Purpose
To demonstrate 2 endovascular methods for successful intravascular stent
extraction.
Technique
In preparation for fenestrated endovascular aneurysm repair, renal artery
stents may be implanted for focal vessel stenosis at the ostium. In a recent
case, bilateral renal artery stents were deployed with >50%
protruding into the aortic lumen, thus rendering fenestrated endografting
impossible. Two techniques were employed to extract the stents. In the left
renal artery, the stent was extracted using an endovascular snare, but the
right renal artery stent could not be removed with this method. Instead, an
endoscopic forceps was advanced down a 16-F sheath, and the stent was
grasped, extracted, and released into the aneurysm sac. The endovascular
repair then proceeded in the usual fashion.
Conclusion
The need to remove a stent prior to endovascular aneurysm repair is not a
common problem encountered by most endovascular specialists; however, these
methods should be in their armamentarium should the need arise.
