OBJECTIVES
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.
METHODS
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.
RESULTS
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%).
CONCLUSION
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.
目的
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。
方法
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。
结果
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%）。
结论
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。
