INTRODUCTION: Acute aortic dissection after endovascular repair of an aortic aneurysm is a rare but serious condition, with potential complications that can result in the death of the patient.
REPORT: This is the case of a patient diagnosed with a type IV thoraco-abdominal aneurysm with involvement of both iliac arteries who underwent endovascular repair with a four fenestration device and a left iliac branch. One month after the procedure, the patient presented with a type B acute aortic dissection that extended from the left subclavian artery to the proximal stent of the fenestrated graft. This dissection was treated by thoracic endovascular aortic repair, and after a problematic post-operative period, the patient was discharged after 30 days.
DISCUSSION: Occurrence of an acute aortic dissection after endovascular repair of an aortic aneurysm has rarely been reported in the literature. Development of these dissections has been related to factors such as excessive oversizing, use of devices with active fixation systems, or injuries during the procedure, although it is believed that the late onset would indicate that it was a de novo dissection. The presence of an aortic dissection can lead to the collapse and occlusion of the previous endograft and even to aortic rupture, and mortality in reported cases reaches 30%. The authors suggest that endovascular treatment should be considered in these patients.
