Impact of chronic renal insufficiency using serum creatinine vs glomerular filtration rate on perioperative clinical outcomes of carotid endarterectomy.

Background: Several studies have reported conflicting results after carotid endarterectomy in patients with chronic renal insufficiency (CRI). However, only a few used glomerular filtration rate (GFR) (Modification of Diet in Renal Disease) in their analysis.

Study Design: Nine hundred and forty carotid endarterectomies that had serum creatinine and GFR were analyzed.
