There is a need to further anatomically describe the nucleus accumbens (NA), as there is a growing neurosurgical interest in this locus but a limited understanding of its structure. In this study, we evaluated quantitative NA parameters and spatial relationships with adjacent structures found in the telencephalon.
A total of 155 NA specimens from coronal sections and 3 NA specimens from transverse sections were stained using the Mulligan technique as modified by Barnard et al. The distance from the NA to other structures was then measured.
The mean radius of the 155 NAs in the coronal sections was 6.23 ± 0.964 mm, averaging 8.99 ± 2.02 mm from midline (coordinate x), 27.09 ± 3.15 mm from the insula, 12.95 ± 3.21 mm from the outer border of the putamen, 10.52 ± 2.66 mm from the upper border of the caudate, and 8.84 ± 2.93 mm from the midline of the lateral ventricle. The mean distance from the NA center of gravity to the middle of the intercommissural line parallel to the midline (coordinate y) was 17.08 ±3.61 mm, and the mean vertical distance from the intercommissural line to the NA was 8.12 ± 1.265 mm.
We obtained the stereotactic coordinates of (x, y, z) = (8, 17, -8) for the NA. From this and other delineations of the described position of the NA, it is possible to contribute to stereotactic surgical atlases, improving neurosurgical interventions in this structure.
由于神经外科对伏隔核(NA)的兴趣日益浓厚,但对其结构的了解有限,因此需要进一步从解剖学角度描述伏隔核。在本研究中,我们评估了伏隔核的定量参数及其与端脑中相邻结构的空间关系。
对155个冠状切片的伏隔核标本和3个横切片的伏隔核标本采用经巴纳德等人改良的穆利根技术进行染色。然后测量伏隔核与其他结构之间的距离。
冠状切片中155个伏隔核的平均半径为6.23±0.964毫米,距中线(坐标x)平均为8.99±2.02毫米,距岛叶27.09±3.15毫米,距壳核外边界12.95±3.21毫米,距尾状核上边界10.52±2.66毫米,距侧脑室中线8.84±2.93毫米。伏隔核重心到平行于中线的连合间线中点(坐标y)的平均距离为17.08±3.61毫米,连合间线到伏隔核的平均垂直距离为8.12±1.265毫米。
我们获得了伏隔核的立体定向坐标(x,y,z)=(8,17,-8)。基于此以及对伏隔核所述位置的其他描绘,有可能为立体定向手术图谱做出贡献,改善对该结构的神经外科干预。
