Abstract
The Norwood operation as first-stage palliation for hypoplastic left heart syndrome has been standardized in most centers. However, in the presence of anomalies of aortic arch anatomy or position, or other anatomical variants, important modifications of the procedure may become necessary. This report summarizes surgical techniques to address these challenges.

Abstract
BACKGROUND Vascular rings are aortic arch anomalies with a spectrum of manifestations ranging from asymptomatic lesions detected incidentally to an acute presentation secondary to tracheo-esophageal compression. Circumflex retro-esophageal aortic arch is an extreme form of true vascular ring. It remains an uncharted territory to many surgeons. METHODS A comprehensive search of peer reviewed journals was completed based on the key words, "Circumflex aorta," "Circumflex retro-esophageal aorta" and "circumflex arch" using Google scholar, Scholars Portal Journals and PubMed. The reference section for each article found was searched to obtain additional articles. Literature on the circumflex aorta was reviewed starting from the embryogenesis to the latest management strategies. RESULTS Right circumflex aorta is more prevalent compared to left circumflex aorta. It can occur in isolation or in association with other intracardiac lesions. Mainly presents in children, however reported in adults too. The presentation may vary from asymptomatic lesion to acute respiratory distress secondary to airway compression. Computerized tomography (CT) and magnetic resonance imaging (MRI) are important tools in delineating the vascular anatomy. Aortic uncrossing is the definitive procedure. However, the role of concomitant tracheobronchopexy is emerging. Native tissue-to-tissue anastomosis is commonly preferred, but cases of extra-anatomic grafts are reported. CONCLUSION Circumflex aorta is amenable to complete repair. Preoperative delineation of anatomy is important for successful surgical outcome. Division of the retro-esophageal segment is crucial in relieving the compressive symptoms. In addition, tracheobronchopexy is helpful in addressing residual tracheomalacia but this accounts for a high-risk surgery.

Abstract
The circumflex aorta is a rare type of true vascular ring anomaly. It consists of a retroesophageal right aortic arch, a left-sided descending thoracic aorta, and a left-sided ligamentum arteriosum. The “aortic uncrossing procedure” described by Planché and Lacour-Gayet is the procedure of choice for managing this aortic anomaly in patients with a biventricular heart. The presence of a circumflex aorta in a patient with heterotaxy syndrome and univentricular congenital heart disease requiring Norwood palliation is highly unusual. We report such a case and describe our approach to its surgical management.

Fetal Aortic Arch Anomalies: Key Sonographic Views for Their Differential Diagnosis and Clinical Implications Using the Cardiovascular System Sonographic Evaluation Protocol. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2016; 35:237-251. [PMID: 26715656 DOI: 10.7863/ultra.15.02063] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2015] [Accepted: 05/23/2015] [Indexed: 06/05/2023]
Abstract
Aortic arch anomalies are present in 1% to 2% of the general population and are commonly associated with congenital heart disease, chromosomal defects, and tracheaesophageal compression in postnatal life. The sonographically based detection of aortic arch anomalies lies in the 3-vessel and trachea view. Although highly sensitive, this view alone does not allow identification of the aortic arch branching pattern, which prevents an accurate diagnosis. The systematic addition of a subclavian artery view as part of a standardized procedure may be useful in the differential diagnosis of these conditions. We describe the sonographic assessment of fetal aortic arch anomalies by combining 2 fetal transverse views: the 3-vessel and trachea view and the subclavian artery view, which are included in the cardiovascular system sonographic evaluation protocol. We also review the sonographic findings and the clinical implications of fetal aortic arch anomalies.
