During predatory attacks, leopards typically bite their prey's throat or the nape of the neck, lacerating or severing jugular veins and carotid arteries, causing rapid exsanguination.
Patients can also develop catastrophic internal hemorrhages, such as from a bleeding peptic ulcer, postpartum bleeding or splenic hemorrhage, which can cause exsanguination without any external signs of distress.
The technique usually involves exsanguination, which forces blood out of the extremity, followed by the application of pneumatic tourniquets to safely stop blood flow.
