Arterial rupture is a breach of the integrity of the arterial wall. There are two types of occlusive arterial rupture and open arterial rupture. Closed arterial ruptures are common in emergency situations such as traffic accidents, high falls, crush injuries, and dissecting aneurysm ruptures; open arterial ruptures are common in stab wounds, bullet penetrating wounds, and blast injuries, and can cause death in a very short time. In such on-site emergency treatment, in order to stop the bleeding in the first place, pressure and ligation have to be used to block the arterial blood supply, which will also cause ischemia of the distal target organ and cause related serious complications.
