Classification of carotid ulcerations based on morphology | |
|---|---|
Type 1 | Ulcer projecting perpendicular to the vessel’s lumen with parallel sides (1a) or sides converging to a point (1b) |
Type 2 | Narrow-necked ulcer (“mushroom shaped”) or an ulcer with no neck visible |
Type 3 | Ulcer with a proximal neck and its main part pointing distally, parallel to blood flow direction |
Type 4 | Ulcer with distal neck and its main part pointing proximally, opposite to blood flow direction |
