Aneurysm Repair

An aortic aneurysm damages the aorta and may create a life-threatening condition. Most people with a thoracic aortic aneurysm have open-chest surgery, but sometimes a less-invasive procedure called endovascular surgery can be done.

How and why it is done?

Endovascular aneurysm repair involves inserting a graft within the aneurysm through small groin incisions using X-rays to guide the graft into place. A surgeon removes the damaged part of the aorta and replaces it with a synthetic fabric tube. This tube is called a graft. It functions as a new lining for the artery so blood can safely pass through.

A successful aneurysm surgery prevents rupture or blocking due to aneurysms and faster recovery is seen. Full recovery takes between 3 and 6 months after open surgery and 2 to 4 weeks after endovascular repair. The speed of recovery will also be affected by age and general fitness.

Frequently Asked Questions

How big can an aneurysm get before it bursts?

An aneurysm occurs when a portion of the aorta has enlarged to at least 1.5 times its normal size. Aortic aneurysms less than 4 cm in size have a low chance of bursting, but aneurysms more than 5.5 cm in diameter have an increasing chance of rupturing in the next year. 

What causes an Aneurysm?

Any condition that causes the artery walls to weaken can bring one on. The most common causes are atherosclerosis and high blood pressure. Deep wounds and infections can also lead to an aneurysm.

What is the success rate of aneurysm surgery?

Surgical procedures for the repair of abdominal aortic aneurysms have a high success rate, with more than 95 percent of patients making a full recovery.
