Massive Brainstem and Cerebellum Infarction Due to Traumatic Extracranial Vertebral Artery Dissection in a Motor Traffic Accident: An Autopsy Case Report
Traumatic unilateral vertebral artery (VA) injury can cause focal thrombosis and may block the basilar artery which can further lead to ischemic stroke and massive cerebral infarction and subarachnoid hemorrhage and even rapid death. Here, we present an autopsy case with a traumatic extracranial VA dissection in a motor traffic accident, and the identification of cause of death underwent 2 autopsies. A 62-year-old male pedestrian collided with the right rearview mirror of a car and fell down to the ground. He complained pains in the head and neck. Head computed tomography (CT) showed a right linear temporal bone fracture a...

A Case of Bilateral Extracranial Internal Carotid Artery Dissection Due to the Helmet Strap After Motorcycle Crash
The authors report a case of a man who developed stroke symptoms a few days after a road accident on his motorcycle. Radiographic examinations revealed the presence of bilateral dissection of the extracranial internal carotid arteries with signs of involvement of the brain parenchyma. The location, timing, and presentation lead to the conclusion that the carotid lesions were secondary to the motorcycle collision; in particular, we suppose that it is due to the pressure exerted by the helmet strap worn. Although helmets have undoubtedly prevented serious injuries, this report highlights that the helmets themselves may caus...

Cervical Arterial Injury After Strangulation-Different Types of Arterial Lesions.
We report three unusual cases where strangulation induced immediate stroke. CAI were examined using brain CT scan and Doppler ultrasonography in the three cases and then by autopsy in one of the victims. One of the two victims who survived the attempted strangulation had a unilateral carotid dissection, whereas in the other victim, no arterial dissection or thrombosis was observed. As regards the deceased victim, the autopsy confirmed the bilateral dissection showed on CT scan and Doppler ultrasonic examination and revealed that both carotid arteries were dilated up to two times the normal diameter. Microscopic examination...
