What is the Zenith® Dissection system?

Zenith Dissection is an endovascular system containing both a covered and a bare metal stent. The covered stent graft is a flexible stent covered with fabric designed to help cover the dissection tear, while the bare metal stent provides support to the dissected aorta. The Zenith Dissection system may help slow or prevent continued dissection, while maintaining blood flow to the vessels.

Benefits of being treated with the Zenith Dissection system

Zenith Dissection helps prevent aortic rupture, when the aorta bursts and causes life threatening internal bleeding, or malperfusion, reduced blood flow to important organs like the kidneys and gut. The Zenith Dissection system is a minimally-invasive alternative to open surgical repair.

Risks of being treated with the Zenith Dissection system

Although Zenith Dissection is designed to help the aorta heal, no surgery is without complications. Those complications could include the following:

  • Blood from the aorta could continue to leak into the dissection.
  • The graft and/or stent could move in the aorta.
  • The blood vessel wall could completely tear, causing serious internal bleeding.
  • The dissection could continue to grow or extend further down the aorta.
  • You could have malperfusion— reduced blood flow to important organs like the kidneys and gut.
  • You could have complications in your lungs, kidneys heart, blood vessels, or stomach.
  • You could have a stroke.
  • You could become paralyzed.
  • You could die.

Who should not be treated with the Zenith Dissection system?

The following people should not be treated with the Zenith Dissection system:

  • Patients who are sensitive or allergic to stainless steel, 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 or stent. 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 and stents are not fully known. Your doctor needs to look at pictures of your dissection and graft and/or stent 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.
