3. Fig 2
Representation of carotid duplex scan results for the 1,719 patients, arrayed by age and severity of carotid disease. Tight stenoses are seen in the younger strata, which reinforces that advanced age should not be the sole screening criterion.

Distribution of perioperative strokes by cause. In many previous series carotid artery stroke accounted for up to a third of perioperative strokes.

5. Fig 4
Distribution by age of patients who had combined carotid and cardiac operations. Despite the age screening criterion (≥ 65 years), inclusion of left main coronary artery disease and previous central nervous system criteria led to detection of significant stenoses in the younger patients.

Algorithm demonstrating elimination of risk of carotid artery stroke with aggressive detection and treatment. Inclusion of carotid endarterectomy (CEA) for patients with carotid stenoses greater than 80% significantly reduced the risk for carotid type stroke (CVA) (p = ; odds ratio, 20.2).
