Original publication title: Three-Dimensional Models of Liver Vessels for Navigation during Laparotomic Attenuation of Intrahepatic Portosystemic Shunt in Dogs.

Plain-English summary
Four dogs with a liver condition called intrahepatic portosystemic shunt (IHPSS) underwent surgery to correct the problem, which can be complicated and risky. To help with the surgery, veterinarians used 3D printed models of each dog's liver based on detailed scans. This innovative approach made it easier to plan the surgery and quickly locate the abnormal blood vessel during the procedure, leading to less trauma and a better recovery for the dogs. The use of 3D models is a promising advancement in treating this challenging condition.

Abstract
Laparotomic attenuation of an intrahepatic portosystemic shunt (IHPSS) is more difficult than an extrahepatic one, and results in a higher risk of complications because the identification of the aberrant vessel in the liver remains often a challenge. Excessive preparation and traction of the parenchyma results in trauma, bleeding, and prolonged surgery, which is what worsens the prognosis. Therefore, based on computed tomographic angiography, we printed 3-dimensional (3D) individual patient liver models, scaled 1:1, and used them for surgery planning and as a guide during intraoperative identification of the shunt in four dogs with IHPSS. The advantages of the 3D technology are simple and precise planning of the surgery, fast intraoperative identification of the shunt, and low invasive dissection of the liver parenchyma. We conclude that 3D technology can potentially raise the recovery rate. To the best of our knowledge, this was the first application of 3D models in the surgery of canine IHPSS.
