摘要

背景:反常右锁骨下动脉(ARSA)是一种罕见的血管畸形,其定义是右锁骨下动脉起源于主动脉,位于左锁骨下动脉(LSA)的远端。一名83岁的女性在解剖教学中解剖尸体时发现了一条ARSA,与之前报道的病例相比,它的管腔异常狭窄:材料:通过进一步解剖和测量,确定了该 ARSA 变体的具体形态特征。为了与该病例进行比较,对尸体病例报告进行了系统回顾,并对 ARSA 的尺寸进行了定量评估:结果:与 LSA(152.55 平方毫米)相比,该 ARSA 变体的管腔异常狭窄(8.22 平方毫米),ARSA 与 LSA 之比为 0.24:LSA之比为0.24。系统综述包括 17 项研究,共 23 例 ARSA。在这些病例中,20 个病例包含 ARSA 直径的详细信息,其中 19 个病例的 ARSA 直径比本病例更宽。在同时测量 ARSA 和 LSA 直径的所有研究中,发现 ARSA 明显比 LSA 宽(ARSA 与 LSA 的平均比值:1.49,范围:1.09-2.00)。这些研究还报告了其他一些变异,如同时存在的主动脉弓分支异常以及根据椎体水平和与主动脉弓的关系定义的 ARSA 的不同起源:本病例报告中的ARSA异常狭窄,以前的文献中从未描述过。由于关于ARSA形态如何影响临床结果的证据有限,因此需要进一步研究,以便更好地指导ARSA的管理。

Unusual morphology of an aberrant right subclavian artery: a case report and systematic review of cadaveric studies .

Background: An aberrant right subclavian artery (ARSA) is a rare vascular anomaly defined by the origin of the right subclavian artery from the aorta, distal to the left subclavian artery (LSA). An ARSA was found in an 83-year-old female during cadaveric dissection for anatomy teaching, which had an unusually narrow lumen compared to previously reported cases.

Materials and methods: The specific morphology of this ARSA variant was characterised by further dissection and measurements. A systematic review of cadaveric case reports with quantitative evaluation of ARSA dimensions was conducted for comparison with this case.

Results: This ARSA variant exhibited an unusually narrow lumen (8.22 mm²) compared to the LSA (152.55²), with an ARSA: LSA ratio of 0.24. The systematic review included 17 studies with 23 cases of ARSAs. Of these cases, 20 contained details of ARSA diameter, 19 of which were wider than in this case. In all studies where both ARSA and LSA diameters were measured, ARSA was found to be significantly wider than LSA (mean ratio of ARSA to LSA: 1.49, range: 1.09-2.00). Several other variations were reported in these studies, such as concomitant aortic arch branch anomalies and differing origins of ARSA as defined by vertebral level and relation to the aortic arch.

Conclusions: This case report presents an unusually narrow ARSA which has not been previously described in the literature. As there is limited evidence on how ARSA morphology affects clinical outcomes, further research is needed to better inform management of ARSAs.

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
