Both common iliac arteries are accompanied along their course by the two common iliac veins, which lie posteriorly and to the right. Their terminal bifurcation is crossed anteriorly by the ureters. [1] This is significant, as the bifurcation of the common iliac artery is the second point of ureteric constriction. [1]
The ureters are tubular structures, approximately 20–30 cm (8–12 in) in adults, [1] that pass from the pelvis of each kidney into the bladder. From the renal pelvis, they descend on top of the psoas major muscle to reach the brim of the pelvis. Here, they cross in front of the common iliac arteries.

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.
In human anatomy, the common iliac veins are formed by the external iliac veins and internal iliac veins. The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, [1] forming the inferior vena cava. They drain blood from the pelvis and lower limbs. Both common iliac veins are accompanied ...
The external iliac vein is crossed by the ureter and internal iliac artery which both extend towards the middle. In males it is crossed by the vas deferens and in females the round ligament and ovarian vessels cross it. Psoas major lies to its side, except where the artery intervenes. [4] The external iliac vein may have one valve, but often ...

In human anatomy, the iliac arteries are three arteries located in the region of the ilium in the pelvis: . Common iliac artery – forms at terminus of the aorta; External iliac artery – forms where the common iliac artery bifurcates, continues as the femoral artery at the inguinal ligament
