MRI-guided Stereotaxic Targeting in Pigs Based on a Stereotaxic Localizer Box Fitted with an Isocentric Frame and Use of SurgiPlan Computer-planning Software
Journal of Neuroscience Methods. Oct, 2009 | Pubmed ID: 19559051
We present a stereotaxic procedure enabling MRI-guided isocentric stereotaxy in pigs. The procedure is based on the Leksell stereotaxic arch principle, and a stereotaxic localizer box with an incorporated fiducial marking system (sideplates) defining a stereotaxic space similar to the clinical Leksell system. The obtained MRIs can be imported for 3D-reconstruction and coordinate calculation in the clinical stereotaxic software planning system (Leksell SurgiPlan, Elekta AB, Sweden). After MRI the sideplates are replaced by a modified Leksell arch accommodating clinical standard manipulators for isocentric placement of DBS-electrodes, neural tracers and therapeutics in the calculated target coordinates. The mechanical accuracy of the device was within 0.3-0.5 mm. Stereotaxic MRIs were imported to the stereotaxic software planning system with a mean error of 0.4-0.5 mm and a max error of 0.8-0.9 mm. Application accuracy measured on a phantom and on inserted skull markers in nine pigs was within 1 mm in all planes. The intracerebral application accuracy found after placement of 10 manganese trajectories within the full extent of the intracerebral stereotaxic space in two minipigs was equally randomly distributed and within 0.7+/-0.4; 0.5+/-0.4; and 0.7+/-0.3mm in the X, Y, and Z plane. Injection of neural tracers in the subgenual gyrus of three minipigs and placement of encapsulated gene-modified cells in four minipigs confirmed the accuracy and functionality of the described procedure. We conclude that the devised technique and instrumentation enable high-precision stereotaxic procedures in pigs that may benefit future large animal neuroscience research and outline the technical considerations for a similar stereotaxic methodology in other animals.

The microscopic organization of the Göttingen minipig (sus scrofa) hypothalamus was studied using Nissl stain, acetylcholinesterase histochemistry, and immunohistochemical staining for calretinin, tyrosin hydroxylase, oxytocin, vasopressin, and orexin A. Mediolaterally the minipig hypothalamus can be divided into three cytoarchitectonic distinct longitudinal zones. The periventricular longitudinal zone comprises the supraoptic, paraventricular, median preoptic, anteroventral periventricular, suprachiasmatic and arcuate nuclei. The medial longitudinal zone includes the prominent medial preoptic, ventromedial, dorsomedial and medial mammillary nuclei. Together with the anterior hypothalamic area, they can be further divided into distinct subregions. The dorsal and posterior hypothalamic areas and the retromammillary and lateral mammillary nuclei are cyto- and chemoarchitectonically distinct but cannot be further divided into subregions. The cell sparse, fiber rich lateral longitudinal zone comprises the lateral preoptic and lateral hypothalamic area as well as the perifornical, lateral tuberal and tuberomammillary nuclei. The findings presented here indicate that the cyto- and chemoarchitecture of the Göttingen minipig hypothalamus is comparable to that of rat, landrace pig, monkey, and human and that the Göttingen minipig may be well suited for future, non-primate, large mammal, hypothalamic research.
