Hydrocephalus During The Treatment Endoscope Ventricle Anatomy Structure

In recent years, with the development of neuroendoscope,it was increasingly used in neurosurgical operations. But for the absence of the instrument , the neuroendoscope was usually used in diagnoses and treatments in ventricular disorders. In order to promoting the using of neuroendoscope in surgical treatments for ventricular diseases, the endoscopic anatomical study of lateral ventricle and third ventricle was performed. Objective: (1) To obtain reliable applied anatomic data under the neuroendoscope in ventriculostomy for obstructive hydrocephalus patients. (2) To observe special anatomic structure change in the ventricle of obstructive hydrocephalus patients under the neuroendoscope in ventriculostomy. (3)To offer applied anatomic data for developing neuroendoscope operation through forehead approach. Methods: Eighteen patients with hydrocephalus were operated using neuroendoscope .the anatomic structure and important marks of the lateral ventricle and the third ventricle were observed under the neuroendoscope. Result: (1) Choroid plexus, foramen of Monro, vena thalamostriata, septal vein, mamillary body and aqueduct are important anatomic marks in the ventricle under neuroendoscope. (2) expanding ventricule and foramen of Monro were observed in the obstructive hyduocephalus under the neuruoendoscope,some ventricle anatomic change were obversed under the neuorendoscope. (3) It could get the clearest exposure by using front horn approach under the neuroendoscope. Conclusion: (1) The important anatomic road mark in the ventricle was the 'Y'sharp structive at the foramen of Monro under the neuroendoscope. (2) Longstanding hydrocephalus and raised intracranial pressure can lead to unusual anatomical variants in the ventricle, which may be important when performing endoscopic third ventriculostomy. It require special attention during third ventriculostomy. (3) It could get the clearest exposure by using front horn approach,which was frequent operative approach in the ventricle under the neuroendoscope.
