Anomalous unilateral pulmonary vein in a patient with aortic coarctation

A 34-year-old woman with previous aortic coarctation repair at the age of 5 years was referred for review. She was in good health. On clinical examination, there was no blood pressure difference between the arms, but pedal pulses were weak. A contrast-enhanced 64-slice thoracic CT scan was performed to assess the coarctation repair.
