Aneurysm after subclavian flap angioplasty repair of coarctation of the aorta

We report a case of aortic aneurysm at the site of subclavian flap angioplasty repair for coarctation of the aorta. The dilatation involved the lateral wall of the proximal descending aorta that had been constructed by the flap. Five other similar cases have been reported in the literature. Diligent long-term follow-up is needed after surgical repair of coarctation of the aorta to detect late complications such as restenosis or aneurysm formation.
