)y the union of the vense comitantes of the inferior epigastric artery, which com- 

 municate above with the superior epigastric vein; it joins the external iliac about 

 1.25 cm. above the inguinal ligament. 



The Deep Iliac Circumflex Vein (v. circumflexa ilium profunda) is formed by the 

 union of the vense comitantes of the deep iliac circumflex artery, and joins the 

 external iliac vein about 2 cm. above the inguinal ligament. 



The Pubic Vein communicates with the obturator vein in the obturator foramen, 

 and ascends on the back of the pubis to the external iliac vein. 



The hypogastric vein (v. hypogastrica; internal iliac vein) begins near the upper 

 part of the greater sciatic foramen, passes upward behind and slightly medial to 

 the hypogastric artery and, at the brim of the pelvis, joins with the external iliac 

 to form the common iliac vein.

Tributaries. With the exception of the fetal umbilical vein which passes upward 

 and backward from the umbilicus to the liver, and the iliolumbar vein which usually 

 ]oins the common iliac vein, the tributaries of the hypogastric vein correspond 

 with the branches of the hypogastric artery. It receives (a) the gluteal, internal 

 pudendal, and obturator veins, which have their origins outside the pelvis; (6) the 

 lateral sacral veins, which lie in front of the sacrum; and (c) the middle hemorrhoidal, 

 vesical, uterine, and vaginal veins, which originate in venous plexuses connected 

 with the. pelvic viscera.
