Introduction:
We report herein the technical considerations for endoscopic septostomy in a case of hydrocephalus associated with tuberous sclerosis.
Case Report:
A 17-year-old boy presented with visual and gait disturbances. Computed tomography revealed an intraventricular mass obstructing the foramen of Monro bilaterally and marked hydrocephalus. First, we planned a ventriculo-peritoneal shunt with endoscopic septostomy using a biportal approach to resolve the hydrocephalus. Guidance by a rigid endoscope inserted into the anterior horn of the left lateral ventricle allowed us to easily and safely perform septostomy using the fiberscope inserted into the anterior horn of the right lateral ventricle.
Conclusion:
A biportal approach such as the dual endoscopic technique is useful in the treatment of complicated intraventricular lesions with loss of midline structures.
