Dr. GuimaraensEl Dr. Leopoldo Guimaraens es especialista en Radiología y especialista en Neuroradiología Intervencionista en el Hospital Lariboisière de Paris, el centro más avanzado del mundo en esta especialidad. En la actualidad , el Dr. Guimaraens es Responsable del Servicio de Intervencionismo Neurológico del Hospital San Juan de Dios de Barcelona y Co-Director del Servicio de  Terapéutica Endovascular y  Percutánea del Hospital Nuestra Señora del Rosario de Madrid, Junto con el Dr. Alfredo Casasco, (donde dirige) y con la colaboración de un equipo de cuatro especialistas de reconocido prestigio dentro de su ámbito de actuación.

El Drs. Guimaraens y Casasco han sido pioneros en el desarrollo y transformación de la neurorradiología intervencionista, proceso que quedó plasmado en dos trabajos que obtuvieron el primer premio de la Sociedad Americana de Neurorradiología. Ha publicado más de cien trabajos de la especialidad y escrito 21 artículos en libros de Neurorradiología Intervencionista y ha presentado conferencias y comunicaciones en Congresos nacionales e internacionales  con más de 300 trabajos.

Es uno de los mayores especialistas a nivel internacional en el tratamiento endovascular del ictus isquémico y hemorrágico, aneurismas intracraneales, malformaciones arteriovenosas intracraneales, malformaciones arteriovenosas en la infancia, malformaciones vasculares de la médula espinal y de tumores de la base de cráneo mediante desvascularización.
