Overview
Definition
A stenosis os classified as having irregular contour if the vascular margin is rough or had a "sawtooth" appearance.[1]
Pathophysiology
Grading of Lesion Irregularity
- Grade 0: Smooth – no irregularity.
- Grade 1: Mildly Irregular – lesion has an indistinct lumen edge.
- Grade 2: Sawtoothed/Grossly Irregular – lesion has defined jagged or “sawtoothed” lumen edges.
Clinical Significance
Example
