Vascular rings and slings

Dr Henry Knipe et al.

Vascular rings and slings refer to the congenital vascular encirclement of the oesophagus and/or trachea by anomalous/aberrant vessels. 

Vascular rings are rare, occurring in <1% of patients 1. No gender or ethnic predispositions have been identified 3

Many vascular rings and slings are asymptomatic although they can present in paediatric patients with wheezing/stridor, recurrent respiratory infections and/or dysphagia lusoria

Vascular rings can be classified as complete (mostly symptomatic) or incomplete (mostly asymptomatic) 5

Aetiology

Causes of vascular rings and slings commonly include 1:

Associations

Radiographic features will differ depending on the underlying anomaly.

Plain radiograph

Abnormal contour to the trachea may be visible on plain film, as may a right sided aortic arch.

Fluoroscopy

This may similarly demonstrate vascular indentations on the oesophagus on barium swallow. The pattern of indentations on the lateral oesophagram helps to narrow the differential:

CT/MRI
  • allow precise demonstration of the anomaly
