The anterior cutaneous branches of the thoracolumbar spinal nerves enter the rectus sheath at its lateral border and perforate the muscle after travelling a short distance in the ventral direction. In this anatomical case series, we show that dye injection at the medial margin did not lead to reliable impregnation of the target nerves. The local anesthetic should therefore be injected at the lateral edge of the rectus sheath. Preceding surgical procedures to the ventral abdominal wall may affect the craniocaudal spread of local anesthetic.
胸腰段脊神经的前皮支在腹直肌鞘外侧缘进入该鞘，并在腹侧走行一小段距离后穿经此肌。在本解剖病例系列中，我们发现在内侧缘注射染料并不能可靠地使目标神经显影。因此，局部麻醉药应注射在腹直肌鞘的外侧缘。腹部前壁之前的外科手术可能会影响局部麻醉药的头尾向扩散。
