Abstract：
BACKGROUND: The aberrant origin of the right subclavian artery (ARSA), also known as the lusoria artery, is a congenital malformation with an incidence of 0.5-4.4%. Most cases are incidental due to minimal clinical manifestations. Computer tomography (CT) is important in diagnosing and evaluating these patients.
METHODS: We conduct a computerized search in two databases, PubMed and EMBASE, for articles published between 1 January 2022 and 31 December 2023, PROSPERO code: CRD42024511791. Eligible for inclusion were case reports and case series that presented the aberrant origin of the right subclavian artery. The main outcome was the highlighting of the morphological types of ARSA. In this context, we proposed a new classification system of this anomaly. The secondary outcome was the evaluation of the demographic distribution of the lusoria artery.
RESULTS: Our search identified 47 articles describing 51 patients with ARSA. The typical course for ARSA is retroesophageal, being registered in 49 out of 51 patients. This malformation is frequently associated with Kommerell diverticulum (15 out of 51), troncus bicaroticus (7 out of 51), and aberrant origins of the right vertebral artery (7 out of 51). We observed a higher incidence of the condition among women (32 out of 51) compared to men (19 out of 51). From a demographic point of view, ARSA is more frequent in the \"44 to 57 years\" and \"58 to 71 years\" age ranges.
CONCLUSIONS: ARSA is a congenital malformation resulting from a defect in the development of the aortic arches. The imaging studies such as computer tomography play a defined diagnostic role.

摘要：
背景：右锁骨下动脉（ARSA）的异常起源，也被称为lusoria动脉，是先天性畸形，发病率为0.5-4.4%。大多数病例是偶然的，因为临床表现很少。计算机断层扫描（CT）在诊断和评估这些患者中很重要。
方法：我们在两个数据库中进行计算机化搜索，PubMed和EMBASE,对于2022年1月1日至2023年12月31日之间发表的文章，PROSPERO代码：CRD42024511791。符合入选条件的病例报告和病例系列显示右锁骨下动脉异常起源。主要结果是突出了ARSA的形态类型。在这种情况下，我们提出了这种异常的新分类系统。次要结果是评估lusoria动脉的人口统计学分布。
结果：我们的搜索发现了47篇描述51例ARSA患者的文章。ARSA的典型病程是食道后,51名患者中有49名被登记。这种畸形通常与Kommerell憩室（51个中的15个）有关，双骨（51个中的7个），和右椎动脉的异常起源（51个中的7个）。我们观察到女性（51人中有32人）的发病率高于男性（51人中有19人）。从人口统计的角度来看，ARSA在“44至57岁”和“58至71岁”年龄范围内更为频繁。
结论：ARSA是由主动脉弓发育缺陷引起的先天性畸形。诸如计算机断层摄影之类的成像研究起着明确的诊断作用。
