Detailed demographic and imaging/clinical features, including work-up, of patients with positive carotid webs in the cryptogenic stroke population^{^a}

Patient No.	Ethnicity	Stroke Location	Thrombus Location	Web Location	Work-Up Methods^{^b}	Management after Initial Event	Recurrent Stroke
1	White	Near complete right MCA territory infarction	Right M1	Bilateral	1–3^{^c}	Supportive care	No
2	African American	Near complete right MCA territory infarction	Right M1	Right	1–3^{^c}	Clot retrieval	No
3	African American	Right basal ganglia and temporal lobe infarcts	Right distal M1/proximal M2	Right	1–3	Supportive care	No
4	African American	Near complete left MCA territory infarction	Left distal M1/proximal M2	Bilateral	1–3	Supportive care	Yes, multiple recurrent
5	African American	Near complete left MCA territory infarction	Left M1	Bilateral	1–3^{^c}	Clot retrieval, then CEA	N/A
6	African American	Left basal ganglia and insular cortex infarcts	Left M2	Left	1–3	Supportive care, then CEA	N/A
7	African American	Left basal ganglia and insular cortex infarcts	Left M2	Left	1–3	Supportive care	No

Note:—CEA indicates carotid endarterectomy; M1, segment from the origin to the bifurcation/trifurcation of the MCA; M2, segment from the MCA bifurcation/trifurcation to the insular circular sulcus; N/A, no follow-up available.
↵a Patient ages ranged from 30–48 years, composed of 6 women and 1 man.
↵b Work-up of patients with carotid web: 1, echocardiogram; 2, cardiac telemetry; 3, cross-sectional head/neck vascular imaging.
↵c Interventional head/neck angiogram also performed.
