View larger version (119K): [in a new window]   Figure 1 Initial implantation of Palmaz 308 stent in a 15-year-old patient with native coarctation of the aorta and 18-month angiography follow-up. (A and B) Initial postero-anterior and lateral angiography showed an 8-mm coarctation with a 35-mm Hg pressure difference. (C and D) The diameter increased to 18 mm immediately after stent implantation. (E and F) Repeat angiography 18 months later shows no recurrent obstruction and no aneurysm. There is some remodeling of the aorta with minimal neointimal proliferation.
