Non-recognition of a critical aortic arch branch variation at surgery, with fatal consequences, prompted a retrospective analysis of the prevalence of aortic arch branch variations in the South African population.
Three hundred and twenty aortic arch angiograms were analysed from existing records (January 1988--March 1998) of the vascular unit, Department of Surgery, University of Natal.
Aortic arch branch variations were observed in 17 cases (5.3%). These variations were as follows: (i) 11 cases with two primary branches (3.4%); (ii) 1 case with three primary branches (0.3%); and (iii) 5 cases with four primary branches (1.6%).
The clinical presentations which these variations give rise to are well known and may present during the first days of life or later in adulthood, or remain clinically silent. Non-recognition of the latter situation in the presence of vascular trauma may have fatal consequences.
手术中未识别出关键的主动脉弓分支变异会导致致命后果，这促使对南非人群中主动脉弓分支变异的患病率进行回顾性分析。
对纳塔尔大学外科系血管单元现有记录（1988年1月至1998年3月）中的320例主动脉弓血管造影进行分析。
在17例（5.3%）中观察到主动脉弓分支变异。这些变异如下：（i）11例有两个主要分支（3.4%）；（ii）1例有三个主要分支（0.3%）；（iii）5例有四个主要分支（1.6%）。
这些变异所引起的临床表现是众所周知的，可能在生命的最初几天出现，或在成年后期出现，或在临床上保持无症状。在存在血管创伤的情况下未识别出后一种情况可能会导致致命后果。
