internal iliac vein

The uterine veins are tributaries of the internal iliac veins.

The posterior lymph sacs are associated with the junctions of the external and internal iliac veins.

The middle part of the external plexus is drained by the middle rectal vein which joins the internal iliac vein.

In front of it are the internal iliac artery, internal iliac vein, the ureter, and the sigmoid colon.

Internal iliac vein - terminates at the common iliac vein, drains pelvic organs and perineum.

They run lateralward on the pelvic surface of the levator ani to end in the internal iliac vein.

The most prominent of these is a laceration of the left internal iliac vein which lies in close proximity to the anterior portion of the disc.

In human anatomy, the common iliac veins are formed by the external iliac veins and internal iliac veins.

Common iliac vein - formed by the external and internal iliac veins, drains into the inferior vena cava.

Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins).

The lymphatic drainage of the cervix is along the uterine arteries and cardinal ligaments to the parametrial, external iliac vein, internal iliac vein, and obturator and presacral lymph nodes.

The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the Internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.

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 joins the common iliac vein, the tributaries of the Internal Iliac vein correspond with the branches of the Internal iliac artery.
