Section 1 Submit Findings Case217c Findings Low Neck Evaluation (Aorta, Brachiocephalic, Proximal Common Carotid (CCA) & Proximal Vertebral Arteries) There is evidence of aortic arch dissection or other abnormality. Yes No There is evidence of occlusion of brachiocephalic arteries. Yes No There is evidence of stenosis of brachiocephalic arteries. Yes No There is evidence of occlusion at the origin of a carotid artery. Yes No There is evidence of stenosis at the origin of a carotid artery. Yes No Given a CCA is occluded, are the vertebral to occipital branch of the external carotid artery (EAC) collateral arcades functional. Yes No There is evidence of occlusion in the proximal segment of a vertebral artery. Yes No There is evidence of stenosis in the proximal segment of either vertebral artery. Yes No Upper cervical neck & intracranial/extradural evaluation There is evidence of occlusion at the carotid bifurcation including proximal ICA or ECA or both. Yes No There is evidence of flow-limiting stenoses within either the high cervical carotid or the vertebral arteries, exceeding 60% or less by NASCET standards. Yes No There is dissection, pseudoaneurysm, or intimal web or both in the high cervical ICA's or vertebral arteries. Yes No There is intimal ulceration or intimal dehiscence in the area(s) of carotid plaque. Yes No There is intraluminal soft clot in the area of carotid plaque or pseudoaneurysm. Yes No There is large vessel vasculopathy (FMD) of high cervical or intracranial/extradural ICA or vertebral arteries. Yes No There is focal flow-limiting stenosis/occlusion of the ICA in its' intracranial-extradural segment. Yes No There is focal stenosis or occlusion of the ICA or the vertebral at the dural ring or within the intradural vertebral segment. Yes No There is evidence of reduced size of the either the high cervical carotid or vertebral arteries related to downstream stenosis Yes No There is functional EC-IC collateral with enlargement of the internal maxillary or middle meningeal arteries. Yes No There is increased size of either the ICA or vertebral arteries consistent with exaggerated intracranial flow demand (i.e. collateralization). Yes No There is is evidence of macrovasculopathy of the proximal intradural ICA with stenoses and or abnormal perforators (both lenticulostriate and/or thalamostriate) representing moyamoya collateralization (disease, syndrome or adult moyamoya forms). Yes No There is evidence of meningeal arteries connecting with pial arteries representing moyamoya collateralization. Yes No There is thrombosis of internal jugular or other large neck veins. Yes No There is thrombosis of the sigmoid, transverse, or torcular sinuses. Yes No Other No other abnormalities are noted. Yes No
