Disclosed are methods for treating endoleaks arising from endovascular repair of abdominal aortic aneurysms. The disclosed methods involve the in situ sealing of endoleaks after placement of an endovascular prosthesis in the abdominal aorta. Sealing of endoleaks is achieved by injection of either a biocompatible polymer or prepolymer fluid composition into the endoleak which composition in situ solidifies to seal the leak. Preferably, the biocompatible fluid composition comprises a contrast agent to allow the clinician to visualize the sealing process.

L'invention concerne des méthodes de traitement d'endofuites provoquées par la réparation endovasculaire d'anévrismes aortiques abdominaux. Les procédés décrits comportent l'obturation in situ d'endofuites après la mise en place d'une prothèse endovasculaire dans l'aorte abdominale. L'obturation d'endofuites est mise en oeuvre par l'injection d'un polymère biocompatible ou d'une composition fluide de prépolymère dans l'endofuite, cette composition se solidifiant in situ pour obturer la fuite. De préférence, la composition fluide biocompatible contient un agent de contraste pour permettre au chirurgien de visualiser le processus d'obturation.
