Treatment of Recoarctation after Catheter Intervention for Aortic Coarctation Using a Balloon-Expandable Stent Graft within a Self-Expanding Stent Graft
Abstract

We successfully treated re-coarctation following balloon angioplasty for aortic coarctation in an 11-year-old girl using a novel sequential stent grafting approach. A self-expanding stent graft was first deployed, followed by the implantation of a balloon-expandable stent graft within the initial stent. This strategy ensured optimal luminal expansion and minimized vascular stress. The patient had previously undergone balloon angioplasty at age 9, but restenosis developed. After the staged stent grafting at age 11, the pressure gradient across the lesion was reduced from 60 mmHg to 10 mmHg, with no procedural complications. To the best of our knowledge, no prior reports have described this technique. We believe this method offers a promising option for the management of similar complex re-coarctation cases.
