A 9-year-old boy, with a history of repair of severe coarctation of the aorta through balloon angioplasty 2 weeks ago, presented in the emergency paediatric department with symptoms consistent with transient cerebral ischaemia. MRI revealed an area of cerebral infarction in the right frontal lobe. Causes of cerebral ischaemia after aortic coarctation repair are briefly discussed.
