title: Histological examination of the carotid bifurcation in case of violence against the neck.
abstract: The carotid body and carotid sinus are localized in the area of the carotid bifurcation and respond to pressure fluctuations in the arterial blood vessel system. In case of irritation or stimulation, nervous impulses can reflexively increase the ventilation or slow down the heart rate and blood pressure, respectively. The external stimulation of the carotid sinus by neck compression with subsequent bradycardia or asystolia, especially in pre-existing heart-disease, is discussed controversially in the literature. Histological examination of the tissue of the carotid bifurcation, particularly with regard to haemorrhage as an indication of tissue trauma, should be carried out in terms of simple and easy feasibility in routine diagnostics. In 20 cases of violence against the neck and additionally 82 cases of a control group without neck trauma and variable causes of death, the carotid bifurcations were examined histologically. Only in one case of violence against the neck haemorrhage was found, which suggested a direct trauma to the tissue of the carotid bifurcation, but evidence of lethal cardiac reflex was not found in any case.
