common iliac vein

The vein accompanying the common iliac artery; it is formed by the union of the external and internal iliac veins, and it ends by merging with the opposite common iliac vein to form the inferior vena cava. The right iliac vein is shorter than the left. Tributaries of the common iliac vein include the iliolumbar, lateral sacral, and median sacral veins.

Treatment modalities include use of anticoagulant, catheter directed thrombolysis, stent placement, placement of filters, surgical approaches including vein patch angioplasty with excision of intraluminal bands, division of the right common iliac artery and relocation behind the left common iliac vein or inferior vena cava and saphenous vein graft bypass to the inferior vena cava or ipsilateral common femoral vein.2 Reestablishment of vessel patency by removing the thrombus, relieving the acute symptoms in order to prevent recurrent thrombosis and pulmonary embolism and to reserve venous valve function, thus preventing post-thrombotic syndrome is the main purpose of treatment for postpartum DVT.

The median sacral vein is an unpaired vein located at the medial aspect of the sacrum and accompanies the middle sacral artery to receive blood from the sacral venous plexus, emptying into the left common iliac vein. The median sacral vein was considered dilated when its diameter measured [greater than or equal to] 2 mm [9].
