Area of Science:

  • Cardiovascular Imaging
  • Radiology
  • Medical Diagnostics

Background:

  • Congenital aortic arch anomalies are rare vascular malformations.
  • The retro-oesophageal right aortic arch with aberrant left subclavian artery is a specific type of anomaly.
  • Early and accurate diagnosis is crucial for patient management.

Observation:

  • Three adult Saudi patients presented with this specific aortic arch anomaly.
  • Computer Tomography (CT) scans were utilized for diagnosis.
  • CT imaging clearly demonstrated the right aortic arch in all cases.

Findings:

  • Computer Tomography (CT) is effective in detecting and diagnosing the retro-oesophageal right aortic arch with aberrant left subclavian artery.
  • CT can confirm suspected anomalies from plain chest radiographs.
  • CT can identify vascular anomalies when radiographs suggest a mediastinal mass.

Implications:

  • CT imaging plays a vital role in the diagnosis of congenital aortic arch anomalies.
  • This case series reinforces the utility of CT in identifying rare vascular variations.
  • Improved diagnostic capabilities can lead to better patient outcomes for these rare conditions.
