DSA三维重建成像在颈动脉狭窄诊断及内支架成形术中的初步应用
Preliminary cvaluation of 3-D angiography in diagnosis of carotid stenosis and carotid stenting
【摘要】 目的 总结血管造影三维重建成像 (3D Angio)在颈动脉狭窄诊断及支架成形术中的应用。方法 2 3例经常规血管造影证实有颈动脉狭窄患者 ,行 3D Angio检查并对其结果进行对比分析。其中 1 6例患者分别在行支架成形术前后作常规血管造影 (2D Angio)和 3D Angio检查 ,分析其治疗前后血管的改善情况。结果 3D Angio可以从不同角度观察血管狭窄段的轮廓改变 ,准确地判断狭窄程度和范围 ;还可了解管腔内情况 ,显示管腔变小 ,凸凹不平和突向腔内的斑块。内支架成形术后 ,管腔轮廓恢复正常 ,腔内凸凹不平可变光整 ,突向腔内的斑块消失。结论 3D Angio对诊断颈动脉狭窄程度、了解狭窄段管腔内改变、评价支架成形术的结果可提供帮助
【Abstract】 Objective To summarize the initial application of three dimensional angiography(3D angio) in the diagnosis of carotid stenosis and carotid stenting.Methods 23 patients with carotid stenosis confirmed by conventional angiography (two dimensional angiography, 2D Angio) received 3D Angio including 16 accepted both 2D Angio and 3D Angio before and after carotid stenting and then undengone comparative study. Results 32 stenosed lesions were found, including 5 in common carotid artery, 19 in neck section of internal carotid artery, 3 in patrous section, 2 in caverous sinus and 3 in middle cerebral artery. 3D Angio could demonstrate the changes of stenosed segment from every point of view. The degree and extent of stenosis could be accuratly evaluated. The characterization of lesions including the diminution of lumen and coarse plaques could be clearly displayed. After stenting, the wall of stenosed segment became smooth and the plaques disappeared.Conclusions The diagnosis and treatment of carotid stenosis by 3D Angio is helpful to accurately estimate the extent of stenosis, the characterization of the lesions and monitor the results of stenting.
