It has been already 10 years since the Department of Neurosurgery was founded in Kansai Medical University, and it is quite appropriate at present to sum up the cases which were admitted and treated in our clinic during past 10 years and to analyze them.
Neurosurgical staff, started with five neurosurgeons in 1965, has remarkably expanded and the members who have been intimately connected to our department in the clinical and research activities consist of 12 approved neurosurgeons and nine neurosurgical trainees.
The main categories of neurosurgical cases include cerebral vascular diseases (cerebral aneurysms comprise a little less than 50% of all CVD), craniocerebral injuries and neoplasms of the nervous system in order of frequency. The frequency of the vascular diseases increased progressively year by year and the craniocerebral injuries became less and less frequent. Anual numbers of neoplasm of the nervous system have been fairly constant throughout and among these the glial tumors have been the most frequent. Meningiomas, pituitary adenomas and metastatic tumors are next frequent in the order mentioned.
