| Research Abstract |
Topographic anatomy of the cerebral arteries and surrounding meninges was investigated by the methods of simulation surgery for donated cadavers. The internal carotid artery penetrating the cavernous roof and the vertebral artery penetrating the dura mater around the foramen magnum were dissected under the operating stereomicroscope. Removed specimen of the vertebral artery was histologically studied. The adventitia of the specimens from the epidural and intradural (i.e. subarachnoid) spaces included fine peripheral nerves and small venules. Thus the outer structure of vertebral artery has similar characteristics before and after the penetration of the dura mater. Further investigation should be directed to the relation between the structures of arterial surface and pathological vulnerability causing dissecting aneurysms.
CCD camera was equipped with the operative stereomicroscope by this grant-in-aid. Digital video monitoring system enabled us recording and demonstration of fine structures under the microscope. The environment of simulation surgery has been improved by introducing high speed drill and other instruments of operation room. Research of clinical anatomy needs collaboration between anatomists and clinicians. Simulation surgery offers the opportunity for rehearsal of challenging operation and confirmation of topographic anatomy. Furthermore it is a good chance for medical students and young residents to learn practical anatomy and therapeutic strategy.
