VACTERL Association

Definition

A non random association of congenital anomalies, diagnosed with at least three of vertebral, anal, cardiac, tracheo oesophageal, renal and limb defects.

Aetiology

  • Mostly sporadic, with no single cause
  • Maternal diabetes is a recognised risk factor
  • About 1 in 10,000 to 40,000 births

Clinical Features

  • Vertebral anomalies in 60 to 80%, with hemivertebrae and segmentation defects
  • Anal atresia in 55 to 90%
  • Cardiac defects in 40 to 80%
  • Tracheo oesophageal fistula in 50 to 80%
  • Renal anomalies in 50 to 80%
  • Limb anomalies in 40 to 50%, mainly radial ray deficiency and thumb hypoplasia
  • Single umbilical artery and growth deficiency in some

Investigations

  • Spine radiographs and MRI for congenital scoliosis and tethered cord
  • Echocardiogram and renal ultrasound
  • Chromosome breakage test to exclude Fanconi anaemia
  • Chromosomal microarray

Differential Diagnosis

Management

  • Neonatal surgery. Airway, cardiac and anorectal anomalies take priority
  • Spinal surveillance. Serial radiographs for progression, see congenital scoliosis
  • Hand reconstruction. Centralisation and pollicisation for radial deficiency, see radial club hand

Complications

  • Progressive congenital scoliosis from unbalanced hemivertebrae
  • Neurological deficit from an untreated tethered cord
  • Recurrent radial deviation after centralisation

Prognosis

  • Normal intellect in most
  • Early mortality relates to cardiac and airway lesions
