A Suicide Attempt with a Velo-Dog Pocket Revolver in an Alleged Victim of Carjacking

In hospital emergencies, we can have the most picturesque and impressive cases, from the simplest to the most complex. Violence cases are not rare, and among these are the injuries caused by firearms, which may vary in severity depending on the affected region and the energy of the projectile. Head injuries are generally very serious, and it is rare the individuals survival without sequelae. This work reports a 38-year-old man who was admitted to the emergency room alone in the morning, walking, lucid, and oriented, mentioning that the night before he was in the car and that he had been shot in the head in an attempt at carjacking. On examination, he had only one entry wound in the right temporal region, and the history revealed a suicide attempt with a very rare firearm: a Velo-Dog. We hypothesized that the low-density energy of this revolver, which historically used to be carried by cyclists as a defense against dog attacks, may partially explains the non-skull penetration.
