METHODS FOR TREATING ENDOLEAKS DURING ENDOVASCULAR REPAIR OFABDOMINAL AORTIC ANEURYSMS

摘要

Disclosed are methods for treating endoleaks arising from endovascular repai r 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 whic h composition in situ solidifies to seal the leak. Preferably, the biocompatib le fluid composition comprises a contrast agent to allow the clinician to visualize the sealing process.
