Preface

Hydrocephalus is a common neurosurgical disease that is frequently secondary to other neurosurgical diseases, which contributes to its poor prognosis. Advancements in hydrocephalus research in recent years have provided a more comprehensive understanding of its pathogenesis. Previously, it was believed that hydrocephalus was caused by a flow disorder of cerebrospinal fluid circulation. Now, however, scholars have realized the limitations of this theory and pioneered the theory of brain tissue penetration, which has enriched the etiological research of hydrocephalus. In addition, advancements in neurosurgery technology have led to improved treatment methods such as ventriculoperitoneal shunt, endoscopic third ventriculostomy, neuroendoscopic ventriculostomy, choroid plexus coagulation, neuroendoscopic aqueductoplasty, and others. This book discusses the latest advances in hydrocephalus treatment, including recent research developments in ventriculoperitoneal shunt surgery and neuroendoscopic treatment. Furthermore, it examines rare types of hydrocephalus, including hydrocephalus associated with myelomeningocele, hydrocephalus in tuberculous meningitis, hydrocephalus in arachnoid hemorrhage, and pediatric hydrocephalus.

We would like to thank all the authors for their contributions. We would also like to acknowledge the encouragement, motivation, and assistance from the Beijing Municipal Administration of Hospitals Incubating Program (PX2020039), Beijing, China, and Tsinghua Precision Medicine Foundation (20219990008), Tsinghua University, Beijing, China. We are grateful to the Author Service Manager Ms. Tea Jurcic at IntechOpen for her dedication and hard work in ensuring the smooth publication of this book. Finally, we owe a debt of gratitude to Professor Zhongcheng Wang, academician of the Chinese Academy of Engineering and the founder and pioneer of Chinese neurosurgery, for without his tireless efforts over the decades, Chinese neurosurgery would not be what it is today.
