Abstract：Objective To compare the safety and effectiveness of Solitaire stent-assisted coil embolization with Neuroform stent-assisted coil embolization for ruptured wide-necked intracranial aneurysms(RWN-IA).Methods A retrospective analysis was performed on the clinical data of 118 patients with RWN-IA who underwent stent-assisted embolization from September 2017 to October 2022.Among them,45 patients received Solitaire stents and 73 received Neuroform stents.Results All stents were successfully released,without displacement of stents and coils prolapsing into the parent arteries.Postoperative immediate angiography showed that the complete occlusion rate in the Solitaire group(84.4%,38/48)was not statistically different from that(86.3%,65/73)in the Neuroform group(P=0.683).One case in the Solitaire group experienced intraoperative aneurysm rupture,while one case in the Neuroform group experienced local cerebral ischemia after the procedure;both patients were discharged without obvious neurological deficit.At discharge,the good outcome rate in the Solitaire group(86.7%,39/45)was not statistically different from that(87.7%,64/73)in the Neuroform group(P=0.874).Among the 107 patients(90.7%,107/118)who received clinical follow-up(range 102～458 d;mean 145 d),the good outcome rate at the last follow-up in the Solitaire group(86.0%,37/43)was not statistically different from that(85.9%,55/64)in the Neuroform group(P=0.323).Among the 88 patients(74.8%,88/118)who received imaging follow-up(range 213～817 d;mean 264 d),the complete occlusion rate at the last follow-up in the Solitaire group(92.1%,35/38)was not statistically different from that(90.0%,45/50)in the Neuroform group(P=0.670).Conclusions For RWN-IA,the use of Solitaire and Neuroform stents for assisted embolization therapy is safe and effective,with similar safety and efficacy.
