1. A method of treating an aortic aneurysm in a subject, the method comprising:
puncturing an artery to define to define an arterial puncture site;
after puncturing the artery, delivering an endograft to the aortic aneurysm;
advancing a shunt through a venous puncture site of a vein to access the arterial puncture site of the artery, the arterial puncture site disposed within the aortic aneurysm or upstream of the aortic aneurysm; and
securing the shunt to the artery and vein by deploying i) an arterial sealing structure coupled to a distal end of the shunt, and ii) deploying a venous sealing structure coupled to a proximal end of the shunt, thereby enabling fluid to flow from the artery to the vein.
