A 1-month-old boy with respiratory distress underwent pulmonary artery banding after diagnosis of d-loop transposition of the great arteries and ventricular septal defect. Respiratory distress recurred after surgery. Angiography, esophagography, and magnetic resonance imaging showed left aortic arch, retroesophageal aorta, and right descending aorta. Surgery at 9 months of age showed a right-sided ligamentum arteriosum. Division of the ligamentum relieved the constriction of the esophagus and trachea caused by this rare form of vascular ring.
一名1个月大患有呼吸窘迫的男婴，在被诊断为大动脉d型转位和室间隔缺损后接受了肺动脉环扎术。术后呼吸窘迫复发。血管造影、食管造影和磁共振成像显示为左主动脉弓、食管后主动脉和右降主动脉。9个月大时手术发现动脉韧带位于右侧。切断韧带缓解了这种罕见血管环形式对食管和气管的压迫。
