A rare form of vascular ring is presented consisting of a left cervical aortic arch, a right descending aorta, and a right ligamentum arteriosum in a symptomatic infant. The planning of its surgical interruption was complicated by absence of the left pulmonary artery and hypoplasia of the left lung. This case provides an exception to the surgical axiom that all vascular rings can be divided through the left side of the chest. It reveals the difficulty in evaluation of these lesions by barium swallow alone and emphasizes the importance of preoperative angiography to correctly define the anatomy. The surgical approach to a patient with an absent left pulmonary artery and hypoplastic lung requiring a contralateral thoracotomy is presented.
本文报道了一名有症状婴儿的罕见血管环类型，其由左颈总动脉弓、右位降主动脉和右动脉韧带组成。由于左肺动脉缺如和左肺发育不全，其手术切断的规划变得复杂。该病例为所有血管环均可经胸左侧进行分离这一手术原则提供了反例。它揭示了仅通过钡餐吞咽评估这些病变的困难，并强调了术前血管造影对正确界定解剖结构的重要性。本文还介绍了对于左肺动脉缺如和肺发育不全且需要对侧开胸手术的患者的手术入路。
