NFLAMMATORY ABDOMINAL AORTIC ANEURYSM – ENDOVASCULAR TREATMENT

CASE REPORT

Abstract

INTRODUCTION: Inflammatory Abdominal Aortic Aneurysms are characterized by a dense perianeurysmal inflammatory reaction, characterized by the presence of a thickened arterial wall and increased laboratory tests of inflammatory activity. CASE REPORT: A 55-year-old female patient with a CT scan of the abdomen showing the presence of an infrarenal Abdominal Aortic Aneurysm measuring 14.1 x 8.1 x 9.1 cm. She underwent endovascular repair after remission of the inflammatory activity with the use of corticosteroids and methotrexate. After 6 months of treatment, the presence of type II Endoleak was observed. DISCUSSION: Inflammatory aneurysms should be suspected in patients with aortic aneurysms with an atypical epidemiological history. The incidence of rupture tends to be similar to that of non-inflammatory aneurysms. Open surgical resection is difficult due to the extensive fibrous and inflammatory reaction and adhesion to adjacent structures. The application of endovascular surgery for this type of aneurysm is considered promising. Type II endoleak is the most frequent and is characterized by a retrograde reflux through the aortic branches. For cases in which there is no expansion, the recommendation is to carry out follow-up with serial imaging tests.
