“Etiologies include fibromuscular dysplasia (FMD), atherosclerosis, and pseudoaneurysms that may occur after trauma.”
“RAAs related to FMD should be considered when there is a classic ‘string of beads’ appearance to the renal artery or when aneurysms occur in younger women, especially when associated with hypertension.”
“Pseudoaneurysms typically occur after trauma and are usually located within the parenchyma of the kidney.”
“Other aneurysms, not related to FMD or trauma, typically occur at branch points in the renal artery.”
Decision to repair a renal artery aneurysm depends on patient age, gender, aneurysm size, and presence of uncontrolled hypertension.
