Comparing outcomes of carotid endarterectomy with international benchmarks: audit from an Italian vascular surgery department.

Background: The aim of this study was to compare the outcomes of carotid endarterectomy (CEA) in the current practice of our department of vascular surgery with international benchmarks.

Methods: In-patient data from 488 CEA performed in both symptomatic 145 (29.7%) and asymptomatic 343 (70.3%) patients with a > or = 60% stenosis at the level of the internal carotid artery. Comprehensive retrospective review of the records for all the CEAs performed during a 2-year period. The main outcome measures were death rate, and fatal and non-fatal stroke rates perioperatively, and at 30 and 180 days.

Results: The fatal and non-fatal stroke rates of symptomatic patients were: 0.7% perioperatively, 0.7% at 30 days, and 0.7% at 180 days. The fatal and non-fatal stroke rates of asymptomatic patients were: 0.6% perioperatively, 0.6% at 30 days, and 0.3% at 180 days. The death rates of symptomatic patients were 0% for all time periods. The death rates of asymptomatic patients were: 0% perioperatively, 0% at 30 days, and 0.3% at 180 days.

Conclusions: The present comprehensive audit shows that our surgeons achieve CEA outcomes comparable with international benchmarks.
