I86: Varicose veins of other sites

Varicose veins of other sites refer to a group of conditions characterized by the enlargement, elongation, and tortuosity of veins in locations other than lower extremities, usually found in legs. The site of these varicose veins may include esophagus, pelvis, uterus, and others. This condition occurs when the valves within the veins do not function properly, leading to blood pooling and applying pressure on the vein walls causing them to become weak, enlarged, and twisted. Symptoms can vary depending on the location but may include visible veins, a sensation of heaviness, swelling, and discomfort in the affected area. Over time, the conditions may progress and symptoms may worsen if not treated. Various organs or systems in the body can be affected, creating complications, including the circulatory system due to impaired blood flow.
