Anatomy of the External Rectal Venous Plexus

Structure

The external rectal venous plexus is a network of veins located around the rectum, the final part of the large intestine. These veins play a role in draining blood from the rectal area back to the heart. When an abnormal connection, called a fistula, forms between these veins, it can disrupt normal blood flow and cause various issues.

Blood Supply

Blood in the rectal area is supplied by arteries that branch from the inferior rectal arteries. The venous plexus collects this blood, and any blockage or abnormal connections can lead to swelling, pain, or bleeding.

Nerve Supply

The rectal area is innervated by nerves that control sensations and muscle movements. These nerves can be affected by a fistula, leading to discomfort or changes in bowel habits.

Types of External Rectal Venous Plexus Fistulas

Fistulas in the external rectal venous plexus can vary based on their location, size, and the severity of symptoms. Common types include:

1. Low-Flow Fistulas: Small connections with minimal symptoms.
2. High-Flow Fistulas: Larger connections causing significant symptoms like pain and bleeding.
3. Congenital Fistulas: Present from birth due to developmental issues.
4. Acquired Fistulas: Develop later in life due to injury, surgery, or disease.
