Subarachnoid lumbar puncture is used commonly in the dog for cerebrospinal fluid collection and/or myelography. Here in we describe the percutaneous ultrasound anatomy of the lumbar region in the dog and a technique for ultrasound-guided lumbar puncture. Ultrasound images obtained ex vivo and in vivo were compared with anatomic sections and used to identify the landmarks for ultrasound-guided lumbar puncture. The ultrasound-guided procedure was established in cadavers and then applied in vivo in eight dogs. The anatomic landmarks for the ultrasound-guided puncture, which should be identified on the parasagittal oblique ultrasound image are the articular processes of the fifth and sixth lumbar vertebrae and the interarcuate space. The spinal needle is directed under ultrasound-guidance toward the triangular space located between the contiguous articular processes of the fifth and sixth lumbar vertebrae and then advanced to enter the vertebral canal. Using these precise ultrasound anatomic landmarks, an ultrasound-guided technique for lumbar puncture is applicable in the dog.
蛛网膜下腔腰椎穿刺术在犬类中常用于采集脑脊液和/或脊髓造影。在此，我们描述犬类腰椎区域的经皮超声解剖结构以及超声引导下腰椎穿刺的技术。将体外和体内获得的超声图像与解剖切片进行比较，并用于确定超声引导下腰椎穿刺的标志。在尸体上建立了超声引导程序，然后在八只犬类体内应用。超声引导穿刺的解剖标志，应在矢状斜位超声图像上识别，是第五和第六腰椎的关节突以及弓间间隙。在超声引导下，将脊髓针指向第五和第六腰椎相邻关节突之间的三角形间隙，然后推进进入椎管。利用这些精确的超声解剖标志，超声引导下的腰椎穿刺技术适用于犬类。
