| Right | 35 (60.3) | 17 (65.4) | 0.660 |
| Extension of CCA dissection | |||
| Proximal CCA | 14 (24.1) | 5 (19.2) | 0.619 |
| Whole CCA | 41 (70.7) | 15 (57.7) | 0.243 |

| Detailed findings of CCA dissection | |||
| With re-entry | |||
| Same enhancement in the true and false lumen | 29 (50.0) | 5 (19.2) | 0.008 |

| No re-entry | |||
| Without severe narrow in the true lumen | 23 (39.7) | 2 (7.7) | 0.003 |
| Severely narrowed true lumen by thrombosed false lumen | 4 (6.9) | 8 (30.8) | 0.005 |
Note.-The data are numbers of patients, with percentages in parentheses.
NND = no neurological dysfunction; TND = temporary neurological dysfunction; CCA = common carotid artery; ICA = internal carotid artery.
