| 摘 要： | 目的 利用氙气CT(Xe-CT)灌注技术分析脑供血动脉狭窄患者支架置人术前后的血流动力学特点,评价支架置人术的疗效及预后.方法 对19例脑供血动脉狭窄患者进行支架置人治疗,并利用Xe-CT进行血流定量评价,对比术前、术后低灌注区面积及脑血流量改善程度.结果 所有患者术前缺血区脑血流量(CBF)不同程度降低,术后血流量值显著改善;低灌注区域面积减小.结论 脑供血动脉狭窄时,脑组织存在易导致脑梗死的缺血区域,支架置人术可明显改善患者的血流动力学,其疗效可以通过Xe-CT灌注成像得到客观、准确的评价.

| Abstract: | Objective Hemodynamic characteristics of cerebral artery stenosis and curative effect of stent placement using Xenon-CT.Methods 19 patients with cerebral artery stenosis were examined and evaluated by Xe-CT before and after the stent placement.Measurement and comparison of the changes were taken before and after the therapy.Results Preoperative Xe-CT revealed different decrease of CBF in the ipsilateral cortex.Ischemic areas reduced significantly after the stenting placement.Conclusion Xe-CT is beneficial f... |
