皮神经具有到达动脉的血管分支（VB），并且被认为参与动脉收缩。目的：研究足背第一、二跖骨基底部凹陷处的太冲穴与足皮神经VB的解剖学和组织学关系。对40侧尸体足进行了腓深神经内侧分支的解剖学研究。远端追踪MBDPN以确定VB到达动脉的点。测量该点与LR3之间的距离。用酪氨酸羟化酶（TH）免疫组化染色对VB内的交感神经纤维进行组织学观察。所有标本（100%）均观察到足背动脉分支。LR3与MBDPN的VB到达动脉的点之间的平均距离为3.2 ± 2.6 mm。在VB中，70%分布在LR3近端。此外，TH阳性纤维存在于VB。结果表明，部分MBDPN分布于足背动脉，并含有交感神经纤维。我们还发现，VBs的分布区域接近LR3。我们的研究提供了解剖学证据，LR3是一个特定的区域，其刺激将有助于治疗外周循环衰竭。
Cutaneous nerves have vascular branches (VBs) that reach the arteries and are thought to be involved in arterial constriction. We aimed to examine the anatomical and histological relationship between the VBs of a cutaneous nerve in the foot and the acupuncture point LR3 (Taichong), which is a depression between the base of the first and second metatarsal bones on the dorsum of the foot and is a source point of the foot. We examined 40 cadaver feet to assess the distribution areas of the VBs of the medial branch of the deep peroneal nerve (MBDPN). MBDPNs were distally followed to identify the point where the VBs reached the arteries. The distance between the point and LR3 was measured. Sympathetic fibers in the VBs were histologically observed using tyrosine hydroxylase (TH) immunostaining. The VBs of the MBDPNs reaching the dorsal pedis arteries were observed in all specimens (100%). The mean distance between LR3 and the point where the VBs of the MBDPN reached the arteries was 3.2 ± 2.6 mm. Among the VBs, 70% were distributed proximal to LR3. Moreover, TH-positive fibers were present in the VBs. These findings revealed that a part of the MBDPN distributed the dorsal pedis artery and contained sympathetic fibers. We also found that the distribution area of the VBs was close to LR3. Our study provides anatomical evidence that LR3 is a specific area and its stimulation would be useful for treating peripheral circulatory failure.
