(Redirected from Hemorrhoidal veins)
Rectal Vein
The Rectal Vein is a part of the human circulatory system that drains blood from the rectum, a part of the digestive system. It is a significant component of the portal venous system, which carries blood from the gastrointestinal tract and spleen to the liver.
Anatomy[edit | edit source]
The rectal vein is divided into three main veins: the superior, middle, and inferior rectal veins.
- The Superior Rectal Vein is the continuation of the inferior mesenteric vein, and it drains into the portal vein.
- The Middle Rectal Vein drains into the internal iliac vein.
- The Inferior Rectal Vein drains into the internal pudendal vein, which is a branch of the internal iliac vein.
Clinical Significance[edit | edit source]
The rectal veins are clinically significant as they can be involved in the development of hemorrhoids, a common condition characterized by swollen and inflamed veins in the rectum and anus.
