Iliac vein compression syndrome

Iliac venous compression syndrome (iliac venous compression syndrome) is a disorder of lower limb and pelvic venous reflux caused by compression of the iliac vein and / or the presence of abnormal intraluminal adhesion structures. In 1965, Cockett and Lea Thomas used venography and surgery to study patients with a history of iliac-femoral vein thrombosis and severe thrombotic sequelae. It was found that in the area where the right common iliac artery crosses the left common iliac vein, the vein is prone to thrombosis. And the formed thrombus is difficult to reopen, which causes venous reflux disorders of the lower limbs and pelvis, resulting in a series of clinical symptoms and signs. So some people call this syndrome Cockett syndrome. Compression of the iliac vein not only causes venous reflux disorders and venous hypertension in the lower limbs, it is one of the causes of venous insufficiency of the lower limbs and superficial varicose veins, but it can also cause secondary iliac-femoral vein thrombosis, which is a potential factor for venous thrombosis to occur in the left lower limb .
