Ischemic Complications after Carotid Artery Stenting Associated with Stent Cell Design: Closed-cell versus Open-cell Stents

抄録

Objective: The influence of stent cell design on cerebral embolism after carotid artery stenting (CAS) is not well understood. The purpose of this study was to evaluate the influence of stent cell design on the incidence of periprocedural cerebral embolism in tailored CAS.

Materials and Methods: A total of 114 symptomatic and asymptomatic cases of carotid artery stenosis were treated with CAS. The stent type included closed-cell stent and open-cell stent (48 closed-cell and 66 open-cell stents). Procedural, imaging, and clinical outcomes were retrospectively assessed and compared between the closed-cell stent group and the open-cell stent group.

Results: Periprocedural neurological complications were not significantly different between the two groups (p = 0.4). The presence of new ischemic lesions and number of new ischemic lesions on post procedural examination were not significantly different between the two groups (p = 0.32, p = 0.4).

Conclusion: Stent selection according to the morphological and clinical characteristics is thought to be important to reduce periprocedural ischemic complications.
