On three unusual cases of symptomatic abdominal aortic aneurysms, the authors demonstrate the need for satisfactory erudition of a vascular surgeon, who must manage the above serious conditions. In the first case, the authors deal with a symptomatic aneurysm of the abdominal aorta and a homolateral dystopy of the right kidney co-existence. In the second case, the authors describe a rare, nevertheless a very serious communication between a vein and an adjacent aneurysm. In the third case, the authors prefer the left-sided retroperitoneal approach in the management of the juxtarenal AAA in combination with a "hostile abdomen".
