Wingspan stenting can effectively prevent long-term strokes for patients with severe symptomatic atherosclerotic basilar stenosis
2016
ObjectiveTo investigate the safety and long-term effect of using the Wingspan stent for severe symptomatic atherosclerotic basilar artery stenosis (≥70%).Materials and methodsBetween July 2007 and April 2013, we had 91 consecutive patients (age range 41–82 years old) with symptomatic severe basilar stenosis (70–99%) who underwent Wingspan stenting at our center. All patients had stenosis-related temporary ischemic attack or strokes. We analyzed the demographic data, pre- and post-procedural cerebral angiography, technical success rate, peri-procedural complications, and clinical and imaging follow-ups.ResultsThe Wingspan stenting procedure was successful in all patients: The stenosis was reduced from 82.2% ± 5.8% pre-stenting to 15.9% ± 5.7% post-stenting. The 30-day peri-operative rate for stroke or death was 14.3%, which included ischemic stroke in 12 cases (12/91 = 13.2%) and subarachnoid hemorrhage in one case (1/91 = 1.1%), with a fatal or disabling stroke rate of 2.2%. Among the 77 patients with cli...
