Abstract T P106: Stenting for Extracranial Vertebral Artery Stenosis: Results from China Interventional Stroke Registry
Objectives: Angioplasty and stenting are attractive options for treating ECVAS. We aimed to investigate the safety and long-term clinical outcomes of angioplasty and stenting in extracranial vertebral artery stenosis (ECVAS) in China.
Methods: Seven medical centers in China prospectively enrolled consecutive patients undergone angioplasty and stenting in ECVAS between Jan 2008 and Jan 2013. We collected patients’ clinical histories, symptoms, technical success and clinical outcomes of transient ischemic attack (TIA), stroke or death.
Results: Two hundred and twenty-four patients with 229 treated ECVAS were included. The technical success rate and periprocedural events rate were 95.2% (218/229) and 3.9% (9/229), respectively. With a median follow-up duration of 16 months, 201 patients with 205 treated ECVAS had long-term follow-up information, the composite events rate of TIA, stroke or death was 8.0% (18/224). History of TIA (hazard ratio [HR] 5.156, 95% confidence interval [CI]: 1.427-18.626), VA tandem lesions (HR 4.113, 95% CI: 1.112-15.212) and NIHSS≥4 at discharge (HR 4.854, 95% CI: 1.525-15.391) contributed independently to the composite events.
Conclusions: Angioplasty and stenting has high rate of technical success and low clinical events rates for ECVAS in China. Our study may lend support to perform angioplasty and/or stenting for ECVAS and help case selection for future randomized trials.
