Tetralogy of Fallot Associated with Aberrant Right Subclavian Artery. Clinical Implications

Abstract Since the first description of Tetralogy of Fallot (ToF) in 1671 by Niels Stensen and in 1888 by Étienne-Louis Arthur Fallot, numerous papers have reported on this anomaly, along with its variants and concomitant cardiovascular anomalies. Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. Different from the left aberrant subclavian artery, occurrence of ARSA in ToF-patients has only casuistically been reported so far. The present study reports on two ToF-patients with ARSA. It is important to note that knowledge of the coexistence of both anomalies has highly practical points during surgical or endovascular corrections of congenital heart defects (including ToF).

摘要 自1671年尼尔斯·斯坦森（Niels Stensen）、1888年艾蒂安-路易·阿尔贝·法洛（Étienne-Louis Arthur Fallot）首次描述法洛四联症（Tetralogy of Fallot，ToF）以来，已有大量文献报道了该畸形及其变异型与伴发心血管畸形。迷走右锁骨下动脉（Aberrant right subclavian artery，ARSA）是最常见的主动脉弓畸形。与左侧迷走锁骨下动脉不同，迄今针对法洛四联症患者合并ARSA的报道仅为散在个案。本研究报道2例合并ARSA的ToF患者。需特别强调，明确两种畸形并存的情况，在包括法洛四联症在内的先天性心脏缺损的外科或血管内矫治术中，具有极高的临床实用价值。
