: values are statistically significant compared to preintervention. vessel grading is a system used to quantify the size of the collateral vessels formed as follows: Grade 0: no collateral vessels. Grade 1: ≤5 small. Grade 2: >5 small. Grade 3: ≤5 large ± small. Grade 4: >5 large ± small. vessel category is a system used to quantify the number of collateral vessels present as follows: Category 0: no collateral vessels. Category 1: 1–3 collateral vessels. Category 2: 4–7 collateral vessels. Category 3: ≥8 collateral vessels.
