AbstractIntroduction Solitaire AB stent-assisted coiling facilitates the endovascular treatment of wide-necked intracranial aneurysms. Solitaire Aneurysm Remodeling is the first prospective, consecutive, European multicentric study whose main objective was to evaluate the safety, short-, and long-term efficacy of the Solitaire AB stent. This first analysis is focused on the short-term results.
Methods After exclusion of one patient, 66 Solitaire AB stents were used to treat via endovascular approach 64 aneurysms (63 patients) in seven European centers. Technical and clinical complications were recorded. A core laboratory evaluated the angio-graphic efficacy by using the Raymond classification scale.

Results The mean width of aneurysm sac was 7.5 mm, and the mean diameter of aneurysm neck was 4.7 mm. Complete occlusion was achieved in 27 aneurysms (42.2 %); neck remnant was seen in 25 aneurysms (39.1 %) and aneurysm remnant in 12 aneurysms (18.7 %). Technical and clinical complications related to the procedure were encountered in eight patients (12.7 %). Postprocedural modification of the clinical status was observed in one patient (1.6 %). No patients died (0 %); one had a permanent deficit (1.6 %), and one had a transient deficit (1.6 %). Treatment-related mortality was 0 %, and permanent morbidity was 1.6 %.
Conclusion The Solitaire AB stent has an excellent rate of technical success navigation with the absence of dislodgement. The safety and short-term efficacy are comparable to those previously...
