Endovascular repair of a ruptured abdominal aortic aneurysm after endovascular aneurysm repair due type IB endoleak associated with a late fistula between the abdominal aorta and a retroaortic left renal vein

A ruptured abdominal aortic aneurysm after endovascular aneurysm repair with an arteriovenous fistula between the aneurysm sac and a retroaortic left renal vein is an extremely rare complication. This case describes an 81-year-old man who developed an aorto-left renal vein fistula owing to a type IB endoleak 2 years after endovascular aneurysm exclusion. The leak was repaired with a left endograft limb extension. Endovascular techniques are attractive and feasible alternatives and can play an essential role in reinterventions. This report is the first of an aorto-left renal vein fistula owing a type IB endoleak after an endovascular aneurysm repair.
