Carotid Artery Tandem Lesions Frequency and Consequences for Endarterectomy

We determined the frequency of tandem carotid lesions within the carotid siphon, common carotid artery and proximal intracerebral arteries as well as incidental intracranial saccular aneurysms. We also determined the consequence of a tandem lesion on the surgeon's decision-making process when a hemodynamically significant stenosis or aneurysm was detected during the preoperative evaluation.
