Anatomical terminology

The internal iliac artery (formerly known as the hypogastric artery) is the main artery of the pelvis.

Structure

The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. The vesicular branches of the internal iliac arteries supply the bladder

It is a short, thick vessel, smaller than the external iliac artery, and about 3 to 4 cm in length.

Course

It arises at the bifurcation of the common iliac artery, opposite the lumbosacral articulation, and, passing downward to the upper margin of the greater sciatic foramen, divides into two large trunks, an anterior and a posterior.

The following are relations of the artery at various points: it is posterior to the ureter, anterior to the internal iliac vein, the lumbosacral trunk, and the piriformis muscle; near its origin, it is medial to the external iliac vein, which lies between it and the psoas major muscle; it is above the obturator nerve.

Branches

The exact arrangement of branches of the internal iliac artery is variable. Generally, the artery divides into an anterior division and a posterior division, with the posterior division giving rise to the superior gluteal, iliolumbar, and lateral sacral arteries. The rest usually arise from the anterior division.

The following are the branches of internal iliac artery. Because it is variable, a listed artery may not be a direct branch, but instead might arise off a direct branch.

Division	Branch	Sub-branches	To/through
Posterior	Iliolumbar artery	lumbar and iliac branches	psoas major muscle, quadratus lumborum muscle, iliacus muscle
Posterior	Lateral sacral artery	superior and inferior branches	anterior sacral foramina
Posterior	Superior gluteal artery	-	greater sciatic foramen
Anterior	Obturator artery (occasionally from inferior epigastric artery)	-	obturator canal
Anterior	Inferior gluteal artery	-	greater sciatic foramen
Anterior	Umbilical artery	Artery to vas deferens (male) and Superior vesical artery (usually, but sometimes it branches directly from anterior trunk)	medial umbilical ligament
Anterior	Uterine artery (female)	vaginal branch	uterus
Anterior	Vaginal artery (female) The artery usually takes the place of the inferior vesical artery present in the male	-	vagina and the base of the bladder
Anterior	Inferior vesical artery	-	urinary bladder
Anterior	Middle rectal artery	-	rectum
Anterior	Internal pudendal artery	many branches - see article for details	Greater sciatic foramen

Structure in fetus

In the fetus, the internal iliac artery is twice as large as the external iliac, and is the direct continuation of the common iliac.

It ascends along the side of the bladder, and runs upward on the back of the anterior wall of the abdomen to the umbilicus, converging toward its fellow of the opposite side.

Having passed through the umbilical opening, the two arteries, now termed umbilical, enter the umbilical cord, where they are coiled around the umbilical vein, and ultimately ramify in the placenta.

At birth, when the placental circulation ceases, the pelvic portion only of the umbilical artery remains patent gives rise to the superior vesical artery (or arteries) of the adult; the remainder of the vessel is converted into a solid fibrous cord, the medial umbilical ligament (otherwise known as the obliterated hypogastric artery) which extends from the pelvis to the umbilicus.

Variation

In two-thirds of a large number of cases, the length of the internal iliac varied between 2.25 and 3.4 cm.; in the remaining third it was more frequently longer than shorter, the maximum length being about 7 cm. the minimum about 1 cm.

The lengths of the common iliac and internal iliac arteries bear an inverse proportion to each other, the internal iliac artery being long when the common iliac is short, and vice versa.

The place of division of the internal iliac artery varies between the upper margin of the sacrum and the upper border of the greater sciatic foramen.

The right and left hypogastric arteries in a series of cases often differed in length, but neither seemed constantly to exceed the other.

Common branching variations

• The typical example

Collateral Circulation

The circulation after ligature of the internal iliac artery is carried on by the anastomoses of:

• the middle rectal artery (from the anterior division of the internal iliac artery) and the superior rectal artery (a branch of the inferior mesenteric artery)
• the iliolumbar artery (from the posterior division of the internal iliac artery) with the last lumbar artery (from the aorta)
• the lateral sacral arteries (from the posterior division of the internal iliac artery) with the median sacral artery (from the aorta)
