he first commercially available covered stent was
Corvita®, which was developed in Belgium by Jean
Pierre Becquemin. Covered stents have expanded the use
of endovascular procedures, they can be either with Dacron
(Wallgraft®) or polytetrafluoroethylene (PTFE), examples:
Solaris®, Viabahn®, iCast®, outside the United States
called Advanta® V12, Jostent® and Fluency®. They can
be balloon-expandable (iCast® or Advanta® V12) or self-
expandable (Solaris®, Viabahn®, Jostent®, Wallgraft®).
The treatment of vascular diseasehaschangeddramatically
during the last two decades. They are used mainly for
the treatment of traumatic arterial lesions, arteriovenous
fistulas or false aneurysms, peripheral aneurysms and,
more recently, for the treatment of obstructive vascular
disease of the aortoiliac and femoropopliteal sectors. To
treat visceral artery aneurysms (vaas) covered stents can
be useful, when the artery is not so tortuous and the vaas
are not intraparenquimal. The major technical limitations
to implant it in vaas are severe tortuosity, calcification or
sometimes small caliber arteries.There are a lot of available
stent grafts, we are getting experience, now, with the new
brazilian covered stent, Solaris®. This stent-graft is more
radiopaque than other conventional nitinol stents available
in Brazil, it is a flexible self-expanding stent graft with PTFE.
Those stents are a barrier to the ingrowth of neointimal
hyperplasia, sealing off the inflammatory surface, and thus
have the potential to inhibit restenosis. For the treatment
of vascular trauma, hemorrhage, aneurysmal disease, or
even for stent grafts used for aortic aneurysms, several
minimally invasive therapies are available. This video gives
an overview of our experience in the currently available
covered stents and they’re useful.
