BACKGROUND: Vascular ring is a rare cause of recurrent respiratory infections, dysphagia and stridor. Surgical repair is considered safe but the long-term outcomes are unclear. The purpose of this study was to investigate the mortality and morbidity following vascular ring surgery in a single institution.

MATERIALS AND METHODS: This retrospective study covers operations done at Aarhus University Hospital, Denmark between October 1983 and May 2015. Medical records were reviewed focusing on early complications and long-term complaints up to September 2017.

RESULTS: A total of 23 patients with median age of 1.4 years (range 0.008-64 years) were operated for vascular ring. Median follow-up was 6.8 years (range 2.4-34 years). Presenting symptoms were stridor (52%), dysphagia or vomiting (52%) and recurrent respiratory infections (48%). There were no early or late deaths. Three months postoperatively, 59% reported no respiratory complaints and 50% reported normal eating habits. Long term, only 14% had no complaints. In particular, asthma (36%), persistent stridor (18%) and recurrent respiratory infections (32%) were frequent. A high number of patients developed mental illness (27%).

CONCLUSION: Surgery for vascular ring can be performed with low early and long-term mortality. Despite good three months outcome, the majority of patients had long-term respiratory issues. Oesophageal morbidity was low.

LEVEL-OF-EVIDENCE: 2B.
