Venous thoracic outflow syndrome may occur as a result from compression of the subclavian and/or axillary vein and consequently, decreased blood flow and increased risk of thrombus formation. A previously healthy 34-year-old woman who, after intensive crossfit training, experienced sudden intense pain and swelling in her right upper arm was referred for computed tomography of her right upper arm and thoracic veins. The computed tomography was performed using bilateral injection of low dose, diluted contrast medium. The computed tomography venography revealed an elongated contrast medium embraced thrombus in the right subclavian and axillary vein. By using a dual injection consisting of diluted contrast medium, artifact-free visualization of arm veins and sufficient enhancement of thoracic veins can be achieved.
静脉性胸廓出口综合征可能由于锁骨下静脉和/或腋静脉受压而发生，进而导致血流减少和血栓形成风险增加。一名34岁的既往健康女性，在进行高强度的CrossFit训练后，右上臂突然出现剧烈疼痛和肿胀，遂被转诊进行右上臂及胸廓静脉的计算机断层扫描。计算机断层扫描采用双侧注射低剂量稀释造影剂的方式进行。计算机断层扫描静脉造影显示右锁骨下静脉和腋静脉内有一长形造影剂包绕的血栓。通过使用由稀释造影剂组成的双重注射法，可以实现手臂静脉无伪影的可视化以及胸廓静脉的充分强化。
