[Stenting in a recently implanted stent in a saphenous vein graft for optimizing angiographic results]. / Implante de stent dentro de stent recém implantado em ponte de veia safena para otimização do resultado angiográfico.

ABSTRACT

A 60 year-old woman with progressive angina who had been submitted to saphenous bypass-graft to right coronary artery and a left mammary artery graft to anterior descending artery eight years previously, underwent implantation of a Gianturco Roubin II stent in the proximal third of the saphenous vein graft. The result was suboptimal by persistence of a residual stenosis probably due to prolapse of atherosclerotic material through the coil spaces. Another stent (Palmaz-Schatz biliar stent) was implanted at the previously stented site with no residual stenosis. Another Palmaz-Schatz biliar stent was successfully implanted in the distal body of the graft to treat another lesion (passing through the previously stents without difficulty). Stenting a stent, in selected situations, is a useful tool to optimize the angiographic result of stent implantation.
