64层螺旋CT与DSA评估冠状动脉支架置入术后的通畅性对比

目的:分析64层螺旋CT与DSA在评估冠状动脉支架置入术后通畅性及狭窄程度的价值。方法:选取2013年1月至2018年4月间我院收治的50例冠状动脉支架置入术治疗的急性冠状动脉综合征复查患者作为本研究对象；采用64层螺旋CT与DSA对急性冠状动脉综合征患者冠状动脉支架置入术后通畅性及狭窄程度进行评估，分析两者的评估价值。结果:采用64层螺旋CT及DSA检查手段对不同部位支架冠状动脉成像评分结果无明显差异P>0.05）；采用64层螺旋CT及DSA检查手段对不同直径支架冠状动脉成像评分结果无明显差异P>0.05）；采用64层螺旋CT及DSA检查手段对不同材料支架冠状动脉成像评分结果无明显差异P>0.05）；52例患者共置入96枚支架，患者均采用64层螺旋CT及DSA进行检查，结果显示64层螺旋CT及DSA检查差异无统计学意义P>0.05）。结论:对急性冠状动脉综合征患者冠状动脉支架置入术后通畅性及狭窄程度采用64排螺旋CT冠脉成像进行评估时与DSA评估结果高度一致。 

Comparison of 64-slice Spiral CT and DSA in Evaluation of Patency after Coronary Stenting

Objective: To analyze the value of 64 slice spiral CT and DSA in evaluating the degree of patency and stenosis after coronary artery stent implantation. Methods: 250 patients with acute coronary syndromes treated in our hospital from January 2013 to April 2018 were selected as the subjects of this group. 64 layers of spiral CT and DSA were used to evaluate the degree of patency and stenosis after coronary stent implantation in patients with acute coronary syndromes. The evaluation value of both was analyzed. Results: There was no significant difference in coronary artery imaging scores of different sites by 64 slice spiral CT and DSA (P>0.05). 64 layers of spiral CT and DSA were used for coronary artery imaging score of different diameter stents (P>0.05). 64 layers of spiral CT and DSA examination were used for different scaffolds. There was no significant difference in the results of the arteriography score (P>0.05); 96 stents were placed in 52 patients. The patients were examined with 64 spirals CT and DSA. The results showed that there was no statistical difference between 64 layers of spiral CT and DSA (P>0.05). Conclusions: 64 rows of spiral CT coronary angiography were used to evaluate the degree of patency and stenosis after coronary stent implantation in patients with acute coronary syndromes and the results were in high agreement with the results of DSA.
