| Outline of Final Research Achievements |
Histopathological features of cerebral arteries focusing on the medial smooth muscle cells for forensic diagnosis of sudden death due to cerebral arterial rupture were examined. In cases of vertebral artery dissection, segmental arterial mediolysis was observed as a causative lesion in all examined cases. The response of mesenchymal cells found at the rupture site was considered to be a useful finding for distinguishing from traumatic vertebral arterial rupture. In the cases of a saccular aneurysm, the morphology and distribution of the medial smooth muscle cells enables to evaluate growth course of the aneurysm. That is useful for forensic practice in the point of grasping the case's prenatal course.
