摘　　要：目的 探讨DSCT在冠状动脉支架术后随访中的应用价值.方法 对25例在我院行支架术后患者,于术后3 ～ 22月行DSCT检查,并与选择性冠状动脉造影（SCAG）对照,分析比较DSCT诊断支架再狭窄的敏感性、特异性及准确性.结果 在25例支架术后复查的患者中,发现支架总数57枚,DSCT诊断支架再狭窄率为49.12％ （28/57）,SCAG诊断支架再狭窄率为46.37％（27/57）,两者对支架再狭窄的诊断差异无统计学意义（P＞0.05）,DSCT诊断支架再狭窄的灵敏度、特异度、准确度为96.30％、93.33％、94.74％.与SCAG比较,DSCT误诊2例,漏诊1例.结论 DSCT可较准确地评估支架置入术后有无再狭窄,可成为冠心病患者支架置入术后的重要的随访手段.Objective To evaluate the application value of dual source computed tomography coronary angiography in the follow-up after coronary stenting. Methods 25 patients achieved DSCT coronary angiography and selective coronary angiography, and the duration from coronary stent implantation to scanning was 3 22 months. Analysis and comparison of stent restenosis by DSCT were performed to evaluate the diagnostic sensitivity, specificity and accuracy. Results The total number of 57 stents were found in 25 patients after stenting. DSCT diagno sticstent restenosis rate was 49.12 % （28/57）. SCAG diagnostic stentt restenosis rate was 46.37 % （27/57）. There existed no significant difference in the diagnosis of coronary artery stent restenosis between DSCT and SCAG, the sensitivity, specificity and accuracy of DSCT diagnostic stent restenosis were 96.30 %, 93.33 % and 94.74 % .Compared with SCAG,.DSCT misdiagnosed two cases and missed one case. Conclusion DSCT can accurately assess stents restenosis, and becomes an important means of follow-up in patients with coronary artery disease after stent.
