Abstract:
To investigate the mechanism of common carotid artery injury produced by explosion in neck region, and to determine the severity of carotid injury based on the injury of neck and the pressure of blast waves. After the detonation of the blast source at different distances, the injuries to rabbits' neck and carotid artery were examined, and the pressure of the blast waves to both skins and common carotid artery were measured with PVDF(polyvinylidene fluoride)sensors and oscilloscope. The endothelium of the injured carotid artery desquamated and micro thrombus formed on the arterial walls the after injury. Disruptions in the tunica media might account for pseudo aneurysm formation. These results offered experimental evidences pseudo aneurysm and thrombus formation in the carotid artery after an explosion in the neek region.
