椎动脉闭塞表现为无彩色血流显示。
方法回顾性分析超声诊断的11例椎动脉闭塞声像图特点。
Methods The ultrasonographic characteristics of vertebral artery occlusion in 11 patients diagnosed by ultrasound were analyzed retrospectively.
结论超声是诊断椎动脉闭塞首选和可靠的非介入性影像检查方法。
Conclusion Ultrasonography was the first and creditable noninvasive imaging method in diagnosis of vertebral artery occlusion.
结论血管内椎动脉闭塞治疗后循环不可夹闭动脉瘤是一种有效、安全的治疗方法。
Conclusion The vertebral artery occlusion with balloon or GDCs is an effective and safe method in treating posterior circulation intracranial unclipped aneurysms.
此外，MRA示除基底动脉和左侧椎动脉外，其它主要大血管均未见狭窄和闭塞；
In addition, MRA showed no stenosis or occlusion of large vessels except basilar artery.
目的：探讨枢椎横突孔结构在转头引起寰枢段椎动脉狭窄或闭塞的临床解剖学意义。
Objective: To study the clinical significance of axis transverse foramen in the etiology of the vertebral artery insufficiency after cervical rotational movement.
目的对椎动脉血管内闭塞治疗后循环不可夹闭动脉瘤疗效进行评价。
Objective To evaluate the therapeutic effect of vertebral artery occlusion for the posterior circulation unclipped aneurysms.
方法用血管内球囊或弹簧圈闭塞椎动脉治疗9例颅内后循环不可夹闭动脉瘤。
Methods 9 patients with posterior circulation intracranial unclipped aneurysms were treated with detachable balloons or GDCs to occlude proximal vertebral artery of aneurysms.
结果血管内闭塞近端椎动脉可使动脉瘤完全闭塞，神经受压和占位症状逐步改善、消失。3例经MRI追踪检查的病例显示动脉瘤明显缩小或完全消失。
Results The aneurysms were occluded and the space-occupying lesions disappeared in all the cases. 3 cases were followed up with MRI that showed aneurysms got smaller or disappeared.
