肾动脉狭窄多层螺旋CT血管成像与DSA对照研究

目的:探讨多层螺旋CT血管成像(MSCTA)在肾动脉狭窄性病变中的应用价值。方法:对36例临床疑有肾血管性高血压患者行16层或64层螺旋CT血管成像,并行三维血管重建,经MSCTA发现肾血管及其周围血管病变者共28例,再做DSA对照检查。结果:36例中MSCTA诊断肾动脉狭窄19例,其中2例为双侧肾动脉狭窄,2例为肾动脉变异畸形。3例肾上腺瘤,2例肾上腺增生,1例为多囊肾。而28例经DSA检查病例中,21例有不同程度肾动脉狭窄,MSCTA诊断与DSA比较符合率达90%以上。结论:MSCTA对肾动脉狭窄诊断有很好的临床应用价值。

Multi-Slice Spiral CT Angiography in Renal Areterial Stenosis:Comparision with DSA

Objective To study the clinical application of Multi-slice spiral CT angiography (MSCTA) in renal arterial stenosis. Methods 36 patients clinically suspected of renovascular hypertension were examined by 16 slice or 64 slice spiral CT angiography. After scanning , three dimensional reconstruction of the blood vessels were operated. 28 cases were detected diseases of renal vessels and perivascular, and then compared with DSA. Results In the 36 cases, MSCTA showed 19 renal areterial stenosis, 3 adrenal gland neoplasms, 2 adrenal hyperplasia, 1 polycystic kidney disease. In 19 cases with MSCTA , there were 2 double renal areterial stenosis and 2 renal areterial anatomical variants. DSA showed 21 renal areterial stenosis with various degree, the accordant rate of MSCTA and DSA exceeded 90%. Conclusion MSCTA play an important role in clinical application in diagnosis of renal arterial stenosis.
