Ma, Qixiang. "Deep learning based segmentation and detection of aorta structures in CT images involving fully and weakly supervised learning." Electronic Thesis or Diss., Université de Rennes (2023-....), 2024. http://www.theses.fr/2024URENS029.
Full textEndovascular aneurysm repair (EVAR) and transcatheter aortic valve implantation (TAVI) are endovascular interventions where preoperative CT image analysis is a prerequisite for planning and navigation guidance. In the case of EVAR procedures, the focus is specifically on the challenging issue of aortic segmentation in non-contrast-enhanced CT (NCCT) imaging, which remains unresolved. For TAVI procedures, attention is directed toward detecting anatomical landmarks to predict the risk of complications and select the bioprosthesis. To address these challenges, we propose automatic methods based on deep learning (DL). Firstly, a fully-supervised model based on 2D-3D features fusion is proposed for vascular segmentation in NCCTs. Subsequently, a weakly-supervised framework based on Gaussian pseudo labels is considered to reduce and facilitate manual annotation during the training phase. Finally, hybrid weakly- and fully-supervised methods are proposed to extend segmentation to more complex vascular structures beyond the abdominal aorta. When it comes to aortic valve in cardiac CT scans, a two-stage fully-supervised DL method is proposed for landmarks detection. The results contribute to enhancing preoperative imaging and the patient's digital model for computer-assisted endovascular interventions

Full textLa estenosis aórtica es la enfermedad valvular más frecuente en el tercer mundo. La historia natural de la enfermedad es bien conocida desde hace décadas, siendo una enfermedad con mal pronóstico a medio-corto plazo que hace necesario someter a estos pacientes a recambio valvular aórtico tras la aparición de síntomas. La forma mas común de estenosis aórtica, con flujo normal y gradiente alto, tiene un pronóstico excelente tras el recambio valvular aórtico, con una supervivencia similar a la de la población normal. Sin embargo, la estenosis aórtica de bajo-flujo y bajo-gradiente, es una entidad menos conocida y de peor pronóstico. Estos pacientes tienen una mortalidad mucho mayor tras recambio valvular aórtico y menor supervivencia a largo plazo. El diagnóstico en el bajo-flujo bajo-gradiente es vital para seleccionar correctamente los pacientes con estenosis aórtica que se beneficiarán de tratamiento quirúrgico, teniendo también valor pronóstico, dependiendo de la categoría de bajo flujo (Clásica o Paradójica) y otros determinantes como la presencia/ausencia de reserva contráctil del ventrículo izquierdo. Nuestra hipótesis fue que la estenosis aórtica de bajo-flujo y bajo-gradiente, pueden ser tratada con recambio valvular aórtico con una mortalidad hospitalaria similar a aquellos con flujo normal y alto gradiente. Los objetivos del proyecto fueron el análisis de resultados hospitalarios y a medio plazo (mortalidad hospitalaria, a 1 y 5 años) así como la clase funcional y recuperación de la función ventricular, en pacientes con estenosis aórtica de bajo-flujo bajo-gradiente sometidos a recambio valvular aórtico comparado con flujo normal alto-gradiente. Nuestros resultados nos llevan a la conclusión de que el recambio valvular aórtico en pacientes con estenosis aórtica de bajo-flujo bajo-gradiente se puede lograr con baja mortalidad quirúrgica, comparable con pacientes con flujo normal y alto gradiente. A pesar de que tener una mayor mortalidad a medio-plazo, los supervivientes exhiben una excelente clase funcional y desaparición de síntomas, que apoyan la indicación quirúrgica en estos pacientes.

Full textTiivistelmä Aorttaläpän ahtauma on yksi yleisimmistä läppävioista kehittyneissä maissa. Aorttaläpän ahtauma on etenevä sairaus, joka yleensä johtaa vakaviin henkeä uhkaaviin haittatapahtumiin. Aorttaläpän ahtauman hoitotavasta keskustellaan kiivaasti sydän- ja verisuonitautien tutkimuksessa siihen liittyvien kliinisten ja taloudellisten vaikutusten vuoksi. Aorttaläppäleikkausta, jossa aorttaläppä korvataan proteesilla, on aina pidetty vaikean oireisen aorttaläpän ahtauman hoidon kultaisena standardina, koska sen tulokset ovat erinomaisia, etenkin oireettomilla potilailla, joilla sydämen toiminta on hyvä. Leikkaus vaatii sydän-keuhkokoneen käyttöä ja aortan sulkemista, joiden kesto on suoraan yhteydessä kasvavaan sairastavuuteen ja kuolleisuuteen erityisesti potilailla, joilla on muitakin sairauksia. Niinpä tekniikat, jotka lyhentävät sydän-keuhkokoneen käyttöaikaa ja aortan sulkuaikaa, voivat mahdollisesti parantaa aorttaläppäleikkauksen tuloksia. Tässä tutkimuksessa osoitettiin, että ompeleettoman biologisen Perceval-läppäproteesin käyttö vähensi merkittävästi leikkauksen kestoa. Tämä oli yhteydessä parantuneisiin lyhyen ja pitkän aikavälin tuloksiin leikkauksen jälkeen. Ompeleettoman biologisen Perceval-läppäproteesin käyttö voi helpottaa aorttaläppäleikkausta, koska se voidaan asentaa vähemmän kajoavasta avauksesta, ja siihen liittyy vähemmän punasolusiirtoja rintalastan kokoavaukseen verrattuna, myös silloin kun käytetään kokoavausta ja perinteisiä stenttibioproteeseja. Voisi olla odotettavaa, että keskisuuren tai suuren riskin potilaat hyötyisivät enemmän leikkauksesta, jossa yhdistyvät toimenpiteen nopeus ja vähäisempi kajoavuus. Katetriteitse asennettuun biologiseen keinoläppään (TAVI) verrattuna ompeleeton biologinen Perceval-läppäproteesi oli yhteydessä parempaan laitteen toimimiseen ja pienempään paravalvulaariseen vuotoon. Muut tulokset heti leikkauksen jälkeen ja yhden vuoden seurannassa olivat samanlaisia. Lopuksi voidaan todeta, että aorttaläppäleikkaukseen ompeleettomalla biologisella Perceval-läppäproteesilla liittyi erinomainen hemodynamiikka levossa ja korkean työkuorman aikana. Stressin aikaisen tehokkaan aorttaläpän aukon pinta-alan merkittävä kasvu osoittaa, että ompeleeton biologinen Perceval-läppäproteesi on hyvä valinta potilaille, joilla on pieni aorttaläpän aukko tai kun on odotettavissa proteesin ja potilaan yhteensopimattomuutta
