摘要
目的:研究64排螺旋CT冠状动脉成像评价冠状动脉支架通畅性的价值。方法:对70例冠状动脉支架植入术后9～12个月患者行64排螺旋CT冠脉成像(共106个支架),观察支架及其支架血管的通畅性。采用5分制计分法评价支架的轴位多平面重建图像,同时测量支架内管腔直径。计算支架内管腔直径与支架近端的管腔直径比值。结果:图像平均质量达到优良水平。支架通畅85个(80.2%),支架内狭窄3个,闭塞1个,支架前后血管狭窄18个。平均支架内腔直径比率为(78.3±12.6)%。结论:64排螺旋CT可作为冠状动脉支架置入术后随访观察和了解冠心病进展情况的重要手段。
Objective： To evaluate the clinical value of assessment of coronary stent patency by 64 slice spiral CT in patients after coronary stent implanting. Methods： Totally 70 patients （106 stents） were investigated by 64 slice spiral CT. The image quality of stents were evaluated by a five scores scale and coronary lumen diameter. Stent lumen diameter was compared with the vessel diameter proximal of the stents to assess their stent lumen stenosis. Conventional coronary angiography was performed in 70 patients, and 106 stents were evaluated. Results： The image quality was good to excellent. The stent was easy and smooth in 85 cases （80.2%, 85/106）. The average lumen diameter of stent was （78.3± 12.6）%. Conclusion： The 64 slice spiral CT is a useful tool to assess the coronary stent patency.
