目的探讨旋转三维重建数字减影血管成像(3D DSA)在主动脉夹层腔内隔绝术中的应用价值。方法 2006年1月至2010年5月,25例胸主动脉夹层患者接受腔内隔绝术治疗,其中5例患者CTA以及常规DSA均不能显示破口位置,我们对其采用了3D DSA检查。结果通过3D DSA清楚显示破口,成功实施支架置入术。结论 3D DSA能多方位观察破口与周围血管关系,提供准确显示病变的参考角度,是主动脉夹层腔内隔绝术中常规手段的重要补充。
Objective To investigate the value of rotational 3D reconstruction digital subtraction angiography (3D DSA) in endovascular exclusion of aortic dissection. Methods From January 2006 to May 2010, 25 patients with thoracic aortic dissection were treated by endovascular graft exclusion. Among them, CTA and conventional DSA were not found in 5 patients. We used 3D DSA for them. The results were clearly demonstrated by 3D DSA and successful stent placement. Conclusion The 3D DSA can observe the relationship between the breach and the surrounding blood vessels in various directions and provide a reference point for accurately displaying the lesion. It is an important supplement to conventional means of endovascular exclusion of aortic dissection.
