多层CT与DSA对急性冠状动脉综合征患者冠状动脉支架置入术后通畅性及狭窄程度的影响

研究多层CT与DSA对急性冠状动脉综合征患者冠状动脉支架置入术后通畅性及狭窄程度的影响。以我院2017年8月-2018年11月在我院诊断治疗的急性冠脉综合征患者80例作为研究对象,对所有患者进行经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)手术后,分别进行DSA检查以及64排螺旋CT检查。分析不同检查的冠状动脉狭窄、通畅性之间的差异以及不同检查的一致性。通过对CT检查结果以及DSA检查结果的配对卡方检验,两组患者的检查结果之间的差异不存在统计学意义,两种检查对患者的冠状动脉的狭窄情况诊断一致性较好;两种检查方法对患者的管壁厚度以及管径直径诊断之间的差异不存在统计学意义,两种检验方法对患者的管壁厚度以及管径直径诊断一致性较好。总之,多层CT与DSA对急性冠状动脉综合征患者冠状动脉支架置入术后通畅性及狭窄程度的诊断具有较高的一致性,建议临床推广。

The Influence of Multi-slice CT and DSA on Patency and Stenosis Degree of Coronary Artery Stent Implantation in Patients with Acute Coronary Syndrome

Abject To study the effects of multi-slice CT and DSA on patency and stenosis degree of patients with acute coronary syndrome after coronary artery stent implantation.Eighty patients with acute coronary syndrome diagnosed and treated in our hospital from August 2017 to November 2018 were selected as the study subjects.After percutaneous coronary intervention(PCI)operation,DSA and 64-slice spiral CT were performed in all patients.The differences of coronary stenosis and patency between different examinations and the consistency of different examinations were analyzed.Through paired chi-square test of CT results and DSA results,there was no significant difference between the two groups.The two methods had good consistency in diagnosis of coronary artery stenosis.There was no difference in diagnosis of wall thickness and diameter between the two methods.In statistical significance,the two methods have good consistency in the diagnosis of wall thickness and diameter of patients.In conclusion,multi-slice CT and DSA have a high consistency in the diagnosis of patency and stenosis degree after coronary artery stent implantation in patients with acute coronary syndrome.It is suggested that they be popularized in clinic.
