Treatment of intracranial aneurysms. Reconstruction of the parent artery with flow-diverting (Silk) stent
Treatment of intracranial aneurysms. Reconstruction of the parent artery with flow-diverting (Silk) stent:
Abstract
Introduction
Since the flow diverters (FDs) have been introduced it is possible to treat aneurysms that are considered difficult or impossible
to treat with usual endovascular or surgical methods. It is still uncertain which aneurysms are suitable for this new treatment.
We present the periprocedural complications, immediate result, late complications, imaging follow-up at 6 and 12 months and
clinical follow-up at 2–23 months.
to treat with usual endovascular or surgical methods. It is still uncertain which aneurysms are suitable for this new treatment.
We present the periprocedural complications, immediate result, late complications, imaging follow-up at 6 and 12 months and
clinical follow-up at 2–23 months.
Results
Periprocedural complications were seen in four treatments (17%). However, none of these had clinical consequences. Mortality
and morbidity rates were 1 of 22 (5%) and 1 of 22 (5%), respectively. Clinical outcome was unchanged in 16 patients (72%),
3 patients improved (14%) and 3 patients worsened (14%). The end-of-procedure angiography did not show complete occlusion
of any of the aneurysms, but at 6 months follow-up angiography, 17 of 25 aneurysms (68%) were completely occluded, and at
12 months, 18 of 21 aneurysms (86%) were occluded.

Conclusion
The effect of the Silk FD in terms of occlusion of the aneurysms seems to occur mainly during the first 6 months after placement
but continues during the following time. Most delayed complications occur immediately after discontinuing the anticoagulation
medication. Considering the complexity of the aneurysms treated, the rate of complications is acceptable.

This is a small patient group who underwent flow diversion with the SILK stent. 1/22 died and 1/22 had clinical deficits. 18/22 aneurysms occluded at 1 year. I do not think these results are really very good
