The internal rectal venous plexus is a network of veins located inside the rectum, the last part of the digestive system. These veins play a crucial role in draining blood from the rectum back to the heart. When cancer develops in or near this venous plexus, it can lead to serious health issues, often associated with colorectal or rectal cancer.
Anatomy of the Internal Rectal Venous Plexus
Structure
- The internal rectal venous plexus consists of small veins located in the wall of the rectum. It forms part of the hemorrhoidal veins and contributes to the hemorrhoidal cushions, which help control stool passage.
Blood Supply
- Blood is supplied to this plexus by the superior, middle, and inferior rectal arteries. These veins drain blood from the rectum and transport it to the heart through the portal venous system.
Nerve Supply
- The nerves in the rectum and internal venous plexus are supplied by the autonomic nervous system, which controls involuntary actions such as blood flow and muscle contraction.
Types of Rectal Plexus Cancer
- Primary Cancer: This cancer originates in the rectum and involves the venous plexus.
- Metastatic Cancer: This occurs when cancer from another part of the body spreads to the rectal venous plexus.
Causes of Rectal Venous Plexus Cancer
While cancer in the rectal venous plexus is often part of colorectal cancer, here are potential causes:
- Genetic Mutations – Changes in the DNA of rectal cells.
- Family History – A history of colorectal cancer in the family.
