摘要
目的利用双源CT冠状动脉成像(DSCTA)探讨糖尿病(DM)患者冠状动脉支架再狭窄(ISR)及非支架血管狭窄情况。方法随访因冠心病入院并成功接受冠状动脉支架置入的109例患者,按照有无糖尿病分组,其中糖尿病组(DM)42例及非糖尿病组(NDM)67例,对患者的一般资料(年龄、性别、吸烟史、高血压、高血脂、冠心病家族史)及冠状动脉支架、非支架血管情况进行分析。结果随访6～36个月后,两组患者的一般资料无统计学差异,但DM组支架再狭窄发生率高,多发生在支架两端,且以非钙化斑块为主;非支架血管病变广泛,钙化严重。结论双源CT能清晰显示糖尿病患者支架及非支架血管的狭窄,明确狭窄部位及引起狭窄病变性质,可作为糖尿病患者支架术后随访的一种手段。
Objective By use of dual-source CT coronary angiography （DSCTA） to investigate patients with diabetes mellitus （DM） in patients with coronary stent restenosis （ISR） and non-stent vascular stenosis. Methods We followed up 109 pationts with coronary heart disease admitted to hospital and underwent successful coronary stent implantation, grouped in accordance with the absence of diabetes mellitus, including diabetic group （DM）, 42 cases and non-diabetic group （the NDM） of 67 cases, analysed the general patient information （age, sex, smoking history, hypertension, high cholesterol, family history of CAD） and coronary stents, non-stent vascular situation. Results When followed up for 6 36 months, no significant difference was feund between two groups of patients with general information. In DM group stent restenosis had high incidence occurred in the stent at both ends, and mainly presented with non-calcified plaque; There were wide range of non-stent vascular lesions, severe calcification. Conclusion Dual-source CT can clearly show the diabetic patients with stents and non-stent vascular stenosis, which can take a means as follow-up after stent diabetic pa- tients.
