EVAR & TEVAR (Aortic Stent Grafting)

What are EVAR and TEVAR?

EVAR (endovascular aneurysm repair) and TEVAR (thoracic endovascular aortic repair) treat aneurysms of the abdominal and thoracic aorta from within. A fabric-covered stent graft is compressed into a delivery catheter, introduced through the femoral arteries, and deployed inside the aneurysm — creating a new, reinforced channel for blood flow that excludes the aneurysm sac from circulation. Lifelong surveillance matters precisely because leaks around or through the graft (endoleaks) can re-pressurise the sac over time and are treatable when caught.

Advanced and complex repair

Aneurysms that involve branch arteries to the kidneys and bowel can often still be repaired by keyhole means using fenestrated, branched or physician-modified endografts — devices tailored with precisely positioned openings for each branch vessel. This is a specialised area of my practice.

What to expect

• Performed in a hospital hybrid operating theatre
• Most standard EVAR patients are home within a few days
• Lifelong imaging surveillance of the stent graft is part of the treatment, not an optional extra

Open repair still matters

Endovascular repair is not a universal answer. Anatomy, age and durability considerations mean open surgical repair remains the better operation for selected patients — and the honest discussion of both options is part of proper aortic care.
