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。
Objective To investigate the value of 64-slice spiral CT angiography in the diagnosis of lower extremity arteriosclerosis. Methods Twenty-eight patients with lower extremity arteriosclerosis underwent 64-slice spiral CT (lower extremity arterial angiography) and 4 of them underwent DSA. Results CTA clearly showed the arterial vessels and major branches of both lower extremities in 28 patients. Among them, 26 patients were found with different size, number and distribution of irregular plaques. A total of 476 vessels were observed, of which 302 were in grade 0, 54 in grade Ⅰ, 50 in grade Ⅱ, 42 in grade Ⅲ and 28 in grade Ⅳ. Conclusion 64-slice spiral CT lower extremity vascular imaging can clearly show the location of atherosclerosis, the nature of plaque and the accurate assessment of the degree of vascular stenosis, lower extremity arteriosclerosis is an ideal test method.
