👉 Tubulation is a medical condition characterized by the presence of blood clots in the veins. It occurs when blood vessels become narrowed or blocked, leading to the formation of blood clots that can cause significant damage to the blood vessels and organs, including the heart, lungs, and brain. Tubulation is usually caused by a variety of factors, such as trauma, infection, and certain medications. Treatment for tubulation typically involves the removal of the blood clot or other obstruction.
