摘要：

目的 探讨64排螺旋CT血管成像(CTA)评估血液透析患者动静脉内瘘血管的临床价值。 方法 应用64排CTA对14例功能不全的内瘘血管及临床评估自体血管无条件造瘘的患者进行扫描、采象，应用最大密度投影、容积成象和曲面重建技术对图象数据进行处理和3维重建。 结果 根据64排CTA显示的结果，通过直视下手术、DSA介导及药物干预治疗，13例患者重建及修复了动静脉内瘘。结论 64排CTA能够成为临床评估内瘘血管的重要的形态学检测手段，并为下一步的临床治疗方案提供重要参考信息。

Abstract:

Objective To study the clinic value of 64-row spiral computed tomographic angiography (CTA) for the evaluation of arteriovenous vascular fistula in hemodialysis patients. Methods Fourteen patients with vascular fistula malfunction and without the potential to construct an autologous vascular fistula by clinical evaluation underwent 64-row spiral computed tomographic angiography. Images were processed, and 3-D images were reconstructed by applying maximum intensity projection, volume rendering, and surface reconstruction. Results Based on the 64-row CTA results, arteriovenous fistulas were reconstructed and repaired in 13 patients by surgery under direct view, DSA-mediated treatment or drug intervention. Conclusion 64-row CTA provides important images for evaluation of vascular fistula function and valuable information for clinical management of the fistula.
