Thoracoepigastric vein
Thoracoepigastric vein
The Thoracoepigastric vein (pronunciation: tho·ra·co·epi·gas·tric vein) is a superficial vein that plays a significant role in the human circulatory system.
Etymology
The term "Thoracoepigastric" is derived from two Greek words: "thorax" meaning chest, and "epigastrium" meaning the upper central region of the abdomen.
Anatomy
The Thoracoepigastric vein is a long, slender vein that runs vertically along the lateral aspect of the trunk. It connects the superficial epigastric vein, which drains the anterior abdominal wall, with the lateral thoracic vein, which drains the lateral aspect of the thorax.
Function
The primary function of the Thoracoepigastric vein is to facilitate the drainage of blood from the anterior abdominal and thoracic walls to the systemic venous system. It serves as an important collateral pathway when there is obstruction in the inferior vena cava or superior vena cava.
Clinical Significance
The Thoracoepigastric vein can become prominent in cases of superior or inferior vena cava obstruction, serving as a collateral pathway for blood return to the heart. It is also of clinical importance in certain surgical procedures, such as breast reconstruction surgery, where it may be ligated to prevent complications.
