Abstract


Los pacientes con aneurismas toracoabdominales tipo IV se caracterizan anatómicamente por presentar una dilatación aórtica visceral determinando la ausencia de un cuello proximal aórtico adecuado para el anclaje de las endoprótesis convencionales. Para tal fin existen injertos especialmente diseñados con fenestraciones. El propósito de la presentación es mostrar nuestra experiencia con este abordaje. Se presenta nuestra experiencia en la utilización de endoprótesis fenestradas. Fueron tratados seis pacientes. Todas las endoprótesis fueron implantadas con éxito, respetando 20 vasos viscerales. Este abordaje constituye hoy una alternativa válida para el tratamiento de este grupo de pacientes candidatos a cirugía convencional de alto riesgo.
