Abstract:
(EN) A method and apparatus for combining therapeutic pulsed or continuous-wave ultrasound with diagnostic pulsed ultrasound are described. In both a therapeutic mode and in a diagnostic mode, the ultrasound is administered from a single probe (128) to a patient (118) suffering from thrombosis. The ultrasound can have the same or different frequency ranges in the diagnostic and therapeutic modes. The pulsed or continuous-wave ultrasound in the therapeutic mode enhances a lysing effect of a thrombolytic agent (110). The pulsed ultrasound in the diagnostic mode allows monitoring of blood flow to locate a thrombus (122), to determine an optimal window to administer the therapeutic pulsed ultrasound, and to detect when recanalization has occured. If an operator attends the device, a graphical display (600) operates during the diagnostic mode to display an image representative of the blood flow.
(FR) La présente invention concerne un procédé et un appareil permettant de combiner des ultrasons thérapeutiques par onde continue ou par impulsion avec des ultrasons diagnostiques par impulsion. Dans le mode thérapeutique et dans le mode diagnostique, on administre les ultrasons à partir d'une seule sonde à un patient souffrant de thrombose. Ces ultrasons peuvent avoir les mêmes plages de fréquence ou des plages différentes dans ces deux modes. Les ultrasons par onde continue ou par impulsion du mode thérapeutique renforce l'effet lytique d'un agent thrombolytique. Les ultrasons par impulsion du mode diagnostique permettent de surveiller le débit sanguin de façon à localiser un thrombus, afin de déterminer une fenêtre optimum pour administrer les ultrasons thérapeutiques par impulsion, et de détecter quand la reperméation est survenue. Si un opérateur se sert de ce dispositif, un afficheur graphique fonctionne durant le mode diagnostique de façon à afficher une image représentative du débit sanguin.
