| Location | typical | with common trunk | with common antrum | with ostial branch | with supernumerary vein (MPV) |
|---|---|---|---|---|---|
| LSPV | 23(38.3) | 11(18.3) | 25(41.7) | 2(3.3) | 0 |
| LIPV | 23(38.3) | 11(18.3) | 25(41.7) | 3(5.0) | 0 |
| RIPV | 24(40) | 0 | 6(10) | 27(45) | 4(6.7) |
| RSPV | 37(61.7) | 0 | 6(10) | 14(23.3) | 4(6.7) |
| Total | 107(44.6) | 22(9.2) | 62(25.8) | 46(19.2) | 8(3.3) |
Values are n (%). MPV: middle pulmonary vein; LSPV: left superior pulmonary vein; LSPV: left superior pulmonary vein; LIPV: left inferior pulmonary vein; RIPV: right inferior pulmonary vein; RSPV: right superior pulmonary vein.
