- Аннотация: Background: This study provides an anatomical description of a novel supracerebellar infratentorial invertedsubchoroidal (SIIS) approach to the lateral ventricle. An illustrative case is presented in which this approach wasused to simultaneously resect two tumors residing in the posterior fossa and lateral ventricle.Methods: The SIIS approach was performed on five cadaveric heads using microsurgical and endoscopictechniques. Target points were defined in the lateral ventricle, and quantitative analysis was performed to assesslimits of exposure within the lateral ventricle. Two coronal reference planes corresponding to the anterior andposterior margins of the lateral ventricle body were defined. Distances from target points to reference planes weremeasured, and an imaging-based predicting system was provided according to obtained measurements to guidepreoperative approach selection.Results: Mean (standard deviation) distances between the predefined target points indicating the anterior limitsand the anterior plane were 9 (7.0) mm, 11 (5.8) mm, and 7 (5.1) mm; posterior limits had distances of 8 (3.0)mm, 17 (9.2) mm, 15 (9.2) mm, and 9 (7.2) mm to the posterior plane. Limiting factors of the choroidal fissuredissection were the venous angle anteriorly and thalamocaudate vein posteriorly. The position of the venous anglehad a high negative correlation with the anterior exposure limit (r = –0.87, P < 0.001; r = –0.92, P < 0.001).Conclusion: A step-by-step anatomical description of a new SIIS approach is given, and a quantitative descriptionof the limits of the exposure is provided to evaluate the application of this approach. 13 стр.
