| Popis: | We examined histologically the meninges adherent to traumatic lesions of a patient with brain death sustained for 101 days and observed both early and late reactions of wound healing at the same site of the dura mater. Some parts of the dura mater were thick and histological examinations revealed formation of new vessels and fibrosis with strong positive reaction for iron and fat staining. We also observed fresh haemorrhage and some cell infiltration in the dura and fresh haemorrhage in a small piece of necrotic brain tissue adhered to the dura mater, while other areas of the brain tissue were completely necrotic, enabling the sites of head injury to be localised. These observations suggested that the blood flow in the dura mater fluctuates due to a change of microenvironment, which probably causes repeated secondary petechial haemorrhages in the dura and its adherent necrotic brain tissue, even 101 days after brain death. |
