Gunshot and explosive projectile vascular injuries

The number of military and civilian gunshot and explosive projectile vascular injuries has increased in the past decades. In most conflicts, non-Geneva weapons are in use, with the majority of wounds made by high-velocity fragments and high velocity soft-point bullets. The initial mine or mortar fragment velocity has reached 2000 m/s. The doubling of missile velocity quadruples its kinetic energy and also the increase in mass augments the kinetic energy. Quadrupling of the projectile mass can have an eightfold increase in kinetic energy at the same velocity. Acting this way, the missile disperses a high quantity of the kinetic energy in the tissues, provoking the grinding effect. In addition to its direct effect, the bullet can damage the blood vessels with the high-velocity cavitational effect, resulting in stretching, disrupting, or thrombosis. The formation of a temporary cavity, however, is not a new phenomenon associated with modern high- velocity weapons.
