用墨汁灌注连续切片法,研究成人桡神经干的微血管构筑。桡神经的不同部位血管层次及动、静脉内径均有不同程度的变化,但都存在外膜和束内血管层。各层血管内径在神经的不同部位有一定的变化,同外来营养神经的血管外径有密切关系。束内血管层中,臂部血管面积比值比前臂部小,差异显著。在桡神经纵切片中,外膜血管网眼密度较高,束内血管网眼密度最低。 Continuous perfusion with ink perfusion method to study the microvascular architecture of adult radial nerve stem. Radial nerve in different parts of the vascular levels and arterial and venous diameter have varying degrees of change, but there are outer membrane and bundle vascular layer. Each layer of vascular diameter in different parts of the nerves have some changes, with the external nutrient nerve vascular diameter are closely related. Beam vascular layer, the ratio of arm vascular area than the forearm, significant difference. Radial nerve longitudinal slices, the outer membrane vascular network density is higher, the lowest density of vascular bundles within the tract.
