Stryker Neuroform Atlas Instrucciones De Uso página 8

Q: A loop, or several loops, of a coil are protruding through the interstices of the
stent, and I am unable to reposition it. What should I do?
A: If the risk of leaving part of the coil in the parent vessel is unacceptable, place
a second stent inside the first stent to pin the herniated coil portion against
the wall of the vessel. Three-dimensional angiography using an orthogonal
view (i.e., "down the barrel") may be helpful to assess whether or not a coil
loop is inside the lumen of the stent, in the parent vessel, or between the wall
of the vessel and the stent. Strict attention to heparinization and antiplatelet
medication is important.
Q: I have accidentally started to deploy the stent, but it is not in the location that
I wanted. What should I do?
A: In general, the safest course of action is not to try repositioning the stent.
Rather, continue to deploy the stent where it is and then deploy a second
stent at the desired location. Safely deploying a stent – even in an undesired
location – will minimize vascular injury. Animal studies have demonstrated
that the stent endothelializes in less than 30 days.
Q: I misjudged the positioning of the stent and have deployed it with one end
adjacent to the aneurysm rather than in the normal part of the parent vessel.
What should I do?
A: Remove the stent delivery wire from the microcatheter while maintaining the
position of the microcatheter. Insert and deploy a second Neuroform Atlas™
Stent to the normal portion of the parent vessel (in a telescoping fashion). The
second stent should be of the same diameter or larger than the first.
