Background And Purpose:
We present our experience in using the single Solitaire AB stent for small wide-neck bifurcation aneurysms (WNBAs).
Materials And Methods:
During 18 months, 20 small (the largest width <10 mm) WNBAs were treated with the single Solitaire AB stent-assisted coiling. The patients were 12 women and 8 men, with a mean age of 52 years (range: 36-66 years). The mean aneurysm size was 4.2 mm (2-9 mm) and mean neck size was 3.9 mm (2-9 mm). Results at follow-up were graded as complete occlusion, neck remnant, or residual aneurysm.
Results:
All 20 small WNBAs were adequately occluded after a single Solitaire AB stent placement. There were no procedural ruptures and no thromboembolic complications occurred. Two patients developed a transient neurological deficit. In 20 patients with angiographic follow-up at 6 months, 16 (80%) aneurysms remained adequately occluded. Clinical follow-up in the 20 patients revealed mRS 0-2 in all.
Conclusions:
Single Solitaire AB stent-assisted coil embolization for small WNBAs was safe and effective.
