Veins Anal

Anal veins (lat. vena anales) are a system of vessels that provide blood supply to the anal canal and rectum area. They are a continuation of the femoral and caval iliac veins, and begin from the posterior wall of the rectum below the point where the superior hemorrhoidal artery enters it.

The number of anal veins can vary between individuals. They are usually represented by four main branches:

The internal pudendal vein begins at the head of the penis and enters the body of the penis. Venous blood from this line flows into the femoral vein. Pyriform vein - located between the two lower gluteal openings and communicates with the straight vein in the sacral region. Blood from the piriformis vein mixes with blood from the femoral vein in the branches of the lumbar and abdominal parts of the aorta. The inferior cystic vein passes from the side of the body between the muscular layer of the base of the peritoneum and the prostatic part of the urethra. Cystic blood flows from the genitals and is transmitted to the right sections of the great inferior vein. The genital vein is a bridge between the external genitalia and the superior genital vein. Through this short vein, blood flows into the large genital vein, located inside the pelvis. The anal veins may be involved in pathological processes. For example, varicose veins in chronic venous insufficiency or vein thrombosis, which can occur as a result of traumatic brain injury, inflammatory processes in the body, intense physical activity or pregnancy. Identification of diseases of this coronary system and assessment of its condition should be carried out by a coloproctologist during a routine examination. Preventative measures include regular examinations, recommendations for physical activity and nutrition, and avoidance of heavy exercise and hypothermia.
