As a pioneer in endovascular aortic repair, Cook is focused on therapies and technologies to treat aortic aneurysms in a minimally-invasive way and get patients back to living.

Endovascular graft placement: thoracic aortic aneurysms

Read about the grafts we have available today to treat thoracic aortic aneurysms.

What is Zenith Alpha™ Thoracic?

Zenith Alpha Thoracic is an endovascular graft— a flexible metal stent covered with fabric— that is designed to cover the artery wall so blood does not directly flow against the aneurysm. This can help prevent further aneurysm growth and possible rupture.

Benefits of being treated with a Zenith Alpha Thoracic graft

Zenith Alpha Thoracic is a minimally-invasive alternative to open surgical repair for a thoracic aneurysm. Zenith Alpha Thoracic helps prevent a thoracic aneurysm from growing or rupturing (a rupture is when the aorta bursts and causes life-threatening internal bleeding).

Risks of being treated with a Zenith Alpha Thoracic graft

Although Zenith Alpha Thoracic is designed to stop the aneurysm from getting worse, no surgery is without potential complications. Those complications could include the following:

  • Blood from the aorta could continue to leak into the thoracic aneurysm (This is also known as an endoleak).
  • The graft could move in the aorta.
  • The aneurysm could continue to grow or burst.
  • You could have a stroke.
  • You could become paralyzed.
  • You could have a heart attack.
  • You could get pneumonia.
  • You could experience kidney failure.
  • You could experience a bowel obstruction.
  • You could get an infection.
  • You could die.

Who should not be treated with a Zenith Alpha Thoracic graft?

The following people should not be treated with Zenith Alpha Thoracic graft:

  • Patients who are sensitive or allergic to stainless steel, tin, silver, polyester, polypropylene, nitinol, or gold.
  • Patients who have an infection in their bloodstream.

Following up with your doctor

It is very important to have regularly scheduled follow-up appointments with your doctor after receiving a graft. This is because it is possible for problems that do not cause noticeable symptoms to occur, and the long-term results of endovascular repair with grafts are not fully known. Your doctor needs to look at pictures of your aneurysm and graft on a regular basis.

Recommended follow-up includes checkups at:

  • 1 month
  • 6 months
  • 12 months
  • Yearly after 12 months

Remember, every patient is different, and your doctor knows you best. After reading the information on this site, make an appointment to talk to your doctor to help you make the right decision about any treatments or procedures.
