Abstract：
PURPOSE:The low-profile Acandis Acclino is a self-expandable nitinol microstent for stent-assisted coiling of intracranial aneurysms. This article reports long-term clinical and angiographic outcome in a multicenter setting. METHODS:In this study 98 consecutive patients (mean age 55.4 ± 13.5 years) were treated with the Acclino for 98 aneurysms (28 unruptured, 20 recurrent, 50 ruptured) at 3 German tertiary care centers within a 6-year period. The technical success, complications, clinical outcome and angiographic results were retrospectively analyzed. RESULTS:The technical success rate was 100% with immediate complete occlusion achieved in 89.8% of the patients. Among 65 patients (66.3%) available for a 6‑month follow-up, complete and near-complete occlusion rates were 92.3% and 98.5%, respectively. In 38 patients (38.8%) with long-term follow-up (mean: 21 months), complete and near-complete occlusion were achieved in 81.2% and 89.5%, respectively. Aneurysm recurrence between mid-term and long-term follow-up was observed in 14.3%. The retreatment rate was 11.3%. There were three thromboembolic events (3.1%), of which one resulted in ischemic stroke (1.0%). For unruptured aneurysms, the procedural and device-related morbidity rates were 2.1% and 0%, respectively. CONCLUSION:In the present study, the Acclino was associated with a low risk of thromboembolic complications and high aneurysm occlusion rates at long-term follow-up. Due to incomplete angiographic follow-up in this series, prospective studies will be necessary to confirm the results.
