螺旋CT血管造影及三维重建在主动脉夹层诊断中的应用

Application of spiral CT angiography and three dimensional reconstruction in the diagnosis of aortic dissection

目的:评价螺旋CT血管造影(SCTA)及三维重建在主动脉夹层诊断中的临床应用。方法:对21例主动脉夹层患者进行了SCTA成像及三维重建,并与手术及血管造影对照。结果:SCTA能清楚显示主动脉夹层病变及其复杂的解剖关系,如双腔、内膜片及累及的范围等。与血管造影及手术对照,SCTA的诊断符合率达100％。结论:SCTA二维与三维重建的联合应用,有助于主动脉夹层的诊断并可指导手术,且有望取代传统血管造影。

Objective: To evaluate the clinical application of spiral CT angiography (SCTA) and three dimensional (3D) reconstruction in the diagnosis of aortic dissection. Methods: 21eases of aortic dissection underwent SCTA and 3D reconstruction,and all cases were confirmed by operation or angiography. Results: SCTA images could clearly show the lesions of aortic dissection and its complicated anatomic relationship. The aortic double lumen, the intimal flap and the affected area was showed on all cases. The SCTA diagnosis coincided will with the operative findings in 100%. Conclusion: Combined application of two and three dimensional reconstruction of SCTA is helpful in correct diagnosis and guiding operation and may replace conventional angiography in aortic dissection in future.
