Insights
This study analyzed 111 congenital vascular ring cases, finding no intraoperative deaths. Postoperative mortality occurred in 2 neonates due to severe respiratory infections.
Area of Science:
- Cardiovascular Surgery
- Pediatric Surgery
- Thoracic Surgery
Background:
- Congenital vascular rings are rare anomalies affecting the aortic arch.
- Surgical correction is necessary for symptomatic patients.
Purpose of the Study:
- To review surgical outcomes for various types of congenital vascular rings.
- To analyze patient demographics and specific vascular ring classifications.
Main Methods:
- Retrospective analysis of 111 patients undergoing surgical correction for congenital vascular rings.
- Classification of vascular rings into five distinct groups based on anatomical variations.
Main Results:
- No intraoperative mortality was observed.
- Two postoperative deaths occurred in neonates due to severe bacterial respiratory infections.
- The study included 83 infants and 28 children with diverse vascular ring types.
Conclusions:
- Surgical correction of congenital vascular rings can be performed with no intraoperative mortality.
- Postoperative respiratory infections pose a significant risk, particularly in neonates.
Abstract:
Between October 1974 and May 1987, 111 congenital vascular rings were submitted to surgical correction. There were 83 infants (age: 5 days-12 months, median: 7 months; weight: 1.9-8.5 kg, median: 7.1 kg), and 28 children (age: 1-13 years, median: 3.5 years; weight: 7.5-48 kg, median: 26.5 kg). Patients were divided into five groups: (1) double patent aortic arch (44 cases), (2) double aortic arch with atresia in different parts of the left arch (36 cases), (3) right aortic arch with left ligamentum arteriosum (21 cases), (4) left aortic arch with aberrant right subclavian artery and truncus caroticus (8 cases), and (5) pulmonary artery sling (2 cases). We had no intraoperative mortality but in the postoperative period, 2 neonates died of severe bacterial infections of the respiratory tract.
