From: An excess vessel in the posterior part of the human cerebral arterial circle (CAC): a case series
Adult cases | Relations of arteries |
|---|---|
Case 1. | Left PCA-P1b > left ICoA ≈ left PCA-P1c ≈ right P1 < right PCoA |
Case 2. | Right ICoA < right PCA-P1c < right PCA-P1b ≈ left PCoA > left P1 |
Case 3. | Left PCoA ≈ right ICoA < right PCA-P1b < right PCA-P1c < left P1 |
Case 4. | Right PCA-P1c ≈ right ICoA< right PCA-P1b ≈ left P1 > left PCoA |
