Abstract:
Objective To evaluate the curative effect,safety,and medium-term effect of intracranial artery stenosis stent (ICASS) for the treatment of the symptomatic intracranial artery stenosis.Methods ICASS was performed in 21 cases with the symptomatic intracranial artery stenosis.The stenting success rate,the improvement rate of stenosis post-stenting and the incidence of complications were observed.The change of the scores of the Modified Rankin Scale (MRS)and National Institutes of Health Stroke Scale (NIHSS)between pre-and post-stenting (1 month,3 months,6 months,12 months and 2 years)and the occurrence of ischemic cerebrovascular events after stenting were compared and analyzed respectively.Results Except one case failed because of intracranial hemorrhage during the operation,other 20 patients were treated with endovascular stent plasty successfully,the total technical achievement ratio was 95.2%.The aver-age stenosis ratio decreased from (73.4±7.9)% to (13.7±9.2)%.The complications incidence was 4.8% within the peroperative. 9 patients were reviewed with DSA in 6 months,the average ratio of stenosis was (29.5 ±12.2)%,no patient was found with the restenosis.Compared with pre-stenting,the score of MRS and NIHSS at the follow-up duration of 3 months,6 months,12 months and 2 years post-stenting of patients were significant improved (all P < 0.05 ).During the follow-up period,2 patients were found with new transient ischemia attack (TIA),1 patient had non-targeted vascular CI without other target vascular therapy-related com-plications.Univariate analysis indicated that patients with elderly (≥ 75 years old),or hypertension,or diabetes,or dyslipidemia,or in the set of events to endovascular treatment for longer than 1 month,or with more than two independent risk factors for patients with underlying diseases treatment,or without systemic therapy,whom would be much more easily to reoccur the cerebrovascular events in post-operation(all P <0.05 ).Conclusion ICASS should be an effective and safe therapeutic method to the symptomatic intracra-nial arterial stenosis.The medium-term efficacy is significant.Serious complications might still be emerge with endovascular stent plasty,so close attention must be paid with.
