Plain-English summary
A group of 31 dogs with a congenital portosystemic shunt (a blood vessel issue that can affect liver function) underwent surgery to correct the problem. Blood tests were taken before, during, and after the surgery to measure levels of lactate and other important blood gases. The surgery was successful in completely closing the shunt in 16 dogs, while 15 had only partial closure. Importantly, the study found no significant differences in blood test results between the dogs with complete or partial shunt closure, and none of the measurements were linked to any complications after surgery.

Abstract
Plasma concentration of lactate and the values of pH, pO(2) and pCO(2) were measured in the portal, systemic venous and, when possible, systemic arterial blood of 31 dogs with a single congenital portosystemic shunt, before and shortly after the temporary complete occlusion of the shunt, and at the end of surgery. At completion of the surgery, the shunt in 16 of the dogs had been occluded completely whereas in the other 15 it had been occluded only partially. There were no significant differences between any of the measurements of these variables in the portal venous, systemic venous or arterial plasma of any of the dogs, or between the values measured in the groups in which the shunts had been occluded completely or partially. Furthermore, there were no significant differences between the two groups of dogs in the arteriovenous gradients calculated at any of the sampling sites or sampling times. None of the variables was associated with the development of postoperative complications.
