Aortic rupture is a rare but potentially catastrophic complication following a balloon aortoplasty for recoarctation. The treatment of aortic ruptures remains challenging. We present here a 9-year-old girl with Turner syndrome who experienced a life-threatening rupture in her aorta after a balloon aortoplasty for recoarctation. She was successfully rescued by the antegrade deployment of a commercially available iliac limb extension stent-graft via an ascending aortic conduit. Prudent balloon aortoplasty for recoarctation in patients with Turner syndrome is important due to their inherent aortopathy and previous surgical repairs. Possible reasons for an aortic rupture are oversized ballooning and the choice of balloon diameter based only on an angiographic measurement. In agreement with earlier reports, our case also confirms the importance of keeping a commercially available stent graft available to treat this complication that has potentially fatal consequences.
