Lateral ventricular neuroendoscopic anatomy through the interhemispheric transcorpus callosal approach
Objective To provide anatomical basis for lateral ventricular neuroendoscopic surgery through the interhemispheric transcorpus callosal approach. Methods The anatomic investigation of the lateral and third ventricle was performed in 10 adult cadaveric head specimens, through interhemispheric transcorpus callosal approach. Results The thickness of corpus callosum was (6.1±1.2) mm, the sagittal and transverse diameters of interventricular foreman (5.6±1.4) mm and (3.0±1.6) mm, and the sagittal and transverse diameters of interthalamic adhesion (6.3±1.8) mm and (3.4±1.2) mm. There were very less drainage veins to the sagittal sinus anterior to the coronal suture. The body and front horn of the lateral ventricle, the "Y" shape structure of interventricular foreman could be observed under different angular neuroendoscope. Cut size of 2 cm on corpus callosum than that of 1.5 cm was better to reveal the structures and exert operation under a rigid endoscopic surgery. Conclusions Interhemispheric transcorpus callosal approach is a safe and valuable way to treat affection in double lateral ventricle, area of interventricular foreman and the third ventricle.
