Abstract
PURPOSE: To investigate the safety, effect and instent restenosis rate of Wingspan stenting in treating patients with intracranial vertebral artery atherosclerotic stenosis (70-99%) concurrent with contralateral vertebral artery atherosclerotic diseases. MATERIALS AND METHODS: Eighty-eight patients with severe symptomatic intracranial vertebral artery atherosclerotic stenosis (≥70%) combined with contralateral vertebral artery atherosclerotic diseases were treated with the Wingpsan stent. All the baseline, cerebral angiography, success rate, perioperative complications, clinical and imaging follow-up data were prospectively analyzed. RESULTS: The success rate of stenting was 100%, and the mean stenotic rate was reduced from prestenting (84.9±6.8)% to poststenting (17.2±5.9)%. The perioperative stroke rate was 1.1%. Among eighty patients (90.9%) with clinical follow-up 8-62 months (mean 29.3±17.2) poststenting, five (6.3%) had posterior circulation TIA only, three (3.8%) had mild stroke in the posterior circulation but recovered completely, and another five patients greater than 70 years old died of non-ischemic stroke. Imaging follow-up in 46 patients (52.3%) 5-54 months (mean 9.9±9.9) following stenting revealed instent restenosis in 12 patients (26.1%) including 7 (58.3%) symptomatic restenosis. Age and residual stenosis were the two factors to significantly (P<0.05) affect instent restenosis. CONCLUSION: Wingspan stenting in the intracranial vertebral artery atherosclerotic stenosis combined with contralateral vertebral artery atherosclerotic diseases has a low perioperative stroke rate and a good preventive effect on long-term ischemic stroke, but the instent restenosis rate is a little high.
