This study was conducted to describe the ultrasonographic appearance and technique for the evaluation of sciatic nerve (ScN) in cats. An anatomical study was carried out using six feline cadavers to determine anatomic landmarks. An ultrasonographic 'in vitro' study was performed using eight pelvic limbs from four fresh feline cadavers to assess the ScN in three regions (glutea, femoralis and popliteal) using a 4-13MHz linear transducer. Five healthy adult experimental cats were employed for an 'in vivo' ultrasonographic study of the ScN using the same protocol described for the 'in vitro' study. The ultrasonographic images of the ScN were well correlated with those obtained in the anatomical study. The ScN was easily identified in all the approaches. The ScN was observed as a hypoechoic structure with internal echoes, outlined by hyperechoic lines. This study shows the usefulness of ultrasound to evaluate the entire pathology of the ScN in the cat.
本研究旨在描述猫坐骨神经（ScN）的超声表现及评估技术。利用六只猫的尸体进行解剖学研究以确定解剖标志。使用来自四只新鲜猫尸体的八个盆腔肢体进行超声“体外”研究，使用4-13MHz线性换能器在三个区域（臀区、股区和腘区）评估ScN。采用与“体外”研究相同的方案，对五只健康成年实验猫进行ScN的超声“体内”研究。ScN的超声图像与解剖学研究中获得的图像高度相关。在所有入路中ScN均易于识别。ScN表现为内部有回声的低回声结构，由高回声线勾勒出轮廓。本研究表明超声在评估猫ScN的整体病理学方面具有实用性。
