RESUMEN

El stent cubierto con membrana se ha reportado como un dispositivo útil para corregir lesiones angiográficas específicas, así como complicaciones potenciales secundarias a procedimientos de intervencionismo coronario. El stent cubierto con membrana de (Jostent-Jomed) está compuesto por una fina capa de politetrafluoroetileno (PTFE) que se localiza entre dos stents metálicos. En esta revisión retrospectiva el stent de PTFE se utilizó en varias lesiones y situaciones angiográficas tanto en arterias coronarias como en injertos venosos. Nuestra experiencia consistió de 17 pacientes que fueron tratados por diferentes indicaciones clínicas y angiográficas: perforación coronaria en dos pacientes (pts), injertos venosos con trombo y cambios degenerativos en ocho (pts), aneurismas coronarios en 4 (pts) y trombo grande refractario a tratamiento habitual en otros 3 casos. Nuestros resultados con el stent de PTFE mostraron una tasa de éxito clínico del 100% sin complicaciones durante la fase hospitalaria y en el seguimiento clínico a 10 ± 3 meses sólo tres pacientes tuvieron algún evento cardíaco adverso mayor. La indicación potencial para el implante del stent de PTFE en injertos venosos todavía no se ha puntualizado; sin embargo a la luz de varios estudios pareciera haber poco beneficio en esta circunstancia. Por otro lado la perforación y el aneurisma coronario parecen ser las indicaciones más recomendables para la aplicación de este dispositivo.
