The termination points of the lateral direct veina
| Branching Type | LDV Termination | Total (110 LDV) | |
|---|---|---|---|
| Type 2 (a suprathalamic LDV) | ICV: anterior third | 8 | 7.27% |
| ICV: middle third | 70 | 63.64% | |
| ICV: middle third, as a common stem with an MAV | 2 | 1.82% | |
| Type 3 (a retrothalamic LDV) | ICV: posterior third | 18 | 16.36% |
| ICV: posterior third, as a common stem with an MAV | 8 | 7.27% | |
| Great cerebral vein | 2 | 1.82% | |
Note:—MAV indicates medial atrial vein.
↵a The presence of the LDV characterizes types 2 and 3 of the ICV branching patterns.
