Are aortic stent grafts MRI safe?
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.
Is Evar MRI safe?
After being implanted with the abdominal stent graft manufactured by Medtronic, it is still safe to have MRI procedures, under certain conditions. MRI information is provided on your implanted device ID card. Show this ID card to your healthcare providers.
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.
Are sternal wires safe for MRI?
Cardiac MRI is safe with joint replacements, coronary stents, ASD/PFO closure devices, sternal wires and most prosthetic heart valves. Patients with a history of metallic implants / shrapnel / prior neurosurgical clip placement are all individually evaluated prior to MRI.
Are endovascular coils MRI safe?
In this large, retrospective review of patients with implanted SSEC undergoing MRI, there were no reported adverse events. These findings support the recent change by Cook Medical Inc. of their standard embolization coils from a designation of magnetic resonance unsafe to conditional.
What is the difference between stent and graft?
Blood Vessels Theoretically, the graft creates a barrier to exclude diseased arterial wall and provides a smooth flow conduit, while the stent support affixes the graft and may enhance luminal patency by resisting external compression.
What is the purpose of an aortic endograft?
The graft is then opened up inside the aorta and held in place with metal hooks and stents rather than sutures (stitches). By tightly sealing the area with your artery above and below the aortic aneurysm, the graft allows blood to pass through it without pushing on the aneurysm.
