目的:分析血管内介入治疗对急性颅内前循环大血管闭塞的临床疗效.方法:抽取2020年10月至2022年10月我院收治的急性颅内前循环大血管闭塞患者共30例,实施回顾性分析,均采取血管内介入治疗,分别记录、分析患者术后30天、90天、180天的美国国立卫生研究院卒中量表(NIHSS)评分、改良Rankin评分量表(MRS)评分、良好预后率及全因死亡率.结果:30名患者术后30天、90天及180天NIHSS评分、MRS评分明显降低,良好预后率明显提升,全因死亡率明显减低.结论:血管内介入治疗安全有效,如果严格把

海绵状血管瘤是在出生时即出现的低血流量的血管畸形,又称为静脉畸形.该病不仅存在美容问题,还会导致邻近器官等功能障碍,甚至因外伤或继发感染引发严重出血.磁共振(magnetic resonance,MR)具有多序列、多方向成像特点,在海绵状血管瘤诊断,特别是治疗效果的评价方面具有一定优势.

Objective To evaluate the diagnostic value of 64-detector helical CT angiography for follow-up the artery of lower extremity after artificial vascular graft.Methods 68 cases with artificial vascular graft of artery of lower extremity underwent 64-detector helical CTA from 2004-06 to 2006-05.The data were transmitted to ADW4.2 workstation and reconstructed by maximum intensity projection(MIP),volume rendering(VR) and curved planar reconstruction(CPR),then generally analyzed with original axial images.Results In 68 cases,87 grafts were showed by 64-detector helical CTA including the location and shape of artificial vascular graft,the narrowing degree of vascular lumen,collateral circulation and complication.Conclusion 64-detector helical CTA is reliable and accurate in evaluating the artificial vascular graft,and can be used as the first modality in evaluating the artery of lower extremity after artificial vascular graft at present.

目的:评估多层螺旋CT血管造影在脑血管疾病诊治中的价值.方法:对20例脑血管病患者进行CT血管造影检查,应用后处理工作站进行脑血管三维重建,显示病变解剖关系.结果:全部20例病变其中动脉瘤10例,动静脉畸形8例,脑血管狭窄2例均经手术及DSA证实.其中一例动脉瘤手术证实,DSA未检出.结论:CT血管造影三维重建可全方位显示脑血管,具有微创、安全、可靠、费用低廉等特点,适合于手术计划制定、术前定位及随访.
