Intraoperative ultrasonography of the vertebral canal in dogs

Intraoperative ultrasound (IOS) can provide details on various conditions of the spinal cord and vertebral canal. The aim of the present study was to evaluate the feasibility of using IOS in dogs undergoing spinal surgery and to describe the main findings. The vertebral canal of 21 dogs was examined with intraoperative ultrasonography: 13 underwent spinal surgery for removal of herniated intervertebral disc material, three for stabilization of vertebral fracture/luxation, two for removal of vertebral neoplasia, and three for cauda equina decompression. Particular attention was given to signs of cord compression. Intraoperative ultrasonography was feasible and useful in dogs undergoing surgery for spinal cord or cauda equina decompression and fracture stabilization. It was not paramount for locating the compression when this had been done via computed tomography (CT), but it showed alterations in spinal cord parenchyma not observed on CT and also confirmed adequate decompression of the spinal cord. The main advantages of intraoperative ultrasonography were estimation of vascularization and extent of spinal cord lesion. Most importantly, it allowed real time evaluation of the spinal cord and vertebral canal, which permits the modification of the surgical procedure.
