| Deep circumflex iliac vein | |
| Latin: | vena circumflexa ilium profunda |
| Drainsto: | External iliac vein |
| Artery: | Deep circumflex iliac artery |
The deep circumflex iliac vein is formed by the union of the venae comitantes of the deep iliac circumflex artery.[1] It drains venous blood from the walls of the iliac fossa.[2] It empties into the external iliac vein about 2 cm superior to the inguinal ligament,[3] just distal to where the inferior epigastric vein does so. The DCIV runs across the external iliac artery. It forms anastomoses with the iliolumbar vein, and lower two lumbar veins.
