Results of this study will be the basis for future investigation of CACs according to the same or different ages and causes of disease and/or death.

The authors describe 3 cases of lethal injuries caused by 7.62 mm blank cartridge shots from military automatic rifle of domestic origin (AK 47, 7.62 mm). In 1 case, the cartridge was fired from a weapon that had been leaned on the head, with subsequent destruction of brain, and in other 2 cases, the weapon had been leaned on the chests, which led to destruction of heart parts. The injuries were caused by the action of striking wave of gunpowder explosion, the air blast type. The cases demonstrate that the gas pressure from the exploding propellant of blank cartridge is powerful enough to penetrate the thoracic wall and the skull.

BackgroundAs a continuation of the previous findings in human fetuses, accidental finding of an accessory vascular component in the posterior part of CAC of human adult cadavers inspired the authors to present and compare its posterior part configuration.Case presentationExamination was carried out on brains of 48 human adult cadavers, routinely dissected at the Institute of Forensic Medicine. The aberrant vessel in the posterior part of four CACs was discovered.Vascular components of the posterior segment of CAC or of the whole CAC were described and photographed. A comparison between fetal and adult cases was also presented.ConclusionsBased on the fact that the age of the four presented cases ranged from 73 to 84 and based on the causes of their death, we concluded that the angioarchitecture of the posterior part of the CAC is a consequence of the embryonic or primitive arterial stabilization and interaction with normal adult vessels.
