title: [Right-sided aortic arch with anomalous origin of the left subclavian artery: case report].
abstract: BACKGROUND
  A right-sided aortic arch is a rare congenital defect of the aorta with incidence of 0.05% to 0.1% reported in published series. Usually it is associated with congenital heart anomalies and esophageal and tracheal compression symptoms. We present a case of a right-sided aortic arch of anomalous left subclavian artery origin, accidentally revealed during multislice CT (MSCT) supraaortic branches angiography.
  
  
  METHODS
  A 53-year-old female patient was examined at the Outpatients' Unit of the Vascular Surgery University Clinic for vertigo, occasional dizziness and difficulty with swallowing. Physical examination revealed a murmur of the left supraclavicular space, with 15 mmHg lower rate of arterial tension on the left arm. Ultrasound of carotid arteries revealed 60% stenosis of the left subclavian artery and bilateral internal carotid artery elongation. MSCT angiography revealed a right-sided aortic arch with aberrant separation of the left subclavian artery that was narrowed 50%, while internal carotid arteries were marginally elongated. There was no need for surgical treatment or percutaneous interventions, so that conservative treatment was indicated.
  
  
  CONCLUSIONS
  A right-sided aortic arch is a very rare anomaly of the location and branching of the aorta. Multislice CT angiography is of great importance in the diagnostics of this rare disease.
