"THE DOCTOR CALLED ME ABOUT A PREVIOUS EVAR WHICH HAD A LEAK. AFTER IMAGES WERE ACQUIRED, IT WAS THEN REALIZED THE DEVICE WHICH WAS IMPLANTED WAS A TREO. SCAN SHOWS THAT THE AORTA HAS REMODELED.

THE RIGHT ILIAC LIMB SEEMS TO HAVE SUCKED UP INTO THE ANEURYSM AND VERY LITTLE IS LEFT IN THE RIGHT COMMON ILIAC ARTERY. THERE IS POTENTIAL OF A TYPE 1B LEAK." PATIENT OUTCOME: "PATIENT WILL LIKELY BE REFERRED TO ANOTHER INSTITUTE FOR A PMEG REPAIR."
