摘要

Purpose

The Woven EndoBridge is a device for endovascular embolization of intracranial aneurysms. The aim of this study is to re-evaluate this treatment method regarding its safety and efficacy and to compare it with the results of alternative treatment strategies (clipping, coiling, etc.) and their outcome known from the literature.

Methods

Forty-four intracranial aneurysms treated with the Woven EndoBridge were retrospectively identified in a clinic for diagnostic and interventional neuroradiology. The average aneurysm height was 7.1 mm, and the average width was 5.8 mm. Further the average neck diameter (3.6 mm) and the average dome-to-neck ratio (1.6) were determined. Both ruptured and non-ruptured aneurysms were included in this study. Occlusion was assessed using the WEB Occlusion Scale immediately after the intervention and after three, six and twelve months follow-up.

Results

In 11% of cases (n = 5), implantation of the Woven EndoBridge failed technically. In two patients, a thromboembolic event occurred during the intervention without consequential damage. During the observation period of twelve months, none of the study participants died because of the intervention. After twelve months, 95% of the treated aneurysms (n = 20) showed adequate occlusion.

Conclusion

Compared to other treatment strategies (clipping, coiling etc.) and their complication rates known from other studies, our results suggest that the Woven EndoBridge is a safe treatment option. Regarding the angiographic results, the Woven EndoBridge achieves occlusion rates which are comparable with those of intravascular flow diverters, but without the need of dual anti-platelet-aggregation therapy.
