The thoracoepigastric vein provides a communication between the superficial epigastric vein and the lateral thoracic vein as it ascends superficially on the anterolateral chest and abdominal wall. It, therefore, drains into both the superior vena cava (SVC) ~~via~~ via the axillary vein and the inferior vena cava(IVC) via the femoral vein. ~~It is often present in healthy individuals and in others may only become present in the setting of altered venous flow.~~

Related pathology

~~In the event of~~

in IVC obstruction, the thoracoepigastric vein ~~can~~may provide a collateral ~~circuit to~~ venous flow~~. Similarly, during~~
in portal hypertension, the paraumbilical veins may ~~communicate with~~form a portosystemic shunt with the thoracoepigastric vein ~~thus providing a~~ ~~portosystemic circuit~~.
~~Inflammation~~
inflammation of the thoracoepigastric ~~vein and~~(and surrounding) veins is known as Mondor disease.
