Abstract：Objective To summarize the third ventricular anatomical features which could make infant less than 1 year old with noncommunicating hydrocephalus get successful endoscopic third ventriculostomy (ETV). Methods Clinical data of 16 infants less than 1 year old with noncommunicating hydrocephalus were reviewed retrospectively. Based on preoperative MRI information and ventriculoscopic films, the relationships between anatomical features of the third ventricle and surgical outcomes were analyzed. Results According to the MRI examination, the abnormal anatomical features of the third ventricle that might interfere with ETV included huge massa intermedia, sloping of the third ventricular floor, narrow anteroposterior diameter of the third ventricle, narrow prepontine cistern and third ventricle floor thickness more than 2 mm. While the abnormal endoscopic findings included narrow foramen of Monro, hypertrophy of the anterior commissure, huge massa intermedia and opaque third ventricular floor. The risk of ETV failure would increase if there were both narrow prepontine cistern and third ventricle thickness more than 2 mm, or both huge massa intermedia and narrow anteroposterior diameter of the third ventricle. Conclusion The anatomical features of the third ventricle gotten in preoperative MRI evaluation and intraoperative endoscopic findings are very important for successful performance of ETV.
