Sudden death after fatal percussion of the cervical neurovascular bundle

Atypical compression of the neck may be classified as asphyxia in which the external compression on the cervical anatomical structures occurs in a peculiar manner. In such cases, death occurs due to the combination of several pathophysiological phenomena, such as respiratory, vascular, and nervous. When the mechanical action on the neck is violent and rapid, it is more correct to use the word percussion rather than compression. Usually there are no skin lesions of special significance in this type of neck percussion, unlike the cases of choking, strangulation, and hanging, and the diagnosis is challenging. It is important to carefully evaluate the body during the autopsy to identify which pathophysiological mechanism caused the death.

A young woman died immediately after being struck by a concrete beam at the level of her neck. The woman was on vacation with her boyfriend and decided to hang from a concrete beam suspended between two columns to take a souvenir photo when the beam suddenly broke and fell on her. The autopsy revealed multiple abrasions, swelling, and lacerations to the face, neck, and chest. Internal examination revealed primarily the presence of hemorrhagic infiltration in the anterior cervical compartments and lacerations of various organs, including the trachea.

Based on all the obtained data, including toxicological and histological, the cause of death was atypical ab extrinsic percussion of the neck, directed particularly at the right cervical neurovascular bundle.
