Abstract
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 prostheses 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.
Claims20
A method for sealing endoleaks in a patient arising from endovascular repair of abdominal aortic aneurysms in said patient which method comprises:
- identifying an abdominal aortic a patient;
- endovascularly repairing said aneurysm by catheter delivery of an endovascular prosthesis to the site of said aneurysm thereby inhibiting blood flow into the aneurysm;
- identifying one or more endoleaks in said patient treated for an abdominal aortic aneurysm with a endovascular prosthesis wherein said endoleak occurs at the the interface of the aortic wall to the end of the prosthesis or from defects within the prosthesis;
- and
- delivering through a microcatheter to the site or sites of said endoleaks a sufficient amount of a fluid composition under conditions wherein the fluid composition forms a coherent mass in situ which adheres to the walls of the vascular site and/or prosthesis thereby sealing the endoleaks.
