Because the SETA endoprosthesis is balloon expandable, it has the following properties and advantages:
Adaptability to arterial necks: this characteristic allows it to be implanted in irregular arterial necks, conic, calcified, extremely short (less than 5 mm ) or angled (more than 60°).
Great radial force: the SETA endografts have a high radial force due to their design and configuration of the grooved metal skeleton. These factors let the tretment of severely stenotic arteries and/or critical angles.
Short term and long term stability: during the implant the balloon impacts the grooved tube against the arterial wall stabilizing the device in that position.
It doesn't dilate the arterial neck: Once the balloon is deflated and the slotted tube is placed against the wall, it stops expanding the artery avoiding the wall dilatation in the long run.
Also, some models of SETA Endograft can be applied to no aneurysmatic deseases.The great radial force during implant make them appropriate for the treatment of obstructive deseases. Post traumatic ruptures have also been treated, as well as ulcers and coarctactions of the aorta.
Scientific Studies and reports indicate that selfxpandable grafts show high rates of failure because of migrations and endoleaks. In the short, middle and long term. These inconvinients were observed even in those cases in which the instructions for its use were strictly followed (necks longer than 15 mm and angles smaller than 60°).Some authors suggest the structural conception of these devices is to blame.
