A 45-year-old female dialysis patient with sudden onset of severe pain in the left shoulder and chest was referred for computed tomography of her left arm and thoracic veins. The computed tomography venography revealed 2 completely occluded venous grafts and 2 pronounced stenoses of the subclavian vein. By using a dual injection of diluted and undiluted contrast medium, artifact-free visualization of arteriovenous fistula, arm veins and adequate enhancement of thoracic veins were obtained.
一名45岁的女性透析患者，突然出现左肩部和胸部剧痛，被转诊进行左臂和胸静脉的计算机断层扫描。计算机断层扫描静脉造影显示2条静脉移植物完全闭塞，锁骨下静脉有2处明显狭窄。通过使用稀释和未稀释造影剂的双重注射，获得了动静脉瘘、手臂静脉的无伪影可视化以及胸静脉的充分强化。
