Management of abdominal aortic aneurysms 34

Salma El Batti, Iannis Ben Abdallah.
Abstract
The abdominal aortic aneurysm is a permanent dilation of the aorta with a diameter of more than 30 mm. It can be strictly infra-renal or be located opposite the origin of the digestive and renal arteries (complex aneurysm). Most often fortuitous, the diagnosis must seek a secondary location of the aneurysmal disease (thoracic aorta, popliteal artery) as well as other manifestations of atheromatous disease. The natural course of the aneurysm is rupture, the severity of which is such that preventive and elective surgical treatment is warranted when the aneurysm reaches 55 mm or if it grows rapidly. Regular monitoring of the diameter by Doppler ultrasound is necessary when the diameter is less than 45 mm; beyond this threshold, a CT angiogram and a specialist consultation in vascular surgery are necessary. Flattening - graft and stent exclusion are the two possible surgical options; the anatomy of the aneurysm and the patient’s comorbidities determine the choice of surgical technique.
