Atherosclerosis not detected. Ruling out atherosclerosis: (1) extracranial arterial stenosis: one or several of the following diagnostic tests are performed and are negative: US-Duplex,CTA, MRA, XRA, or autopsy, (2) intracranial arterial stenosis: one or several of the following diagnostic tests are performed and are negative: US-TCD,MRA, CTA, XRA, or autopsy, (3) aortic arch atheroma: TEE with specific assessment of the aortic arch (when the probe is pulled back at the end of the cardiac examination, turn the probe counter clockwise and take time to watch the aortic arch) or specific aortic arch assessment with CTA

Potentially causal. Atherothrombotic stroke defined as: (1) ipsilateral atherosclerotic stenosis between 50 and 99% in an intra- or extracranial artery supplying the ischemic field, or (2) ipsilateral atherosclerotic stenosis

Causal link is uncertain. (1) ipsilateral atherosclerotic stenosis 30-50% in an intra- or extracranial artery supplying the ischemic field, or (2) aortic plaque =4 mm without mobile lesion

Causal link is unlikely, but the disease is present. (1) plaque (stenosis <30%) in an intra- or extracranial artery, ipsilateral to the infarct area, (2) aortic plaque <4 mm without mobile thrombus, (3) stenosis (any degree) or occlusion in a cerebral artery not supplying the infarct area (e.g. contralateral side or opposite circulation), (4) history of myocardial infarction, coronary revascularization or peripheral arterial disease, (5) ipsi- or bilateral atherosclerotic stenosis 50–99% with bihemispheric MR-DWI lesion

Incomplete workup. US-Duplex, US-TCD or CTA, or MRA, or XRA or autopsy not performed. [A minimum workup is extra- and intracranial assessment of cerebral arteries – maximum workup also includes transesophageal assessment of the aortic arch (or a default CTA of the aortic arch)]
