The off-label use of an extender wire during vertebral artery stenting and angioplasty with or with neuroprotection has not been previously reported.
Retrospective, single-patient, technical report.
After monorail balloon angioplasty was performed on a proximal left vertebral artery stenosis, the 190 cm long Accunet neuroprotection filter device was not long enough for delivery of an over-the-wire stent. After mating a 145 cm long, 0.014 inch extension wire to the filter device, a balloon-mounted Liberté stent was implanted with good angiographic and clinical results.
The off-label use of an extender wire permits successful over-the-wire stenting on a monorail neuroprotection device for vertebral artery endosurgery.
在椎动脉支架置入术和血管成形术中，使用或不使用神经保护装置的延长线超适应证使用尚未见报道。
回顾性、单病例、技术报告。
在对左侧椎动脉近端狭窄行单轨球囊血管成形术后，190cm 长的 Accunet 神经保护滤器装置不足以输送经导丝支架。将 145cm 长、0.014 英寸的延长线与滤器装置连接后，可在球囊上植入 Liberté 支架，血管造影和临床结果良好。
超适应证使用延长线可成功地在单轨神经保护装置上进行经导丝支架置入术，用于椎动脉血管内手术。
