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. [6]
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]
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]
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 ...
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 ...

Historically, it was commonly seen during pregnancy and in mothers who have just given birth. In cases of pregnancy, it is most often seen during the third trimester, resulting from a compression of the left common iliac vein against the pelvic rim by the enlarged uterus. Today, this disease is most commonly (40% of the time) related to some ...
