The vena cava is to the right of the midline and therefore the left common iliac vein is longer than the right. [2] The left common iliac vein occasionally travels upwards to the left of the aorta to the level of the kidney , where it receives the left renal vein and crosses in front of the aorta to join the inferior vena cava. [ 4 ]
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet.

Compression of the left external iliac vein by the right common iliac artery or left hypogastric artery can occur as it crosses over the vein into the pelvis. The right external iliac vein can similarly be compressed. Such compressions may contribute to deep vein thrombosis. [5] Failure to develop or agenesis of the external iliac vein has been ...
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]
In human anatomy, iliac vein refers to several anatomical structures located in the pelvis: Common iliac vein, formed by the external and internal iliac veins, drains into the inferior vena cava; Deep circumflex iliac vein, formed by the union of the venae comitantes of the deep iliac circumflex artery, and joins the external iliac vein
It also joins with the azygos vein (which runs on the right side of the vertebral column) and venous plexuses next to the spinal cord. The inferior vena cava begins as the left and right common iliac veins behind the abdomen unite, at about the level of L5. [1] [2] It passes through the thoracic diaphragm at the caval opening at the level of T8 ...
The right common iliac artery passes in front of the left common iliac vein. In some individuals, mainly women with lumbar lordosis , this vein can be compressed between the vertebra and the artery. This is the so-called Cockett syndrome or May–Thurner syndrome [ 2 ] can cause a slower venous flow and the possibility of deep venous thrombosis ...
