Late aneurysm of the distal aortic arch after repair of aortic interruption - A case report

Aneurysm formation after aortic coarctation repair is not a rare complicati on of post-coarctation of aorta repair. We describe the case of a 43-year-o ld woman who had undergone repair of an isolated interruption of the aortic arch 30 years earlier, who came to our hospital with progressive chest pai n, cough and dyspnea. A giant aortic aneurysm was revealed in the distal ao rtic arch by CT study. The patient underwent aneurysmectomy with total aort ic arch replacement using a Dacron graft through redo median sternotomy. An embryologic explanation of this patient's anomaly and the previous surgica l procedure are discussed for defining this rare clinical condition.
