目的:为主动脉肾神经节、肾丛的影像学研究提供形态学基础,为提高对主动脉肾神经节的影像诊断提供参考。方法:对75具成人尸体标本主动脉肾神经节的位置、形状、长度、宽度和厚度进行解剖观测,对6具成人尸体标本的主动脉肾神经节在断面、CT、MRI扫描图像上进行观察。结果:主动脉肾神经节位于肾静脉的后方,肾动脉表面和附近,其形态可分为椭圆形、长条形、星形、圆形和三角形;主动脉肾神经节横断面观察,组织致密,无管腔横断面;在CT、MRI扫描图像上能分辨其结构。结论:在断面标本中主动脉肾神经节与淋巴结的区别可通过观察其横断面组织是否致密,有无管腔横断面来确定;在尸体标本上主动脉肾神经节与淋巴结的区别可通过手触膜组织的硬度,相连的纤维状结构是否坚韧,是否有内脏小神经相连来确定。
OBJECTIVE: To provide a morphological basis for the imaging studies of aortic renal ganglion and renal plexus, and to provide reference for improving the diagnosis of aortic renal ganglion. Methods: The anatomical observation of the location, shape, length, width and thickness of the aortic renal ganglion in 75 adult cadaver specimens was performed. The aortic renal ganglions of 6 adult cadaver specimens were observed on the sectional, CT and MRI images . Results: The aortic renal ganglion was located behind the renal vein and near the renal artery. The morphology of the aortic renal ganglion can be divided into oval, elongated, star, circle and triangle. The aortic renal ganglion was observed in transverse section and tissue dense , No lumen cross section; CT, MRI images can be resolved on its structure. Conclusion: The difference between aortic renal ganglion and lymph node in the cross-sectional specimens can be confirmed by observing whether the cross-sectional tissue is dense or not with the cross-section of the lumen. The difference between the aortic renal ganglion and the lymph node on the body specimen can be confirmed by hand Tissue hardness, connected to the fibrous structure is tough, if there are visceral nerves connected to determine.
