Patch Grafts or Tubular Grafts in the Repair of Coarctation of the Aorta

The occurrence of aneurysms after repair of aortic coarctation with patch graft and tubular graft techniques was studied. In the patch graft group, 3 out of 6 re-investigated patients developed aneurysms; 2 of them after several years. It is suggested that the causes of aneurysms originate from mechanical factors. In the tubular graft group, 2 out of 18 patients developed aneurysms. In this group, the aneurysms seemed to be due to infection.
