The aim of this study was to provide detailed information about the arterial vascularization of the splenium of the corpus callosum (CC). The splenium is unique in that it is part of the largest commissural tract in the brain and a region in which pathologies are seen frequently. An exact description of the arterial vascularization of this part of the CC remains under debate. Thirty adult human brains (60 hemispheres) were obtained from routine autopsies. Cerebral arteries were separately cannulated and injected with colored latex. Then, the brains were fixed in formaldehyde, and dissections were performed using a surgical microscope. The diameter of the arterial branches supplying the splenium of the CC at their origin was investigated, and the vascularization patterns of these branches were observed. Vascular supply to the splenium was provided by the anterior pericallosal artery (40%) from the anterior circulation and by the posterior pericallosal artery (88%) and posterior accessory pericallosal artery (50%) from the posterior circulation. The vascularization pattern of the splenium differs in each hemisphere and is usually supplied by multiple branches. The arterial vascularization of the splenium of the CC was studied comprehensively considering the ongoing debate and the inadequacy of the studies on this issue currently available in the literature. This anatomical knowledge is essential during the treatment of pathologies in this region and especially for splenial arteriovenous malformations.
本研究旨在提供关于胼胝体压部（CC）动脉血管化的详细信息。胼胝体压部是独特的，因为它是大脑中最大的连合束的一部分，也是经常出现病变的区域。该部分 CC 的动脉血管化的准确描述仍存在争议。从常规尸检中获得了 30 个成人脑（60 个半球）。单独对脑动脉进行插管并用有色乳胶进行注射。然后，将大脑用甲醛固定，并使用手术显微镜进行解剖。研究了供应 CC 压部的动脉分支在其起源处的直径，并观察了这些分支的血管化模式。CC 压部的血管供应来自前胼胝体动脉（40%），来自前循环，以及来自后胼胝体动脉（88%）和后辅助胼胝体动脉（50%），来自后循环。每侧半球的血管化模式不同，通常由多个分支供应。考虑到目前文献中对这一问题的研究不足以及正在进行的争论，我们全面研究了 CC 压部的动脉血管化。这种解剖学知识对于该区域病变的治疗至关重要，特别是对于胼胝体动静脉畸形。
