We report a fatal dissection of the descending aorta as a complication after a two-staged implantation of a stent to relieve aortic coarctation in a young female with Turner's syndrome. Implantation of the stent, with dilation up to 70 percent, and half a year later re-dilation to 100 percent, was without any complication. A week after the re-dilation, however, the patient suffered acute dissection of the descending aorta. We initially stabilized the situation, but some days later her condition deteriorated, and she died. We discuss the various options for treating coarctation and re-coarctation. As far as we know, this is the first description of implantation of a stent in the setting of coarctation in Turner's syndrome, albeit with an unfortunate conclusion.
