代谢综合征患者肾动脉狭窄的SCTA与DSA对比研究

目的探讨代谢综合征(MS)患者中肾动脉狭窄的发生率及无创性筛检的必要性与可靠性。方法45例MS患者预行肾动脉螺旋CT血管造影(SCTA),对所检出的14例肾动脉狭窄者行肾动脉数字减影血管造影(DSA)对照,并对SCTA及DSA结果进行对比分析。结果45例MS患者中SCTA显示肾动脉正常31例,其余14例患者存在单侧或双侧肾动脉狭窄,DSA对照显示肾动脉正常6条,肾动脉狭窄22条,与SCTA显示的情况基本符合。结论MS患者中肾动脉狭窄的发生率约31.1%,对可疑患者应常规予以肾动脉SCTA检查。

Evaluation of renal artery stenosis in patients with metabolic syndrome by spiral CT angiography and digital subtraction angiography

Objective To investigate the occurrence rate of renal artery stenosis in patients with metabolic syndrome(MS) and evaluate the reliability and necessity of non-invasive examination for MS patients.Methods Forty-five MS patients were examined the renal artery with spiral CT angiography(SCTA),14 patients with renal artery stenosis were performed digital subtraction angiography(DSA).The results of SCTA and DSA were compared.Results In 45 MS patients,SCTA showed 31 patients with normal renal artery,and 14 patients with single side or double sides renal artery stenosis.DSA showed 6 normal renal arteries and 22 renal artery stenosis,the result accorded with SCTA.Conclusion The occurrence rate of renal artery stenosis was 31.3% in MS patients.It is necessary to perform SCTA examination in suspicious patients.
