摘要： 【摘要】目的 探讨多层CT静脉血管成像(multi-detector computed tomography venography，MDCTV)在中心静脉导管功能障碍评估中的应用价值。 方法 中心静脉导管动能障碍但胸片及颈内静脉超声无异常发现的患者31例，行MDCTV观察导管走形、中心静脉狭窄、血栓形成、纤维蛋白鞘形成等。 结果 MDCTV示导管位置异常10例，中心静脉狭窄5例，中心静脉血栓形成4例(2例伴有颈内静脉血栓形成)，管周纤维鞘形成7例，无明显异常者5例。 结论 MDCTV可有效评估中心静脉导管功能障碍，有临床推广价值。

Abstract: 【Abstract】Objective To evaluate the value of multi-detector computed tomography venography (MDCTV) in the assessment of tunneled hemodialysis central vein catheters (TCCs) dysfunction. 　Method A total of 31 patients who had TCCs dysfunction without abnormality found by X-ray and ultrasound were enrolled. MDCTV was conducted to observe the position of catheters and to detect central venous stenosis, thrombosis, and fibrin sheath formation. Proper intervention was given according to MDCTV results.　Results MDCTV found catheter malposition in 10 cases, central venous stenosis in 5 cases, central venous thrombosis in 4 cases, fibrin sheath formation in 7 cases, and negative in 5 cases. The blood flow on hemodialysis reached over 300ml/min after proper interventions given.  Conclusion MDCTV provided a valuable way to evaluate dysfunction of TCCs.
