A patient presented with progressive ischemic stroke and received mechanical thrombectomy with a Solitaire FR device 29 days after stroke onset. The occluded V4 segment of the left vertebral artery showed a double rail sign on angiography, which indicated that the occlusion might have been caused by embolism instead of stenosis. The mechanical thrombectomy procedure was a 1-pass success and the patient was functionally independent with a modified Rankin Scale score of 1 at 3-month follow-up. The appearance of the vascular wall (double rail sign) of the occluded cerebral vascular segment on angiography may be a significant feature to identify the character of the occlusion even a long time after onset, which is important when planning further endovascular therapy in patients with ischemic stroke.
一位患者出现进行性缺血性脑卒中，并在发病 29 天后接受 Solitaire FR 装置机械取栓治疗。左侧椎动脉 V4 段闭塞，血管造影显示双轨征，提示闭塞可能由栓塞而非狭窄引起。机械取栓术 1 次即成功，患者在 3 个月随访时功能独立，改良 Rankin 量表评分为 1 分。闭塞脑血管段血管壁（双轨征）的血管造影表现可能是一个重要特征，即使在发病很长时间后，也可以识别闭塞的特征，这对于计划缺血性脑卒中患者的进一步血管内治疗非常重要。
