A Case of Treatment for Pararenal Abdominal Aortic Aneurysm Using Reverse VIABAHN Sandwich Technique EVAR

Generally speaking, pararenal abdominal aneurysm (PRAAA) is not well suited to EVAR because the length of its proximal neck is too short for EVAR. Recently in Europe and America, PRAAA is treated with fenestrated EVAR, branched EVAR, or chimney EVAR. The purpose of this case was to evaluates the efficacy of the reverse VIABAHN sandwich technique for PRAAA. An 85-year-old man with a medical history of angina pectoris, diabetes mellitus, hypertension, dyslipidemia, intraductal papillary mucinous neoplasm, postoperative prostatic cancer, cholecystolithiasis, and postoperative inguinal hernia was indicated AAA in a health examination two years ago. CT showed that there was AAA with a diameter of 40 mm under the right renal artery, and the left renal artery was branched from AAA. CT follow up at two years revealed AAA developed slowly expanding to a diameter of 47 mm.
