Abstract:
Objective: To investigate the perioperative complications of balloon expandable stent and self-expanding stent (Wingspan stent) in the treatment of patients with symptomatic basilar artery stenosis. Methods: Sixty-two patients with symptomatic basilar artery stenosis admitted to the Department of Neurosurgery, the First Affiliated Hospital of Harbin Medical University from November 2006 to June 2011 were analyzed retrospectively. Twenty-four of them were treated with the balloon expandable stent and 38 were treated with the self-expanding stent. The residual stenosis rate and perioperative complications in patients of both groups were observed. Results: Circled digit oneEndovascular stenting was performed successfully in all the 62 patients. Among them, the stenotic rate from 83 ± 8% decreased to 10 ± 5% immediately after procedure in the balloon expandable stent group. The stenotic rate from 81 ± 11% decreased to 17 ± 10% immediately after procedure in the self-expanding stent group. Circled digit twoSeven (29.2%) of the 24 patients had perioperative complications in the balloon expandable stent group and 4 (10.5%) in the self-expanding stent group. The difference was not statistically significant (P = 0.061). However, if excluding the surgical factors, only comparing the stent-related ischemic complications, it showed that the incidence of complications (2/38, 5.3%) in the self-expanding stent group was significantly lower than that (7/24, 29.2%) in the balloon expandable stent group. The difference was statistically significant (P = 0.022). Observing from the pathological standpoint, it showed that the patients of Mori C type has higher incidence of complications. Conclusion: Compared to the balloon expandable stent, the self-expanding stent has a lower incidence of perioperative complications in the treatment of symptomatic basilar arterial stenosis, but the postoperative residual stenosis of the self-expanding stent is higher.
