Peak systolic velocities in the abdominal aorta average 110cm/s in a population with an average age of 12 years. This is called fasting. Grading of stenosis severity in the aorta by Doppler criteria has also not been extensively studied because of the rarity of isolated abdominal aortic stenosis. Fasting helps prevent gas buildup in the belly area, which could affect the results. Another type of genetic inheritance includes disease states where the aortic wall is abnormal because of an inherited defect in the structure of fibrillin (gene locus FBN1) such as Marfan and Ehlers-Danlos syndromes.

It courses medially then crosses over the iliac vessels and travels along the pelvic sidewalls before turning anteriorly and medially to enter the fundus of the bladder. This corresponds to the bladder depth and width, respectively. Most aneurysms are infrarenal. The overhydrated patient, pregnant patient, or one with a full bladder may have mild hydronephrosis.
