摘要
目的 评价与分析冠脉CTA在经皮冠状动脉介入治疗（PCI）术后随访中的应用价值.方法 回顾性选取2010年1月至2013年10月煤炭总医院完成首次PCI术患者68例,共植入支架145枚.入选患者在术后1年内未再行任何血管再通术（球囊扩张、支架、搭桥等）,术后1年左右来我院复查.患者复查时均无明显胸部不适主诉.复查时接受冠脉CTA和冠状动脉造影（CAG）两种检查（二者间隔不超过3个月）,分别记录各自分析的支架数目、直径、长度、厚度等,对比两种检查方法诊断支架再狭窄（ISR）的灵敏度、特异度及准确性等.结果 145枚支架中10枚支架因CTA图像差不能评估而排除.135枚可评估支架中,11枚（8.1％）支架经CAG诊断为ISR,其中10枚（7.4％）支架CTA正确诊断ISR,1例漏诊;CTA误诊9例（其中8例支架直径≤2.75 mm,6例支架长度≥30 mm）.结论 无明显心绞痛症状的PCI患者术后1年复查,冠脉CTA可作为首选的检查,CTA对支架内再狭窄的定性诊断高于定量诊断.
Objective To evaluate the value and insufficient of coronary CTA in the follow-up of PCI patients. Methods A total of 68 patients and 145 stents after PCI who underwent coronary CTA and CAG in our hospital were analyzed. All of them come from January 2010 to October 2013 of our hospital. Patients have no obvious chest complaints and in 1 years after operation no longer any revascularization（PTCA, PCI and CABG）. The sensitivity, speeifity, the positive and negative predictive were evaluated. Results 10 stents cannot be evaluated and exclusion and in the other 135 stents which can be evaluated 11 cases （8.1%） were diagnosed ISR by CAG. 10 of them （7.4%） CTA diagnostic accuracy of ISR, 1 cases of missed diagnosis, 9 cases of misdiagnosis of CTA （including 8 cases of stent diametedess than or equal to 2.75 ram, 6 cases of stent length greater than or equal to 30 mm ）. Conclusion CTA is very helpful for the diagnosis of ISR and it can be used reviewing of 1 years of PCI for patients with no obvious symptoms of angina. The qualitative diagnosis for ISR of CTA is better than quantitative diagnosis.
