摘要
目的 评价三维数字减影血管造影 (3DDSA)在颈动脉狭窄血管内治疗中的价值。方法 对 13 8例缺血性脑血管病颈动脉的 3DDSA与二维 (2D)DSA图像进行比较 ,分析颈动脉的形状、狭窄的显示、血管内治疗的必要性、血管内治疗的工作角度及支架的选择。结果 与 2DDSA相比 ,3DDSA能更清晰显示颈动脉狭窄的形状及程度 ,能提供最佳血管内治疗的工作角度 ,使用 3DDSA能正确决策支架的选择。结论 3DDSA在颈动脉狭窄血管内治疗中具有重要的价值 ,能提供许多 2DDSA不能提供的有价值信息 。
Objective To evaluate three dimensional digital subtraction angiography (3D DSA) in endovascular treatment of carotid stenosis. Methods In 138 patient with ischemic stroke, the shape and stenosis of carotid artery, the feasibility of endovascular treatment and the choice of the stent were analyzed by 2D DSA and 3D DSA. Results Comparing with 2D DSA,3D DSA could clearly depict the carotid artery in shape and stenosis with correct figuring of the feasibility for endovascular treatment and choice of the stent. Conclusions 3D DSA shows the major importance in endovascular treatment of carotid stenosis providing more valuable informations than 2D DSA.
