动脉接受来自周围神经的血管分支 (VBs)。VB 被认为与动脉收缩有关。尽管胫前动脉 (ATA) 接收 VB，但有关其分支模式和分布区域的信息仍然有限。本研究的目的是调查到达 ATA 的 VB 的解剖结构。检查了 40 个尸体肢体，以评估到达 ATA 的 VB 的分支模式和分布区域。到达 ATA 的 VB 从腓深神经 (DFN) 分叉，ATA 在每个肢体中接收到两个或三个 VB。测量了从腓骨头到 VB 到达 ATA 的点的以下平均距离：所有 VB、第 1 VB、第 2 VB 和第 3 VB。测量值分别为 51.5 ± 23.2 mm、33.3 ± 3.7 mm、53.3 ± 18.6 mm 和 72.2 ± 24.5 mm。在所有肢体中，DFN 和 ATA 在 DFN 分支到第 1 VB 后会聚。40个肢体中38个第2个VB和32个肢体中20个第3个VB分布在ATA和DFN交汇点附近的ATA。这些发现表明，所有到达 ATA 的 VB 都从四肢的 DFN 分叉出来。ATA 接收到两个或三个 VB，所有第 1 个 VB 都分配到靠近会聚点的 ATA。

Nerve branches to the anterior tibial artery: Clinical application

Arteries receive vascular branches (VBs) from peripheral nerves. VBs are thought to be involved in arterial constriction. Although the anterior tibial artery (ATA) receives VBs, information on their branching patterns and distribution areas remains limited. The aim of this study was to investigate the anatomical structures of the VBs reaching the ATA. Forty cadaver limbs were examined to assess the branching patterns and distribution areas of the VBs reaching the ATA. The VBs reaching the ATA ramified from the deep fibular nerve (DFN), and the ATA received two or three VBs in each limb. The following mean distances from the head of fibula to the points at which the VBs reached the ATA were measured: all the VBs, 1st VB, 2nd VB and 3rd VB. The measurements were 51.5 ± 23.2 mm, 33.3 ± 3.7 mm, 53.3 ± 18.6 mm, and 72.2 ± 24.5 mm, respectively. In all limbs, the DFN and the ATA converged after the DFN branched into the 1st VB. The 2nd VB in 38 of 40 limbs and the 3rd VB in 20 of 32 limbs were distributed in the ATA proximal to the convergence point of the ATA and the DFN. These findings revealed that all VBs reaching the ATA ramified from the DFN in all limbs. The ATA received two or three VBs, and all the 1st VBs distributed to the ATA proximal to the convergence point.
