Arkadiusz Migdalski, Arkadiusz Jawień
Acta Angiologica 2008;14(2):66-71.


The duplex scan is the main tool used to diagnose carotid artery stenosis, and there is agreement that it might be the single preoperative diagnostic test.

The authors describe the pitfalls of the duplex scan examination in a symptomatic patient with bilateral severe distal internal carotid artery stenosis.
