Abdominal aortic aneurysm

Case contributed by Dr Ahmed Abdrabou

Presentation

Non specific abdominal pain. Abdominal ultrasonography revealed aortic aneurysm.

Patient Data

Age: 75 years
Gender: Male
CT

Fusiform aneurysmal dilatation of the infra-renal abdominal aorta that does not involve the iliac arteries. Mural thrombus is noted not affecting the major branches. Accessory renal artery is noted bilaterally. No signs of aortic rupture. Osteoporotic changes of patient vertebral column are noted.

Case Discussion

Atherosclerosis usually causes fusiform aneurysm due to focal weakening of the aortic wall that involves the whole circumference. Complication of aneurysm include rupture, thrombosis and dissection. Aneurysms require surgical intervention if its caliber exceeds 6 cm or is associated with complications. Otherwise endovascular graft/stent is the best option.
