Endografts / Cardiac Patho test 2/2 Flashcards
Introduction of __ ___ ___ to assure the proper placement of the endovascular graft in the aortic arch covering the origin of the left subclavian artery.
right brachiofemoral wire
Insertion of the system over the ___ ___ ____ . The system is advanced to the target landing zone and it is deployed several millimeters proximally. Stamp position is verified by angiography.
stiff guide wire
The endograft is delivered by _______________________
until the graft cover separates from the tip and the first stents are deployed. At this point angiography is performed to verify the position of the graft.
turning the delivery system several times
The delivery system is removed by depressing the ______ and the handle is pulled back to retract the tip into the graft cover. After establishing a smooth transition between the tip and graft cover the entire delivery system is removed.

What device has the great advantage of flexibility and tapering. This is particularly useful in dissecting aneurysms where the same lumen throughout the system might result in folding of the dissection, and where the proximal part of the aneurysm, distal to the subclavian artery, usually has the largest diameter.
The Endofit device
Aortic neck diameters range from ?
In order to qualify for the Gore Tag implantation the proximal neck should be at least
23mm - 37mm
20mm
Pathologies where the endografting can be used in the thoracic aorta.
- atherosclerotic aneurysms
- chronic dissection with expansion
- acute traumatic transection of the aorta
- coarctation repair with development of a pseudoaneurysm
