The subclavian artery is an important structure that may be overlooked at CT of the chest and neck, in part because of its anatomic location at the periphery of the field of view but also because the clinical indication for CT examinations infrequently directs attention specifically to evaluation of the subclavian artery. As with all arteries, the subclavian artery has the potential to be involved in a variety of abnormalities, including pseudoaneurysms, dissections, stenosis or thrombosis, and vasculopathies. In addition, the subclavian artery can be secondarily involved as a collateral pathway because of an abnormality elsewhere. The subclavian artery may also be involved in surgical procedures to supply blood to other sites in the body or as an arterial access site. In these cases, recognizing the postsurgical appearance of the subclavian artery has become increasingly complex because of the use of the artery in an increasing number of procedures. Recognizing expected postoperative changes remains important to avoid mistaking them for abnormalities. The authors describe the imaging appearance of the normal anatomy of the subclavian artery and its anatomic variants, related abnormalities, and important postsurgical considerations. RSNA, 2022.
锁骨下动脉是一种重要的结构，在胸部和颈部 CT 中可能会被忽视，部分原因是其解剖位置在视野的外围，部分原因是 CT 检查的临床指征很少专门指向锁骨下动脉的评估。与所有动脉一样，锁骨下动脉有可能发生多种异常，包括假性动脉瘤、夹层、狭窄或血栓形成以及血管病变。此外，由于其他部位的异常，锁骨下动脉可能会作为侧支途径而受到牵连。锁骨下动脉也可能参与到为身体其他部位供血的手术过程中，或者作为动脉入路。在这些情况下，由于越来越多的手术中使用了动脉，识别锁骨下动脉的术后表现变得越来越复杂。识别预期的术后变化仍然很重要，以免将其误认为异常。作者描述了锁骨下动脉的正常解剖结构及其解剖变异、相关异常以及重要的术后注意事项。RSNA，2022 年。
