S urgical approaches to the lateral ventricle always require passage through one and often multiple fiber tracts to reach their target. These approaches remain a challenge because of the deep location and variable shape and size of the ventricles, their covering mantle of tracts, and relationships to important neural structures such as the thalamus and internal capsule. 55,75,84 In addition, a number of tracts course in the walls of the ventricle where they are separated from the cerebrospinal fluid by only a thin layer of ependyma and would likely be exposed to the greatest possibility of damage by hydrocephalus.84,124 Recent studies have focused on the relationships of the fiber tracts to eloquent cortical areas and avoiding the optic radiations in approaches to the lateral ventricle. 16,41,48,59,63,75,89,92,94,125 The aim of the present study was to explore the relationships of the tracts to the lateral ventricles and the various surgical approaches to the ventricles and to examine the anatomy and syndromes related to ventricular enlargement. MethodsForty adult human formalin-fixed cadaveric hemispheres (20 brains) were examined under magnification that ranged from ×6 to ×40. The dura, pia, arachnoid, and surface vessels were gently removed. All specimens were frozen in water for at least 2 weeks at -16°C, as described by Klingler, to separate the tracts and facilitate dissection. 51 After freezing, the specimens were thawed and rinsed of formalin under tap water for at least 1 hour. Prior OBJECTIVEThe relationship of the white matter tracts to the lateral ventricles is important when planning surgical approaches to the ventricles and in understanding the symptoms of hydrocephalus. The authors' aim was to explore the relationship of the white matter tracts of the cerebrum to the lateral ventricles using fiber dissection technique and MR tractography and to discuss these findings in relation to approaches to ventricular lesions. METHODS Forty adult human formalin-fixed cadaveric hemispheres (20 brains) and 3 whole heads were examined using fiber dissection technique. The dissections were performed from lateral to medial, medial to lateral, superior to inferior, and inferior to superior. MR tractography showing the lateral ventricles aided in the understanding of the 3D relationships of the white matter tracts with the lateral ventricles. RESULTS The relationship between the lateral ventricles and the superior longitudinal I, II, and III, arcuate, vertical occipital, middle longitudinal, inferior longitudinal, inferior frontooccipital, uncinate, sledge runner, and lingular amygdaloidal fasciculi; and the anterior commissure fibers, optic radiations, internal capsule, corona radiata, thalamic radiations, cingulum, corpus callosum, fornix, caudate nucleus, thalamus, stria terminalis, and stria medullaris thalami were defined anatomically and radiologically. These fibers and structures have a consistent relationship to the lateral ventricles. CONCLUSIONS Knowledge of the relationship of the white matter tracts o...

The subparietal and parietooccipital sulci: An anatomical study

et al. 2013

View full text Add to dashboard Cite

The subparietal and parietooccipital sulci are both located on the medial surface of the brain. Both of these sulci reveal significant variability in pattern and complexity. Both subparietal and parietooccipital sulci play an important role as surgical landmarks using posterior interhemispheric parietooccipital approach to lesions located adjacent to the ventricular trigon deep to the cingulate gyrus. The aim of this study is to analyze variations in the patterns of the subparietal and parietooccipital sulci and to emphasize their surgical importance. Fifty-six formalin-fixed cadaveric cerebral hemispheres from 28 adult humans are examined. Subparietal and parietal sulci patterns, variations and their relationship with the cingulate sulcus are studied according to the terminology introduced by Ono et al. The H-pattern was observed in 50% (n = 28) of all hemispheres, being the most common pattern of the subparietal sulcus. The Straight pattern was observed in the 30.4% (n = 17) of all hemispheres, being the most common pattern of the parietooccipital sulcus. Furthermore, more detailed results among the patterns, connections, side branches and the relationship with the adjacent sulci are given. Our study further confirms the complexities in the patterns of the subparietal and parietooccipital sulci and demonstrates that these sulci fall within an expected range of variations. Better knowledge of these variations will further help neurosurgeons to navigate easily during approaches involving the medial surface of the parietal lobe. Clin.
