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 value of 64-slice spiral CT in diagnosis of renal artery stenosis (RAS).Methods Renal artery CT angiography (CTA) was applied for examination of 50 patients with secondary hypertension. Digital subtraction angiography (DSA) was applied for examination of 40 cases among them. Examination results of renal artery CTA were observed.Results Sensitivity and Specificity of CTA in diagnosis of mild, moderate, and severe stenosis were respectively 88.80% and 89.40%, 91.30% and 92.40%. 94.10% and 96.30%, 100.00% and 100.00%.Conclusion 64-slice renal artery CTA can meet the clinical requirement in diagnosis of renal artery stenosis.
