MICROSURGICAL ANATOMY OF THE CONNECTIONS OF CAUDATE NUCLEUS AND PSYCHOSURGICAL CONSIDERATIONS : A UNIQUE CADAVER STUDY
Öz
Aim: Caudate Nucleus has been discussed as a target for new treatments of neurologic and psychiatric diseases but the connectivity remains unclear for both microsurgical procedures and stereotactic interventions despite the basic neuroanatomical knowledge. We aim to reveal the anatomic relationship of the caudate nucleus using fiber dissection technique.
Material and Methods: Four brain specimens (8 Hemispheres) were frozen for 15 days at -16 °C according to Klingler’s Technique. The freezing process facilitates the dissection of the fiber tracts. After completion of the freezing process, the dissections were stepwise performed from lateral to medial, under x6 to x40 magnification using a surgical microscope, two and three-dimensional anatomic pictures were obtained.
Results: Stepwise microsurgical fiber dissection of the Caudate Nucleus and adjacent areas were dissected. The cortical areas communicating with and overlying the Caudate Nucleus are reviewed. Frontocaudate Connection Fibers and Temporocaudate Fibers were intense and the microsurgical anatomy of the area were revealed.
Conclusion: Psychosurgery has been used primarily in the treatment of depression when the medical treatments were not adequate. Deep Brain Stimulation of Nucleus Caudatus is not standard treatment procedure in the clinical practice. It may be considered that different parts of the Caudate Nucleus and connection fibers associated with Caudate Nucleus can be used as a target for Deep Brain Stimulation which could be an alternative treatment for Parkinson's Disease, Obsessive Compulsive Disorder and Major Depression.
