分析多层螺旋CT血管造影在动脉粥样硬化性肾动脉狭窄诊断中的价值

Value Analysis of Multi-slice Spiral CT Angiography in the Diagnosis of Atherosclerotic Renal Artery Stenosis

目的:探析多层螺旋CT血管造影在动脉粥样硬化性肾动脉狭窄诊断中的价值。方法:选取2016年8月~2018年4月期间收治的48例ARAS患者为研究对象,所有患者均给予MSCTA检查,以DSA检查结果为金标准,观察MSCTA肾动脉狭窄检查结果、总符合率。结果:肾动脉MSCTA与DSA检查证实两组结果评价肾动脉狭窄差异不具有统计学对比意义(P>0.05);以DSA结果为金标准,MSCTA对肾动脉狭窄0级、I级、II级、III级、IV级诊断总符合率分别为90.52%、90.52%、92.24%、96.56%、99.14%。结论:MSCTA可显示出ARAS的病变情况并作出安全、可靠的诊断,值得临床应用与推广。

Objective: To explore the value of multislice spiral CT angiography in the diagnosis of atherosclerotic renal artery stenosis. Methods: A total of 48 patients with ARAS in a hospital underwent surgery from August 2016 to April 2018 were enrolled. All patients were examined with MSCTA,taking DSA test results as the gold standard. The results of renal artery MSCTA examination, total coincidence rate were observed. Results: Renal artery MSCTA examination and DSA examination confirmed that there was no statistically significant difference in the evaluation of renal artery stenosis between the two groups ( P >0.05). Taking DSA results as the gold standard, the total coincidence rate of MSCTA in the diagnosis of grade 0, grade I, grade II, grade III and grade IV of renal artery stenosis was 90.52%, 90.52%, 92.24%, 96.56% and 99.14%, respectively. Conclusion: MSCTA can show the pathological changes of ARAS and provide safe and reliable diagnosis. It is worthy of clinical application and promotion.
