A simple and safe technique for performing an endoscopic third ventriculocisternostomy is described using a small-diameter semirigid neuroendoscope in conjunction with a perforated ventricular catheter to bluntly fenestrate the floor of the third ventricle. All previous descriptions involve the initial use of an introducer sheath that in our experience lends to loss of cerebrospinal fluid, consequently distorting the anatomic landmarks of the third ventricle as well as compromising the crucial concave shape of its floor. Our technique limits the loss of cerebrospinal fluid volume, therefore, reducing the chance of basilar artery complex perforation as a consequence of distortion of third ventricular landmarks and loss of third ventricular floor concavity.
本文描述了一种简单且安全的内镜下第三脑室造瘘术，该技术使用小直径半刚性神经内镜结合带孔脑室导管，钝性造瘘第三脑室底部。以往所有描述均涉及首先使用导入鞘，而根据我们的经验，这会导致脑脊液流失，进而扭曲第三脑室的解剖标志，并破坏其底部至关重要的凹形结构。我们的技术限制了脑脊液量的流失，因此减少了因第三脑室标志扭曲和第三脑室底部凹形结构丧失而导致基底动脉复合体穿孔的可能性。
