Abstract

During a routine cadaveric dissection of the posterior abdominal wall, variations of the bilateral lumbar plexus and a variant saphenous nerve originating in the lower abdomen were noted and documented. The description of a saphenous nerve originating at the level of the lumbar plexus is, to the best of our knowledge, the first of its kind. Further study revealed more variations at the root of the lumbar plexus and bilateral branching patterns. A variant iliacus muscle entrapping the superior portion of the femoral nerve was also observed on the right side within the abdominal cavity. These variations are discussed in the context of risk of clinical intervention in this anatomical region..

隐神经的非典型起源和右侧髂骨肌的变异:一例报告。
在腹部后壁的常规尸体解剖过程中,注意到并记录了源自下腹的双侧腰丛和变异隐神经的变化。据我们所知,对起源于腰丛水平的隐神经的描述是同类描述中的第一个。进一步的研究显示,腰丛根部和双侧分支模式有更多的变化。在腹腔内的右侧也观察到一块不同的髂肌包裹股神经的上部。这些变化在该解剖区域的临床干预风险的背景下进行了讨论。。
