It passes behind the psoas major muscle, but in front of the lumbar vertebrae. [1] When the ascending lumbar vein crosses the subcostal vein, it becomes one of the following: the azygos vein (in the case of the right ascending lumbar vein). [1] [2] the hemiazygos vein (in the case of the left ascending lumbar vein). [1]
The 3rd and 4th lumbar veins drain into the inferior vena cava. [3]The fate of the two superior lumbar veins is far more variable, and may drain into either the inferior vena cava, ascending lumbar vein, azygos vein, or (on the left side) the left renal vein; the 1st lumbar vein often passes inferiorly to join the 2nd lumbar vein, but may less commonly drain into the ascending lumbar vein, or ...
Symptoms experienced by an individual with a paradoxical embolism can be from both the original site of thrombus and the location of where the emboli lodges. It is believed that the most common origin site of thrombus is from a deep vein thrombosis (DVT), however, in most patients with suspected paradoxical embolism no evidence of a DVT is ...

Jugular vein thrombosis is a condition that may occur due to infection, intravenous drug use or malignancy. Jugular vein thrombosis can have a varying list of complications, including: systemic sepsis, pulmonary embolism, and papilledema. Though characterized by a sharp pain at the site of the vein, it can prove difficult to diagnose, because ...
While venous thrombosis of the legs is the most common form, venous thrombosis may occur in other veins. These may have particular specific risk factors: [5] Cerebral venous sinus thrombosis, cavernous sinus thrombosis and jugular vein thrombosis: thrombosis of the veins of the brain and head
A venous embolus (mostly from deep vein thrombosis in the lower limbs) will travel through the systemic circulation, reach the right side of the heart, and travel through the pulmonary artery, resulting in a pulmonary embolism. Arterial thrombosis resulting from hypertension or atherosclerosis can become mobile and the resulting emboli can ...
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.
