isolated procedure. In others, it forms part of a more extensive repair involving the aortic root, ascending aorta, or descending thoracic aorta.
Some patients may also have had previous aortic surgery, which requires additional planning.
Not all arch enlargement requires immediate surgery.
The timing of surgery depends on:
The operation is performed under general anaesthetic using cardiopulmonary bypass.
During part of the operation, the body is cooled and the circulation is temporarily paused, while blood flow to the brain is maintained.
The diseased portion of the arch is removed and replaced with a synthetic graft. The arteries supplying the brain are then carefully reattached.
In selected patients, the procedure may include a frozen elephant trunk, allowing treatment to extend into the descending aorta and support longer-term aortic management.
Because patterns of aortic disease vary, the operation is tailored carefully to the individual patient and the extent of disease.
Patients are monitored in a cardiac intensive care unit following surgery, with assessment of neurological status.
Hospital stay is typically one to two weeks, depending on procedural complexity and recovery.
Gradual mobilisation begins under supervision once medically stable.
Ongoing imaging surveillance is essential to monitor the repair and assess the remaining aorta over time.
Recovery continues over several weeks at home, with gradual improvement in strength and stamina.
Mr Ahmed Othman is a Consultant Cardiac and Aortic Surgeon with a specialist practice focused on complex aortic surgery, including advanced aortic arch reconstruction.
His work involves highly specialised procedures requiring careful planning, technical precision, and a structured long-term approach to aortic disease.
Each case is assessed individually, with detailed imaging review and clear discussion of operative strategy and long-term management.
Specialised techniques are used to maintain blood flow to the brain throughout the operation.
This includes controlled management of circulation and continuous monitoring to ensure the brain remains protected during the procedure.
Yes. Aortic arch replacement can be combined with other procedures, particularly where disease affects other segments of the aorta, such as the aortic root or descending aorta.
Aortic arch surgery is a complex operation involving the part of the aorta that supplies blood to the brain, and requires specialised techniques to maintain cerebral circulation during the procedure.
All major cardiac and aortic procedures carry recognised risks. These are assessed based on your individual condition, overall health, and the extent of aortic disease. The aim is to proceed at a stage where the balance of risk and benefit is clearly understood.
Your individual risk profile is discussed in detail during consultation, including the specific considerations relevant to
Recovery after aortic arch surgery reflects the complexity of the procedure, particularly as it involves the blood vessels supplying the brain.
Following surgery, you are monitored closely in a cardiac intensive care unit, including assessment of neurological function. As recovery progresses, you are transferred to a specialist ward where mobilisation and rehabilitation begin.
Most patients spend around one to two weeks in hospital, followed by several weeks of recovery at home. Improvement in strength and stamina is gradual.
Mr Ahmed Othman will see you daily following surgery until you are safely discharged, and follow-up continues after you return home.
