【摘要】 目的:探讨C臂CT技术在颅内支架置入术后支架复查显影方面的应用价值。方法:2017年8月至2018年5月收治我科支架复查患者27例,均通过C臂CT技术复查,所有颅内支架置入术后的患者,肘部静脉注入对比剂,通过三维旋转采集后,经3D类CT软件后处理,运用飞利浦支架显影技术和MIP技术,观察支架网眼、支架mark、支架与靶血管的关系。结果:C臂CT技术能清晰显示颅内支架结构及其与血管壁的关系(支架贴壁情况、支架开通程度、有无支架内再狭窄)结论:C臂CT技术可以很好的显示颅内支架形态和血管壁间的关系。在颅内支架复查中,具有创伤小、风险小、经济费用低、无需入院等优势,对支架置入术后患者的随访,有较高的临床应用价值。更多还原

【Abstract】 Purpose: To study the application value of C-arm CT technology in the evaluation of stent condition after intracranial stent implantation. Methods: From August 2017 to May 2018, 27 patients underwent stent therapy in our hospital, all of whom were followed-up by C-arm CT technique. All patients were injected with contrast agent in the elbow vein after intracranial stenting, and images were collected through three-dimensional rotation method.The stent mesh, stent mark and the relationship between stent and target vessel were evaluated by using Philips stent visualization technique and MIP with 3 D CT software. Results: The intracranial stent structure and its relationship with the blood vessel wall could be clearly shown by C-Arm CT(Dyna CT) technique(circumstances of stent attachment, degree of stent opening, in-stent restenosis). Conclusion: The relationship between intracranial stent morphology and vessel wall can be well shown by C-Arm CT(Dyna CT). In the followed-up of intracranial stents, it has the advantages of low risk, low economic cost, and no need for admission, which also suggests high clinical value for the follow-up of patients after stent implantation.更多还原
