Sažetak

The aim of this review is to recapitulate anatomic landmarks with special attention to the cases with deformed ventricles caused by chronic hydrocephalus. In the modern era, neuroendoscopy has had an increasingly prominent role in neurosurgery. As attention has focused the development of minimally invasive surgical methods, neuroendoscopy has advanced both as an independent treatment modality for various neurologic disorders and as an adjunct to microneurosurgery. In addition to its advantages, neuroendoscopy is associated with unique obstacles that must be anticipated and accounted to prevent complications. Use of neuronavigation which is of immense help in most of neurosurgical cases is of limited use in neuroendoscopy. Knowledge of anatomical landmarks is obligatory to successfully perform endoscopic third ventriculostomy (ETV), a golden standard in treatment for obstructive hydrocephalus. For ETV, the landmarks are choroid plexus in choroid fissure, septal and talamostriate veins to identify Foramen of Monroe. Once when foramen is traversed, navigation through third ventricle is based on paired mammillary bodies from which the surgeon can discern the midline and anterior retrochiasmatic space. In the space between retrochiasmatic recess and mammillary bodies is the flat and often thinned floor of the third ventricle. Ventriculocisternostomy is performed by blunt perforation and dilatation with Fogarty 3Fr catheter.
