MSCTA在上肢动静脉瘘中的应用价值

目的:探讨MSCT在上肢动静脉瘘中的诊断价值。方法:回顾性分析9例经DSA及手术病理证实的上肢动静脉瘘患者的CTA资料。9例中,7例行DSA检查,6例经手术治疗。以DSA及手术检查结果为标准,分析CTA检查在上肢动静脉瘘诊断中的准确性。结果:所有患者血管重建图像显示良好。CTA可以很好地显示上肢动静脉瘘的供血动脉及引流静脉,明确病变的部位、范围以及受累的肌肉组织,与DSA检查及手术结果一致。结论:MSCTA是一种高度准确、非侵袭性的成像技术,在上肢动静脉瘘的诊断和治疗中有重要价值,可在很大程度上替代DSA检查。

Value of multi-slice spiral CT angiography in diagnosing arteriovenous fistula of the upper extremities

Objective： To study the role of multi-slice spiral CT angiography （MSCTA） in upper limb arteriovenous fistula. Methods： CTA data of 9 patients who underwent DSA and/or surgical treatment for upper limb arteriovenous fistula in Febru- ary 2006 to June 2012 were evaluated retrospectively. DSA examination were performed in 7 patients,and surgical treatment were performed in 6 cases. The CTA findings were analyzed and compared with DSA and surgery. Results： All cases were demonstrated successfully with CTA. CTA cc,,!d easily reveal feeding artery and draining vein of arteriovenous fistula, and con- firm the location, range and affected muscular tissue. The findings on CTA were consistent with DSA. Conclusion： MSCTA is a highly accurate and non-invasive examination technique in diagnosis and treatment of arteriovenous fistula of the upper ex- tremities, and can mostly replace DSA.
