Appendicular vein

Appendicular Vein

The appendicular vein, shown in red, is a blood vessel that drains the appendix into the ileocolic vein.

The appendicular vein is a blood vessel that drains the appendix into the ileocolic vein. It is a part of the venous system of the digestive system and plays a crucial role in the removal of deoxygenated blood from the appendix.

Structure

The appendicular vein begins at the tip of the appendix and follows the course of the appendicular artery in the opposite direction. It drains into the ileocolic vein, which is a branch of the superior mesenteric vein. The appendicular vein is typically located within the mesoappendix, a fold of the peritoneum that connects the appendix to the ileum and contains the appendicular artery and vein.

Function

The primary function of the appendicular vein is to drain deoxygenated blood from the appendix and deliver it to the ileocolic vein. This process is a part of the larger venous drainage system of the digestive system, which ultimately returns blood to the heart via the inferior vena cava.

Clinical significance

Understanding the anatomy of the appendicular vein is important in the context of appendicitis, a common condition that can lead to severe complications if not treated promptly. In cases of appendicitis, inflammation can cause the appendicular vein to become blocked, leading to increased pressure and potential rupture of the appendix.
