Table 1: Clinical and imaging features of 7 patients with occluded internal carotid artery and acute stroke
Patient No./Age (y)/Sex Site of Occlusion (CTA) Presence of Penumbra (CTP) NIHSS at Presentation NIHSS at Follow-up
1/54/M LICA and LMCA: M1 Yes 22 15 (1 mo)
2/51/M LICA and LMCA: M1 and M2 Yes 15 1 (14 mo)
3/62/F RICA and RMCA: M1 Yes 21 0 (6 mo)
4/78/F LICA and LMCA: M1 Yes 11 0 (5 mo)
5/70/F RICA^* Yes^† 17 1 (14 mo)
6/28/F LICA and LMCA: M1 No perfusion study^‡ 17 0 (40 mo)
7/24/M RICA and RMCA: M1 No perfusion study 12 0 (1 mo)
Note:—CTA indicates computed tomographic angiography; CTP, computed tomographic perfusion; NIHSS, National Institutes of Health Stroke Scale; RICA, right internal carotid artery; LICA, left internal carotid artery; RMCA, right middle cerebral artery; LMCA, left middle cerebral artery.
* Seen on MR angiogram.
† Seen on MR perfusion study.
‡ No perfusion imaging performed since the intervention “pre-dated routine perfusion imaging.”
