Investigation on rabbits' cervical vascular explosive injury
Abstract：Aim To investigate the mechanism of cervical vascular blast injury during head- neck region explosive injury.Methods After the detonation of the blast sources from different distances near cervical region,the damages to the rabbits' neck and vessels were examined,and the pressure of the blast waves to both the skins and carotid were measured with PVDF sensors and oscilloscopes.Results Walls of the vessels were damaged and thrombi form on the damaged walls after injury.Crevices or cavities were found in tunica media of arteries.We found micro- thrombi mainly made up of platelets on the walls of arteries and thrombi in veins,which can occlude the cavities of the vessels.Conclusions Strong blast waves can damage cervical vessels and thrombus can easily form on the walls of veins and even occlude the vessels;the walls of arteries can be seriously damaged,and this may account for the possible reasons of pseudo- aneurysm formation.These may provide theoretical basis to save suffers from explosive injury.
