Endovascular Treatment of Small Wide-Neck Bifurcation Aneurysms with Single Solitaire AB Stent Technique.

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 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.
