EP22 The wallaby avenir coil system: Initial experience with use of Avenir coils for treatment of intracranial aneurysms

Introduction

The Wallaby Avenir coil system is a novel generation of platinum embolic coil system indicated for endovascular embolization of intracranial aneurysms and other neurovascular abnormalities. The coils come in framing, filling and finishing types in different sizes both in helical and three dimensional shapes. The unique feature of this coil is that it does not need a detacher and can be mechanically detached with fingers once optimal coil position is achieved. This is a new move in technology that has not been recommended for reliable detachment in other pre-existing coil embolization systems.

Aims

To assess Wallaby Avenir coil embolization system detachment reliability, summarise intra-procedural outcomes in the treatment of intracranial aneurysms following its introduction in a tertiary centre.

Methods

This prospective study reviewed total of 11 patients with 10 intracranial aneurysms and 1 carotico-cavernous fistula between January 2021 and May 2021. 7 acute and 4 elective aneurysms were treated. All patients with intracranial aneurysms treated with Avenir coil system were included in the study.

Results

The average age of the cohort was 59.5 years. 85.8% (67/78) coils Avenir coils detached reliably. Good Raymond-Roy occlusion was achieved in 91% (10/11) aneurysms in the immediate post procedural run. There was no mortality or neurological deterioration in the series. There was no intraprocedural aneurysmal rupture from Avenir coils.

Conclusions

The Wallaby Avenir coil system have excellent intraprocedural safety prolife with no procedure related mortality or morbidity and good postprocedural aneurysm occlusion rates.
