| Abstract: | A technic for percutaneous transjugular catheterization of the median sacral vein (MSV) was developed in the dog. This technic provides a means for visualizing the vertebral sinuses in the lumbo-sacral area. Temporary external occlusion of the caudal vena cava coincident with injection of contrast medium was necessary to get consistent, symmetrical filling of the vertebral sinuses. Dissections confirmed variation in location of the MSV and presence of valves at the terminus of this vessel. Angiograms performed using the seventh lumbar intervertebral vein, cranial gluteal vein, and internal iliac vein were less satisfactory due to incomplete filling of the vertebral sinuses. |
