If both of the carotid arteries were destroyed, while hydrostatic shock may have been present, it is not likely that a pressure wave started in a small vessel (compared to a heart chamber) would be devastating. Instead, near the head on the carotids are pressure sensors called baroreceptors. It is their job to try to regulate blood pressure. In the event of sudden pressure drop, an instant attempt to correct will occur. When all else fails, since the head is critical, the animal may drop or essentially pass out . This is a last ditch effort to improve blood flow to the brain by lowering the head to a point at or below the body. It is reflex controlled. If I'm not quite correct on this, please let me know...school was a long time ago.
