Ultrasound in Abdominal Aorta and Iliac Arteries Atherosclerotic Disease

The echocolor Doppler examination of the abdominal aorta must inform on its profile, its wall and on the possible presence of atherosclerotic pathologies.

The ultrasound investigation is the best way to diagnose an abdominal aortic aneurysm with an accuracy of almost 100%: sonographically the most common appearance of an abdominal aorta aneurysm is a dilated vessel with associated atherosclerotic changes.

The ultrasound evaluation of the axial aneurysm diameters and the exact relationship of the aneurysm with the origin of the renal arteries and the bifurcation are required. Dilatation or stenosis of the common iliac arteries should also be documented.

The ultrasound evaluation of the iliac arteries provides the description of the artery wall and requires the documentation of possible associated pathologies.

In this lesson the sonographic characteristics of the atherosclerotic diseases (thrombosis, aneurysms and dissections) of the abdominal aorta and of the iliac arteries are presented.
