In this study, the available evidence supporting shunting, nonshunting, and selective shunting during CEA were analyzed.

Methods
An electronic PubMed/MEDLINE search was conducted
Identify all published CEA studies between January1990 and December 2010, that analyzed the perioperative outcome of routine shunting, routine nonshunting, and selective shunting based on EEG,TCD, SP, CBA, and SSEP.

Results:
The mean reported perioperative stroke rate for CEAs with routine shunting was 1.4%.
Routine nonshunt was 2%. The mean perioperative stroke rates
for selecting shunting were 1.6% using EEG, 4.8% using TCD,1.6%
using SP, 1.8% using SSEP, and 1.1% for CBA.

Analysis of Complication
• Was the complication potentially avoidable?– YES, IF SHUNTING WAS ESTABLISHED
• Would avoiding the complication change the outcome for the patient?– YES
• What factors contributed the complication?• Stroke likely related to hypoperfusion due to inability to
put a shunt and likely poor collateral circulation.
