Can I have an MRI with an aortic stent?

MRI Safety and Compatibility: Non-clinical testing has demonstrated that the Endurant II Stent Graft is MR Conditional. It can be scanned safely in both 1.5T & 3.0T MR systems under certain conditions as described in the product Instructions for Use.

What is a Zenith Flex AAA Endovascular graft?

The Zenith Flex AAA Endovascular Graft with the Z-Trak® Introduction System and ancillary components are indicated for the endovascular treatment of patients with abdominal aortic or aorto-iliac aneurysms having morphology suitable for endovascular repair.

Are stents contraindicated in MRI?

Coronary artery stents, prosthetic cardiac valves, metal sternal sutures, mediastinal vascular clips, and epicardial pacing wires are not contraindications for MRI, in contrast to pacemakers and implantable cardioverter-defibrillators. Appropriate patient selection and precautions ensure MRI safety.

What are stent grafts?

Find a Doctor. An endovascular stent graft is a fabric tube, supported by a metal mesh, called a stent that is used to support a weak spot in an artery, called an aneurysm – in many cases, an abdominal aortic aneurysm.

What are stent grafts made of?

The stent graft is a tube made of a thin metal mesh (the stent), covered with a thin polyester fabric (the graft). The tube is collapsed so it is narrow and can fit through your blood vessel. When the stent graft reaches the aorta, it is opened up and fastened in place.

What is an aortic stent graft?

The stent graft is a tube made of a thin metal mesh (the stent), covered with a thin polyester fabric (the graft). This stent graft is opened inside the aorta and fastened in place. The stent graft stays in place, and blood flows through it. It protects that part of the aorta, and prevents the aneurysm from bursting.

How long does a stent graft last?

Current generation stent grafts correlated with significantly improved outcomes. Cumulative freedom from conversion to open repair was 93.3% at 5 through 9 years, with the need for prior reintervention (OR, 16.7; P = 0.001) its most important predictor. Cumulative survival was 52% at 5 years.

Are Xience stents MRI safe?

Non-clinical testing has demonstrated that the XIENCE V stent, in single and in overlapped configurations up to 68 mm in length, is MR Conditional. It can be scanned safely under the conditions in the Instructions for Use.

What kind of endovascular graft does zenith use?

Zenith® Fenestrated AAA Endovascular Graft Distal Bifurcated Body Grafts. The Zenith Fenestrated AAA Endovascular Graft with the H&L-B One-Shot™ Introduction System is indicated for the endovascular treatment of patients with abdominal aortic or aorto-iliac aneurysms having morphology suitable for endovascular repair.

Is it safe to scan a zenith stent?

Like other metallic stents it is considered MR Conditional at 1.5T and 3.0T. Although safe to scan as long as conditions are followed, some stents like the Zenith produce a substantial susceptibility artifacts making assessment of stent patency by MRI difficult.

Are there any stents that are MR unsafe?

To my knowledge, there are no currently implanted stents that are considered MR Unsafe. In the past the Zenith AAA stainless steel stent-graft was placed in this category by its manufacturer (Cook), but this restriction has now been lifted. Like other metallic stents it is considered MR Conditional at 1.5T and 3.0T.
