64排螺旋CT血管成像在下肢动脉硬化诊断中的应用

目的探讨64排螺旋CT血管成像在下肢动脉硬化诊断中的价值。方法 28例怀疑下肢动脉硬化的患者行64排螺旋CT下肢血管成像（CTA）,其中4例进行了DSA检查。结果 CTA清晰显示28例患者的双下肢动脉血管及主要分支,其中26例患者可见大小、数目各异及分布不规则的斑块形成。共观察476段血管,其中0级302段,Ⅰ级54段,Ⅱ级50段,Ⅲ级42段,Ⅳ级28段。结论 64排螺旋CT下肢血管成像能够清晰显示动脉硬化的位置、斑块的性质和准确评价血管狭窄程度,是下肢动脉硬化较为理想的检查方法。

Application of 64 -slice Spiral CT Angiography in Diagnosis of Lower Extremity Arteriosclerosis

Objective To explore the value of 64-slice spiral CT angiography（CTA） in diagnosis of lower extremity arteriosclerosis.Methods The 64-slice spiral CTA of the lower extremity arteries were performed in 28 cases that suspected the lower extremity arteriosclerosis,4 patients underwent DSA.Results Of 28 cases,all lower extremity arteries and the main branches were displayed clearly,we could see different size,different number and irregular location plaque with 26 patients,degree 0 on the stenosis and occlusion 302 branches,degreeⅠ 54 branches,degree Ⅱ 50 branches,degree Ⅲ 42 branches and degree Ⅳ 28 branches in all 476 branches vessels.Conclusion 64-slice spiral CTA could diagnoze arteriosclerosis completely,which is an ideal method for the lower extremity arteriosclerosis.
