Overlapping covered stents to exclude a postcoarctation stenting aortic aneurysm.
An 18-year-old boy who underwent coil occlusion of a patent ductus arteriosus and stenting for aortic coarctation at 13 years of age had evidence of re-stenosis. Cardiac catheterization and angiography showed a 25-mmHg gradient across the stent and a large aneurysm originating at midstent level. The aneurysm measured 2 cm in width and 4.3 cm in length. At a subsequent catheterization procedure, two 4.5-cm-long overlapping Cheatham platinum covered stents were implanted, completely excluding the aneurysm. Computed tomographic (CT) angiography 2 years later showed no evidence of endoleak or re-stenosis.
