31Minimally invasive (ALARA) and function preservation neurosurgical treatment using the state-of-the-art medical careSummary of ActivityAt the Department of Neurosurgery, Shinshu University School of Medicine, we conduct surgical treatment for cerebrovascular disorder, brain tumors, spinal cord diseases, etc. with a consistent treatment policy using “as less as reasonable achievable (ALARA) surgery and function preservation therapy” by making full use of state-of-the-art medical care. The goal is to cultivate more excellent neurosurgeons by performing high level brain surgical interventions in collaboration with all affiliated hospitals. For each neurosurgical disease, we are conducting research on the following themes:・ Minimally invasive surgical approach: Development of surgical methods and safer surgical approach for the skull base lesion・ Surgical instrument: Development of surgical instruments to make surgery safer and more reliable ・ Surgical simulation: Development of surgical simulation with three dimensional neuro-images・ Microneurosurgical anatomical study: Understanding and study of focal brain anatomy for more precise neurosurgical operation・ Intraoperative neural function monitoring and mapping: Research on evaluation of neural functions using electrophysiological techniques during surgery for function preservation・ Development of surgical robotics: Development of robot-assisted surgery system for minimally invasive neurosurgery・ Genetic analysis of malignant brain tumor: Genetic analysis, optimal chemotherapy of the malignant brain tumorDivisions: 1. Cerebrovascular neurosurgery 2. Brain tumor (intra- and extraaxial) 3. Functional neurosurgery 4. Minimally invasive spine and spinal cord neurosurgery 5. Neuroendoscopic surgery 6. Endovascular treatmentNeurosurgeryVascular surgery is the basic and important subspecialty（Chief: Associate Prof. Tetsuyoshi Horiuchi）NeurosurgerySummary of ActivityCerebrovascular disorder is a disease that was previously known as stroke. Stroke suddenly induces speech disturbance, hemiparesis, cognitive dysfunction, etc. It divides into two groups (ischemic and hemorrhagic types). In our laboratory, we are energetically researching & developing surgical treat-ment methods to reduce the morbidity & mortality that attribute to cerebrovascu-lar disorders. We are focused on aneurysm clipping and open embolectomy.・ Clipping surgery for internal carotid artery aneurysm ・ Revascularization for acute ischemic stroke ・ Development of new surgical approaches There are two kinds of treatments for stroke. One is the direct surgery. The other one is the endovascular surgery. Both treatments are important. Direct surgery will be further developed due to advanced neuroimaging and instruments. This laboratory rears vascular neurosurgeons.Many patients have been involved in stroke. Therefore, basic knowledges of stroke are very useful for medical doctors especially for neurologist, emergency physician, and psychiatrist.Research subjectOutlook for researchOutlook for students after graduationone of our interesting topics .The left paraclinoid aneurysm after clip-ping The left paraclinoid aneurysm before clip-ping
