CT动脉造影诊断冠状动脉支架内部再狭窄的意义及临床护理

目的探讨双源Flash CT动脉造影诊断冠状动脉支架内部再狭窄的价值及护理体会。方法选取62例(108枚支架)疑似支架内部再狭窄患者为观察对象,依次给予双源Flash CT动脉造影检查和DSA检查,以DSA检查为金标准,分析CT动脉造影检查的诊断效能。同时根据患者检查期间护理措施的不同将62例患者分为对照组和研究组,每组各31例。其中对照组患者在检查期间实施常规护理措施,研究组在对照组基础上加强护理干预,比较两组护理效果。结果双源Flash CT动脉造影检查阳性检出率13.89%、阴性86.11%;DSA检查阳性检出率11.11%、阴性88.89%,二者对比无明显差异(P> 0.05)。以常规冠状动脉造影检查为金标准,双源Flash CT动脉造影检查在支架内再狭窄诊断中的特异性为95.83%、敏感性为91.67%、阳性预测值73.33%、阴性预测值98.92%、准确性95.37%。对比检查期间不同护理方式实施效果发现,研究组检查前汉密顿焦虑量表(HAMA)和汉密顿抑郁量表(HAMD)评分与对照组相比无明显差异(P> 0.05);两组检查后HAMA评分和HAMD评分均低于本组...

Significance of CT angiography in the diagnosis of coronary stent restenosis and clinical nursing

Objective To explore the value of Dual-source Flash CT angiography in diagnosing restenosis inside coronary stents and nursing experience.Methods Sixty-two patients(108 stents)with suspected internal restenosis of the stent were selected as the research objects.Dual-source Flash CT angiography and conventional coronary angiography were given sequentially.With conventional coronary angiography as the gold standard,Dual-source Flash CT angiography was analyzed.At the same time,62 patients were divided into a control group and a study group according to the different nursing measures during the examination period,with 31 cases in each group.Among them,patients in the control group implemented routine nursing measures during the examination,and the study group strengthened nursing intervention on the basis of the control group to compare the nursing effects of the two groups.Results The positive detection rate of Dual-source Flash CT angiography was 13.89%and the negative 86.11%;the positive detection rate of gold standard examination was 11.11%and the negative 88.89%.There was no significant difference between the two(P>0.05).With conventional coronary angiography as the gold standard,the specificity of Dual-source Flash CT angiography in the diagnosis of in-stent restenosis is 95.83%,sensitivity was 91.67%,positive predictive value was 73.33%,negative predictive value was 98.92%,and accuracy was 95.37%.Comparing the implementation effects of different nursing methods during the inspection period,it was found that the hamilton anxiety scale(HAMA)and hamilton depression scale(HAMD)scores of the study group before the inspection were not significantly different from those of the control group(P>0.05);After the examination,the HAMA score and HAMD score were lower than the pre-examination score of this group(P<0.05);the HAMA score and HAMD score of the study group after the examination were lower than the control group(P<0.05).Conclusion Dual-source Flash CT angiography has high specificity,sensitivity and accuracy in diagnosing restenosis inside coronary stents.However,it is necessary to supplement the corresponding nursing interventions during the examination to ensure the smooth progress of the examination.
