aneurysmal recanalization). Two of those recurrent aneurysms were retreated by coilembolization. The overall directly procedural-related complication rate was 4,7%, including one death. Seven cases of in-stent-stenosis (12,3%; morbidity n=0) were detected on long-term follow-up with 6 of them when using the kissing-Y stenting technique. Conclusions Endovascular treatment of various complex intracranial aneurysms using the Acandis Acclino stent systems is safe and efficient with high aneurysm occlusion rates combined with low complication rates at long-term follow-up. Overall, rates of in-stent-stenosis are low but seem to depend on the treatment technique (single stent-assisted versus kissingY stenting with coiling).
