The Department of Neurosurgery at Peking University International Hospital was established in October 2015, jointly built with Beijing Tiantan Hospital under the approval of the Beijing Municipal Health Commission. It has grown into a large regional neurosurgery center integrating clinical care, education, and research, with two wards and 84 beds. In 2021, it was designated as a National Health Commission Neurointervention Construction Center and received a discipline influence nomination in the Fudan University Rankings. In 2023, it was selected as one of the first batch of member units of the "National Clinical Medical Research Sub-center for Neurological Diseases – Brain-Heart Comorbidity Collaborative Group." In 2024, it signed an agreement to become a member unit of the Peking Union Medical College Hospital Neurosurgery Medical Alliance. Also in 2024, it was approved as a Standardized Specialist Training Base by Peking University Health Science Center. The department has 24 physicians with an average age of 39, over 80% of whom hold doctoral degrees. Among them, there are 4 chief physicians, 8 associate chief physicians, 9 attending physicians, and 3 resident physicians, along with 2 intraoperative MRI technologists. In terms of nursing, the department meets international standards and applies the concept of early rehabilitation. It is the first nursing unit in our hospital to be designated as a "Nursing Service Demonstration Base." The department primarily treats patients with cerebrovascular diseases (cerebral hemorrhage, cerebral infarction, aneurysms, vascular stenosis), cranial and intracranial tumors, spinal and spinal cord diseases, craniocerebral trauma, congenital nervous system malformations, hydrocephalus, and functional neurosurgical conditions (epilepsy, disorders of consciousness, Parkinson's disease, pain). The department is equipped with advanced technology, including a hybrid operating room, a high-field intraoperative MRI composite operating room, neuronavigation, stereotactic puncture systems, neuroendoscopy, intraoperative neurophysiological monitoring, intraoperative ultrasound, and neurosurgical robots. The department has led multiple national and provincial-level research projects and undertaken numerous device and drug clinical trials. It served as the lead author for the world's first "Chinese Guidelines for the Treatment of Intracranial Aneurysms with Flow Diverters," the "Chinese Guidelines for the Clinical Management of Ruptured Intracranial Aneurysms (2024 Edition)," and the "Chinese Guidelines for the Clinical Management of Unruptured Intracranial Aneurysms (2024 Edition)," among other clinical guidelines and consensus documents. It has published over 60 related clinical research articles, including more than 50 SCI papers, and obtained over 10 national utility model and invention patents.
