Introduction The ARTISSE device is a relatively new intra-saccular embolisation device that has been designed to offer advantages over other existing intra-saccular treatment options for wide-necked aneurysms. We used it since the mid 2023 in Montpellier University Hospital for intracranial wide neck aneurysm embolisation

Aim of Study The goal of this study is to evaluate technical success, procedural safety, and effectiveness of ARTISSE device for the treatment of intracranial wide-neck aneurysms.

Methods 29 patients with intracranial wide-neck aneurysms were enrolled at Montpellier University Hospital. Before&after device deployment angiograms, post-procedure CT scan, and 6-month follow-up MRI were all reviewed. Utilisation of sim&size technology was done for better device sizing

Results 28 patients received the ARTISSE implant (technical success=96.5%) . Only in one patient the ARTISSE treatment was unsuccessful due to displacement of ARTISSE to the parent artery and it was replaced by flow diverter device. No primary safety event during or after procedures in all 29 patients.

Conclusion According to our experience, the ARTISSE device can be used to treat intracranial wide neck aneurysms with a high level of procedural safety and a high degree of technical success. Larger series with long-term follow-up are necessary to confirm our experience with ARTISSE device.
