Gateway-Wingspan stent system assisted angioplasty for treatment of chronic basilar artery stenosis / 中国脑血管病杂志

ABSTRACT

Objective: To assess the feasibility and safety of Gateway-Wingspan stent system assisted angioplasty for treatment of basilar artery stenosis. Methods: The operative strategy, efficiency, successful rate, the degree of stenosis and periprocedural neurological complications were analyzed retrospectively in 20 patients after Gateway-Wingspan stent system assisted angioplasty for treatment of chronic basilar arterial stenosis. Results: 20 patients of basilar artery stenosis using stent assisted angioplasty were implanted 20 Wingspan stents. The stent implantation was successful in all patients. The mean degree of stenosis decreased from (79.0 ± 6.0)% before the procedure to (13.0 ± 3.4)% after stenting. One patient advent brain stem infarction because of AICA occlusion. During the follow-up of 1, 3 and 6 month, according to Malek scale, twelve patients (60%) belonged to scale 1, two patients (10%) belonged to scale 3, and one patient (5%) belonged to scale 1. All of 15 patients were in stable condition. Among them, the treatment efficiency of twelve patients were very successful. In addition, 5 patients treatment effect was very good in the early postoperative period, but the treatment effect was gradually decreased. Among them, 3 patients (15%) belonged to scale 1 after one month, but belonged to scale 2 after three months. In addition, 2 patients (10%) belonged to scale 2 in 1, 3 month, but belonged to scale 2 after six months. Conclusion: Gateway-Wingspan stent system assisted angioplasty is safe and feasible for treatment of basilar artery stenosis.
