Celiac plexus block (CPB) and neurolysis (CPN) are used for pain management in people suffering from abdominal tumours or chronic pancreatitis. The fluoroscopically guided approach common in human medicine has not been described in veterinary settings. The aim of this study was to describe a fluoroscopic approach to the celiac plexus (CP) in fresh pig cadavers. Twelve animals were included in the procedure. Cadavers were positioned in sternal position and, under fluoroscopic guidance, a Chiba needle was inserted parasagittal at 6 cm from the spinal midline at the level of the last thoracic vertebra. From the left side, the needle was directed medio-ventrally with a 45° angle towards the T15 vertebral body; once the vertebral body was contacted, the needle was advanced 1 cm ventrally towards the midline. Iodinated contrast was injected to confirm the location. Following this, 2 mL of dye (China ink) was injected. A laparotomy was performed, and dyed tissue was dissected and prepared for both histochemical and immunohistochemical techniques. In 10 out of 12 samples submitted for histological evaluation, nervous tissue belonging to CP was observed. Fluoroscopy guidance allows for feasible access to the CP in swine cadavers in this study. Further studies are warranted to determine the efficacy of this technique in swine and other veterinary species.
腹腔神经丛阻滞（CPB）和神经松解术（CPN）用于治疗患有腹部肿瘤或慢性胰腺炎的患者的疼痛。在人类医学中常见的荧光镜引导方法在兽医领域尚未见报道。本研究的目的是描述在新鲜猪尸体中对腹腔神经丛（CP）进行荧光镜引导的方法。该操作纳入了12只动物。将尸体置于胸骨位，在荧光镜引导下，于最后胸椎水平距脊柱中线6 cm处旁矢状位插入一根千叶针。从左侧将针以45°角向腹内侧朝向第15胸椎椎体；一旦接触到椎体，将针向腹侧中线推进1 cm。注入碘化造影剂以确认位置。随后，注入2 mL染料（中国墨汁）。进行剖腹手术，解剖染色组织并准备用于组织化学和免疫组织化学技术。在提交组织学评估的12个样本中，有10个观察到属于CP的神经组织。在本研究中，荧光镜引导可使猪尸体中的CP易于触及。有必要进一步研究以确定该技术在猪和其他兽医物种中的疗效。
