Abstract:
Objective To investigate the distribution of in-stent recurrent stenosis (1RS) after balloon-angioplasty and stenting in elderly cerebral ischemic patient and its correlative factors.Methods Totally 158 elderly cerebral ischemic patients with extra-and/or intracranial artery stenosis were treated with 172 stents in our hospital.The inhibition of platelet function was assessed by using the thrombus elasticity chart system in perioperative period,and the anti-platelet agents were adjusted correspondingly.150 patients were followed up by digital subtraction angiography (DSA) and the other 8 patients were followed up by CT angiography,during an average follow-up duration of 8.3 months.Results There were 11 (6.4%) IRS lesions,among which 10 lesions were at the vertebral artery origin and 1 lesion was at common carotid artery bifurcation.23.8% of IRS happened after vertebral artery origin stenting,and all in-stent recurrent stenosis were in the origin of non-dominant vertebral artery,whose IRS rate was 66.7%.Conclusions IRS are more common found in vertebral artery origin than in other parts of vertebral artery and are more common found in nondominant side than in dominant side.
