Clinical presentation of atheroembolic acute AKI
What is the typical clinical presentation of atheroembolic acute AKI?
The presence of diffuse atherosclerosis predisposes a patient to renal atheroemboli, which is characterized by a stair-step pattern to the increase in creatinine that occurs days to weeks after the procedure with little or no recovery of kidney function.
What is the differential diagnosis for kidney failure following cardiac catheterization?
The differential diagnoses of kidney failure following cardiac catheterization includes ischemic acute tubular necrosis, cardiorenal syndrome, renal atheroemboli/cholesterol emboli syndrome, and prerenal causes of AKI.
Other distinguishing features of atheroembolic acute AKI are the presence of embolic lesions (as on the toes and fingers), livedo reticularis, transient eosinophilia, hypocomplementemia, vague abdominal pain (due to small vessel ischemic disease), and Hollenhorst plaques (cholesterol emboli to retinal vessels).
