Type B Aortic Dissection with Abdominal Aortic Aneurysm Rupture 1 Year after Endovascular Repair of Abdominal Aortic Aneurysm

We report a patient who developed a type B aortic dissection and ruptured his aneurysmal sac 1 year after endovascular abdominal aortic aneurysm repair (EVAR), despite standard follow-up. This 79-year-old man was presented to emergency room with acute abdominal pain and an acute lower limb ischemia. Computed tomography scan showed an acute type B aortic dissection feeding the aneurysmal sac of the EVAR. The aneurysm rupture occurred during imaging. Type B aortic dissection is a rare cause of aneurysmal rupture after EVAR. The first postoperative computed tomography scan should maybe include the arch and the descending thoracic aorta to rule out an iatrogenic dissection after EVAR.
