Abstract:
Objective To investigate an accurate and applicable localizing method of puncture point for neuroendoscopic third ventriculostomy in neurosurgery so as to ensure that the neuroendoscope is led to the anterior membrane of mammillary body on the base of third ventricle directly. Methods Based on the MR characteristics including multiple directions and angles and high soft tissue resolution, the coordinate of puncture point was measured and calculated for neuroendoscopic third ventriculostomy in MRI. Results~The position of puncture point for neuroendoscopic third ventriculostomy was (127.2?9.9)mm to nasal root, or (17.1?5.6)mm in front of coronal suture and (20.3?4.7)mm to sagittal suture. The angle between the puncturing line and the cerebral falx was (12.3?1.9)?, and the depth from scalp to anterior membrane of mammillary body was (89.3?10.4)mm. Conclusion MRI-guided localization for neuroendoscopic third ventriculostomy is an accurate, simple, safe, painless, and applicable method.
