Comparison Between Transcortical and Interhemispheric Approaches to the Atrium of Lateral Ventricle Using Combined White Matter Fiber Dissections and Magnetic Resonance Tractography
摘要
Most commonly reported lesions in the region of the atrium include meningiomas, cavernomas, gliomas, metastases, and arteriovenous malformations. The surgical corridor to treat such lesions has been attributed with the risk on developing Gerstmann syndrome, visual deficits, speech deficits, and memory and behavioral abnormalities due to injury of the superior longitudinal fasciculus (SLF), optic radiations, arcuate fasciculus (AF), cingulum, and dorsal part of the corpus callosum [2, 3, 4–7]. Selection of the surgical approach to atrium depends on nature, size, location, vascularity of the lesion, and surgeon experience. The optimal surgical approach should minimize brain retraction and brain resection; however, the neurosurgeon may select an approach that needs long distance to reach the atrium in order to minimize the resection of brain tissue and avoid postoperative morbidity [7, 8].
