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.

Inferior vena cava syndrome (IVCS) is a very rare constellation of symptoms resulting from either obstruction or stenosis of the inferior vena cava. It can be caused by physical invasion or compression by a pathological process, or by thrombosis within the vein itself. It can also occur during pregnancy. Symptoms including high venous pressure ...
Most cases of CVI can be improved with treatments to the superficial venous system or stenting the deep system. Varicose veins for example can now be treated by local anesthetic endovenous surgery. Rates of CVI are higher in women than in men. [4] [5] Other risk factors include genetics, smoking, obesity, pregnancy, and prolonged standing. [6]
Risk factors, present in around 50% of documented cases, include malignancy, hyper-coagulable states, cardiac disease, venous stasis, venous insufficiency, May-Thurner syndrome (right iliac artery compressing the left iliac vein that runs beneath it), surgery, trauma, pregnancy, inferior vena cava (IVC) filter, hormone therapy, oral contraceptives, prolonged immobilization, inflammatory bowel ...
Treatment involves revascularization typically using either angioplasty or a type of vascular bypass [citation needed] Kissing balloon angioplasty +/- stent, so named because the two common iliac stents touch each other in the distal aorta. Aorto-iliac bypass graft; Axillary-bi-femoral [3] [4] and femoral-femoral bypass (sometimes abbreviated ...
Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [1] [7] The condition may cause chronic pain, such as a constant dull ache, which can be worsened by standing or sex. [1]

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 ...
