The spermatic ganglia are collections of sympathetic neuron cell bodies located within the cords of the infrarenal aortic plexus, positioned at the origin of the testicular arteries in males. During routine dissection of the aortic plexus at our institution, one specimen exhibited a second (accessory) testicular artery on the right side that coursed retrocaval. Histology was used to confirm the presence of an accessory right spermatic ganglion at the base of the accessory retrocaval testicular artery. Interestingly, the accessory spermatic ganglion was also supplied by its own right lumbar splanchnic nerve. This is the first case to describe the anatomy of an accessory spermatic ganglion in a specimen that exhibits an accessory testicular artery on the right side. This neurovascular variation is of interest to surgeons who aim to perform nerve-sparing retroperitoneal lymph node dissections for malignancy.
精索神经节是位于肾下主动脉丛索内的交感神经元细胞体集合,位于男性睾丸动脉的起始处。在我们机构对主动脉丛进行常规解剖时,一个标本显示右侧有一条副(额外)睾丸动脉,走行于腔静脉后方。组织学检查证实了在腔静脉后副睾丸动脉根部存在一个右侧副精索神经节。有趣的是,副精索神经节也由其自身的右腰内脏神经供应。这是首例描述右侧有副睾丸动脉的标本中副精索神经节解剖结构的病例。这种神经血管变异对于旨在为恶性肿瘤进行保留神经的腹膜后淋巴结清扫术的外科医生来说具有重要意义。
