Internal carotid artery occlusion
Conditions
Interventions
Gold Standard:The ophthalmic artery collateral status (OACS) was divided into three grades by DSA: Grade 0 - no or slight collateral compensation (no or slight contrast filling of OA)
Grade 1 - small but definite collateral compensation (retrograde contrast flow in OA with filling of carotid siphon segment)
Grade 2 - good collateral compensation (retrograde contrast flow to the middle cerebral artery (MCA) and anterior cerebral artery (ACA)). Grade 0-1 was defined as poor OACS group, and grade 2 was defi
Index test:Facial thermal imaging asymmetry index
