Abstract
Anatomic anomalies of the aortic arch have implications for clinical practice if their significance is understood. Our case study involves a cadaveric finding of the left vertebral artery originating directly from the aortic arch. Although this anatomical variation has been documented, the prevalence of this anomaly may be generally underestimated. After noting this anomaly, we analyzed 27 cases and found that four female cadavers had the left vertebral artery originating from the aortic arch rather than the left subclavian artery. With a prevalence rate of 14.8%, it would seem that this anomaly is more significant than previously thought, which could have implications for surgical practice.
摘要
如果能理解主动脉弓的解剖异常的意义，那么它们对临床实践就会有影响。我们的案例研究涉及在一具尸体上发现左椎动脉直接起源于主动脉弓。尽管这种解剖变异已有文献记载，但这种异常的发生率可能普遍被低估了。发现这一异常后，我们分析了27个案例，发现有4具女性尸体的左椎动脉起源于主动脉弓而非左锁骨下动脉。其发生率为14.8%，看来这种异常比之前认为的更为显著，这可能会对外科手术实践产生影响。
