Ligature strangulation is a form of asphyxia that occurs when a constricting device, such as a rope or cord, is tightened around the neck. This pressure restricts blood flow and airflow, leading to unconsciousness or death if not quickly relieved. It is often associated with cases of homicide, suicide, or accidental deaths. The ligature used in strangulation can vary widely, including items like belts, shoelaces, or any flexible material. The effects of ligature strangulation can be severe, causing damage to the trachea, blood vessels, and nervous system, and may leave visible marks on the skin.
