| Synonyms: | ISV |
| Definition: | Veins that connect the posterior cardinal vein and the dorsal longitudinal anastomotic vessel. They run along the vertical myotomal boundaries. They form from primary intersegmental vessels that are contacted by secondary angiogenic sprouts from the posterior cardinal vein and take on the characteristics of veins. These eventually link with other secondary sprouts from the posterior cardinal vein to form the parachordal vessel. |
