Abstract

OBJECTIVE
Solitaire AB stent-assisted coiling facilitates the endovascular treatment of wide-necked intracranial aneurysms. We present our experience of coiling the micro-aneurysms of wide-neck with Solitaire AB stent assisting in a single center.
METHODS
Thirty-one Solitaire AB stents were used to treat via endovascular approach patients with 31 wide-neck micro aneurysms in a single center in China. Technical and clinical complications were recorded. Modified Rankin Scale was used to evaluate the patients' conditions via clinic and telephone follow-up.
RESULTS
The mean width of aneurysm sac was 2.30±0.42 mm, and the mean diameter of aneurysm neck was 2.83±0.48 mm. Complete occlusion was achieved in 28 aneurysms (90.32%); neck remnant was seen in 3 aneurysms (9.68%). Technical and clinical complications related to the procedure were encountered in four patients (12.5%). Two patients died (6.25%). No patient had a permanent deficit.
CONCLUSION
Solitaire AB stent was a safe and efficiency tool in assisting coiling of micro aneurysms with wide neck, but may be not suitable for a blaster-like one. Mid- and long-term follow-up will be required to elucidate the impact of the Solitaire AB stent on recanalization rate.
