Query: Cerebrovascular injury caused by a high strain rate insult in the thorax   Primary blast-induced traumatic brain injury (TBI) has increased in
documented incidence and public prominence in recent conflicts. Evidence for a
thoracic mechanism of blast-induced TBI was recently reviewed and, while the
totality is compelling, data from experiments isolating this mechanism is
sparse. Notably, one recent study showed pericapillar haemorrhage in brain
tissue from victims of single, fatal gunshot wounds to the chest. Here,
qualitative results are reported for a small field study that isolated a
thoracic mechanism for TBI caused by a high strain rate insult in white-tailed
deer (Odocoileus virginianus, mass 49-80 kg) in a natural environment. In each
of three cases, petechiae were present on the surface of the frontal, occipital
and/or left parietal lobes, along with capillary damage in the choroid plexus.
The location of the projectile impact to the thorax seemed to affect the degree
of damage. This may be due to the proximity to the great vessels. The data
reported here provides direct evidence of a thoracic mechanism resulting in
gross injury to the cerebral vasculature.
