BACKGROUND:: Endovascular treatment of intracranial aneurysms can be technically difficult when the neck is wide. The Solitaire AB stent, the only fully retrieved stent, assists in the coiling of wide-neck intracranial aneurysms.
OBJECTIVE:: To evaluate the mid-term angiographic follow-up of wide-necked aneurysms treated with the Solitaire AB stent.
METHODS:: SOLARE is a consecutive, prospective study conducted in 7 European centers. A core laboratory evaluated the postoperative and mid-term (6 month ± 15 days) angiographic results by using the Raymond classification Scale. "Recanalization" was defined as worsening, and "progressive thrombosis" was defined as improvement on the Raymond scale.
RESULTS:: The mean width of the aneurysm sac was 7.5 mm, and the mean diameter of the aneurysm neck was 4.7 mm. Angiographic mid-term follow-up was obtained in 55 of 65 aneurysms (85.9%). Complete occlusion was achieved in 33 aneurysms (60%); neck remnant was seen in 16 aneurysms (29.1%) and aneurysm remnant in 6 aneurysms (10.9%). Of 55 aneurysms, recanalization was observed in 8 aneurysms (14.5%), and progressive thrombosis was observed in 17 aneurysms (30.9%). No bleeding or rebleeding was observed during the follow-up period.
CONCLUSION:: Stent-assisted coiling of wide-necked intracranial aneurysms is safe and effective with the Solitaire AB stent at 6-month follow-up. Angiographic results improve with time due to progressive thrombosis of the aneurysm.
