Objective of the study was the development of criteria of the vagus nerve system injuries in patients with nonfatal head and spinal cord injuries, and fining evidence of its relationship to a sudden cardiac death. Materials and мethods: system of the vagus nerve, AV nod and changes in cardiomyocytes in 45 cases of death (20 – head and spinal cord injuries, and 25 - acute coronary insufficiency) were investigated.
Results: Damages of, and hemorrhages in the jugular ganglion and nervous trunks as a result of head and spinal cord injuries were found. Atrophic changes in the jugular ganglion were found in cases of deaths from coronary insufficiency. In all cases hemosiderosis of the pia of the medulla oblongata was found.
Conclusions: Identified injuries of central and peripheral parts of the vagus nerve system in patients with head and spinal cord injuries may allow defining the pathogenesis of post- traumatic coronary spasm and ventricular fibrillation.
