Third Ventriculostomy has been proposed as the procedure of choice for many patients with acquired obstructive hydrocephalus. Various techniques have been used to perform this procedure. This report describes the use of magnetic resonance images to guide the performance of a stereotactic third ventriculostomy with a rigid endoscope, allowing continuous direct visualization. This procedure has been performed on three patients, yielding clinical improvement without the need for extracranial shunting. Magnetic resonance imaging allows accurate identification of the important anatomical landmarks (i.e., foramen of Monro and interpeduncular cistern), with axial, coronal, and sagittal images, and is readily used in conjunction with the Cosman-Roberts-Wells stereotactic apparatus.
第三脑室造瘘术已被提议作为许多获得性梗阻性脑积水患者的首选手术方法。人们使用了各种技术来实施该手术。本报告描述了利用磁共振成像来指导使用刚性内窥镜进行立体定向第三脑室造瘘术，从而实现连续直接可视化。该手术已在三名患者身上实施，取得了临床改善效果，且无需进行颅外分流。磁共振成像能够通过轴向、冠状和矢状图像准确识别重要的解剖标志（即室间孔和脚间池），并易于与科斯曼 - 罗伯茨 - 韦尔斯立体定向设备联合使用。
