Total Arch Replacement With Frozen Elephant Trunk Versus Hemiarch Replacement in the Management of Acute Type A Aortic Dissection

Conventional open hemiarch replacement

E-vita® Open Neo is a hybrid stent graft system for aortic arch and descending thoracic aorta repair with Frozen Elephant Trunk Technique.

The Thoraflex Hybrid is a device system designed to repair a weakened and bulging section (aneurysm) and/or a tear in the lining (dissection) of the aorta behind the heart (aortic arch). The system includes a polyester graft section that reinforces a weakened section of the blood vessel, a connected stented section (nitinol wire frame on polyester graft material) that holds the artery open, and a delivery catheter that is used to place the device. The polyester graft and stented sections are coated with a protein substance taken from animal body parts (gelatin) to seal the implant and prevent blood from leaking out.
