Editing Hydrostatic shock (section)

==Autopsy findings==
Proponents of the concept point to human autopsy results demonstrating brain [[hemorrhaging]] from fatal hits to the chest, including cases with handgun bullets.<ref>Krajsa, J. Příčiny vzniku perikapilárních hemoragií v mozku při střelných poraněních (Causes of pericapillar brain haemorrhages accompanying gunshot wounds), Institute of Forensic Medicine, Faculty of Medicine, Masaryk University, Brno, Czech Republic, 2009.</ref> Thirty-three cases of fatal penetrating chest wounds by a single bullet were selected from a much larger set by excluding all other traumatic factors, including past history.
{{blockquote|In such meticulously selected cases brain tissue was examined histologically; samples were taken from brain hemispheres, basal ganglia, the pons, the oblongate and from the cerebellum. Cufflike pattern hemorrhages around small brain vessels were found in all specimens. These hemorrhages are caused by sudden changes of the intravascular blood pressure as a result of a compression of intrathoracic great vessels by a shock wave caused by a penetrating bullet.|J.

An 8-month study in Iraq performed in 2010 and published in 2011 reports on autopsies of 30 gunshot victims struck with high-velocity (greater than 2500 fps) rifle bullets.<ref name="Iraq" /> The authors determined that the lungs and chest are the most susceptible to distant wounding, followed by the abdomen. The study noted that the "sample size was so small [too small] to reach the level of statistical significance". Nevertheless, the authors conclude:
{{blockquote|Distant injuries away from the main track in high-velocity missile injuries are very important and almost always present in all cases, especially in the chest and abdomen and this should be put in the consideration on the part of the forensic pathologist
and probably the general surgeon.|R. S. Selman et al.<ref name="Iraq"/>}}
