[Extra- and intracranial injuries of the cerebral arteries as a sequela of assault].

The case of an 47-year-old man is reported, who was injured in a fight while under the influence of alcohol. The culprit knocked him down and stamped several times on the left side of his head. The victim became unconscious. At the hospital, subarachnoid hemorrhage and massive ventricular bleeding was diagnosed via CT. Despite the implantation of a ventricular shunt, there was repeated massive cerebral pressure and arterial bleeding. Brain death occurred after 8 days. The main finding at autopsy was nearly complete disruption of the left inferior posterior cerebellar artery as the source of the lethal bleeding. The histological examination showed some additional, incomplete ruptures of this vessel and of the left intracranial vertebral artery. This is a typical result of "minor head injuries" sustained in fights: arterial rupture (ipsilateral) as a result of overstretching. Fracture of the left zygomatic arch and maxilla; no skull fracture; no primary traumatic brain damage. The extracranial carotid arteries were intact. When the vertebral arteries were examined (in the undamaged cervical spine), there was a surprising finding: distant dissection of the right vertebral artery between C1 and C2, which perhaps occurred as a result of compression (contralateral to the impact) of this region.
