Usefulness of intracoronary imaging techniques in the percutaneous treatment of in-stent restenosis

We report a case of very late bare-metal stent restenosis, in which assessment by two intracoronary imaging techniques (intravascular ultrasound and optical coherence tomography) revealed the underlying mechanism (neoatherosclerosis) and facilitated percutaneous treatment (direct bare-metal stent-in...

Description
Summary:We report a case of very late bare-metal stent restenosis, in which assessment by two intracoronary imaging techniques (intravascular ultrasound and optical coherence tomography) revealed the underlying mechanism (neoatherosclerosis) and facilitated percutaneous treatment (direct bare-metal stent-in-stent). We also take the opportunity to briefly describe the advantages and limitations of both techniques in this pathology. Resumo: Neste artigo fazemos referência a um caso de reestenose muito tardia de um stent convencional que, através de duas técnicas de diagnóstico intracoronário, ultrassonografia intravascular (IVUS) e tomografia de coerência ótica (OCT), permite dar a conhecer o seu mecanismo subjacente (neoaterosclerose) e facilita o seu tratamento percutâneo (stent convencional direto intrasent). Aproveitamos também a ocasião para fazer uma breve descrição das vantagens e limitações de ambas as técnicas neste tipo de patologia.
