Efficacy comparison of Solitaire AB and Enterprise stent-assisted embolization of intracranial wide-necked aneurysms / 中国脑血管病杂志

ABSTRACT

Objective To compare the effect of Solitaire AB and Enterprise stent-assisted endovascular embolization of intracranial wide-necked aneurysms. Methods The clinical data 218 patients with intracranial aneurysm treated with Solitaire AB stent or Enterprise stent in Guangdong General Hospital from January 2012 to December 2014 were analyzed retrospectively. Seventy patients were treated with Solitaire AB stents and 148 were treated with Enterprise stents. They were followed up after procedure (2 months to 2 years). The Raymond grade and the modified Rankin scale (mRS)scores were used to compare the efficacy of the 2 kinds of stents. Results There were no significant differences in patients before procedure in the Hunt-Hess grade (Z = 1. 550,P = 0. 121),Fisher grade (Z =1. 537,P =0. 124),aneurysm size (Z =0. 192,P =0. 848),and position (χ2 = 0. 337,P = 0. 736)between the 2 stent groups,while there were no significant differences in patients after procedure in the instant Raymond grade (Z = 0. 682,P = 0. 495), follow-up Raymond grade (Z = 0. 206,P =0. 837),and mRS score (P =0. 662)between the 2 stent groups. Further multivariate Logistic regression analysis showed that the stent type (Solitaire AB stent or Enterprise stent),Raymond grade follow-up grade (OR,0. 029 ,95% CI 0. 126 - 0. 199,P = 0. 661 ),and postoperative mRS score (OR,2. 000,95% CI 0. 204 - 19. 603,P = 0. 552)had no influence on the prognosis. Conclusions In the assisted embolization of intracranial wide-necked aneurysms using the Solitaire AB and Enterprise stents,the effects of both stents are good in the assisted embolization of intracranial wide-necked aneurysms.
