FIG 2. Angiographic and DWI findings in four patients in group CA. A/M = watershed area between the ACA and MCA, Lt. = left, Rt. = right, gray circle = carotid stenotic lesion or complicated lesion in the arch; black circle = culprit lesion; asterisk = cross-flow, intracranial cross-flow through the AcoA from the predominantly affected side to the contralateral side; double asterisk = right MCA area, which was supplied by the left ICA through the AcoA because the right ICA was completely occluded at the origin; and triple asterisk = aortic lesion, which remains unknown because of the lack of transesophageal echocardiography.
