目的探讨64排螺旋CT在肾动脉狭窄(RAS)诊断中的价值。方法对50例继发性高血压患者行肾动脉CT血管造影(CTA)检查,同时对其中40例行数字减影血管造影(DSA)检查,观察肾动脉CTA的检查效果。结果 CTA诊断肾动脉轻度、中度、重度狭窄和闭塞的灵敏度和特异性分别为88.80%和89.40%、91.30%和92.40%、94.10%和96.30%、100.00%和100.00%。结论在诊断肾动脉狭窄方面,64排肾动脉CTA能满足临床需求。
Objective To investigate the value of 64-slice spiral CT in the diagnosis of renal artery stenosis (RAS). Methods Renal artery CT angiography (CTA) was performed in 50 patients with secondary hypertension. At the same time, 40 patients underwent digital subtraction angiography (DSA) to observe the effect of renal artery CTA. Results The sensitivity and specificity of CTA for the diagnosis of mild, moderate, severe stenosis and occlusion of renal artery were 88.80% and 89.40%, 91.30% and 92.40%, 94.10% and 96.30%, 100.00% and 100.00%, respectively. Conclusion In the diagnosis of renal artery stenosis, 64 rows of renal artery CTA can meet the clinical needs.
